09/28/2020 11:59 GMT — 1 in 3 parents plan to skip flu shots during pandemic
A recent poll investigated parental attitudes toward flu vaccinations this season. They found that 1 in 3 parents don’t plan on vaccinating their children against the flu this year. The most common reason involved concerns about side effects.
In August 2020, the survey — called the C.S. Mott Children’s Hospital National Poll on Children’s Health — took data from 1,992 parents of children aged 2–18. The parents reported their reasons for not vaccinating their children, most commonly: concerns about side effects (42%) and a belief that the vaccine is not necessary (40%) or effective (32%).
A further 14% of parents who are not planning on having their children vaccinated cited concerns about visiting healthcare settings during the COVID-19 pandemic.
In their report, the researchers explain: “Public health experts have emphasized the particular importance of flu vaccination during the COVID pandemic as a tool to limit the stress on healthcare systems. This includes reducing the number of influenza-related hospitalizations and doctor visits and decreasing the need for diagnostic tests to distinguish influenza from COVID.”
They continue, “Children should get flu vaccine to protect themselves and to prevent the spread of influenza to family members and others.”

09/28/2020 11:16 GMT — Anxiety symptoms increased during the pandemic, Google Trends data show
A recent study, which used data from Google Trends, explored the impact of the pandemic on mental health in the United States. Overall, the authors noted that searches for “worry,” “anxiety,” and “therapeutic techniques to manage worry and anxiety” have increased during the pandemic.
Discussing their use of Google Trends, lead author Dr. Michael Hoerger explains, “Although by no means a ‘window into the soul,’ people’s search terms reflect relatively uncensored desires for information and thus lack many of the biases of traditional self-report surveys.”
The findings appear in the journal Psychological Trauma: Theory, Research, Practice, and Policy. Dr. Hoerger paints a somewhat bleak picture of the future, saying:
“Over time, we should begin to see a greater decline in societal mental health. This will likely include more depression, PTSD, community violence, suicide, and complex bereavement. For each person that dies of COVID, approximately nine close family members are affected, and people will carry that grief for a long time.”

09/25/2020 10:16 GMT — US COVID-19 cases pass 7 million
On Thursday, the total number of COVID-19 cases in the United States surpassed 7 million. This equates to 1 in 5 of all global cases. The U.S. has also registered more than 200,000 deaths. To date, California has reported the highest number of cases with 800,000.

09/25/2020 09:38 GMT — Flu vaccinations not linked to increased COVID-19 risk
A new study concludes that the flu vaccine does not increase a person’s risk of getting COVID-19. The scientists also demonstrate that the vaccine is not associated with severe illness and death from the disease. The results appear in theJournal of Clinical and Translational Science.
The authors explain that the flu shot will help prevent a “twindemic” when the flu season overlaps the ongoing COVID-19 pandemic.
Lead researcher Dr. Joe Zein writes: “Our findings suggest that we should proceed as usual with our vaccination strategy for global influenza this flu season. […] Getting the annual flu vaccine remains the best safeguard against the influenza virus — both for yourself and the people around you.”

09/24/2020 09:33 GMT — Most people in the United States could be vaccinated by July 2021
Despite promising candidates, there is still no vaccine for COVID-19. However, according to Robert Redfield — the head of the Centers for Disease Control and Prevention (CDC) — the “entire American public [could be] completely vaccinated” by July. He estimates that 700 million doses will be available by April.

09/24/2020 08:57 GMT — COVID-19: Tackling the root cause of inflammation
Scientists have proposed that an existing drug may help prevent an excessive, life threatening immune reaction to SARS-CoV-2 in susceptible individuals. The drug might work by easing cellular stress that the virus causes. Their proposal appears in the journal Cytokine & Growth Factor Reviews.
“When cells are stressed by infection, they call the cytokines, and the more stressed they are, the more persistent they become, provoking this uncontrolled inflammation,” explains senior study author Iván Durán. “Hence, one possible treatment for COVID-19 is to reduce cellular stress.”
However, the authors are also clear that scientists will need to conduct more research to see if their model works outside of their laboratory.

09/23/2020 09:13 GMT — Republican governors took longer in making masks a requirement
A recent study shows that Republican governors waited longer than Democratic governors to issue mask-wearing mandates as a preventive measure against COVID-19. According to the data, states with Republican governors delayed issuing mask mandates by an average of 29.9 days compared with states with Democratic governors. 
The study paper is available on the preprint server medRxiv, so it has not yet undergone peer review. Discussing the factors around this disparity, lead author Christopher Adolph explains: 
“President Trump spent crucial months deriding masks and refusing to wear them in public. This deepened a partisan divide that few Republican governors have been willing to cross, even as their states’ cases shot up this summer.”

09/22/2020 15:32 GMT — MNT video update: ‘Long COVID’
09/22/2020 10:08 GMT — United Kingdom experiences increased numbers of infections
Recently, the number of COVID-19 cases in the U.K. has surged. Although death rates remain low, officials are concerned. The government’s chief scientific adviser, Sir Patrick Vallance explains, “If this continues along the path, the number of deaths directly from [COVID-19] could rise on an exponential curve.”
He continues: “We have, in a bad sense, literally turned a corner, although only relatively recently. At this point, the seasons are against us, we are now going into the seasons, late autumn and winter, which benefit respiratory viruses and it is very likely they will benefit [COVID-19] as they do flu.”
Cabinet Office minister Michael Gove has told people to work from home “if they can.” Additionally, the government is pausing trials of spectators attending sporting events, and hospitality venues — such as restaurants and bars — must close at 10:00 p.m. from Thursday onward.

09/22/2020 09:32 GMT — Specialists discuss diagnosis and management of ‘long COVID‘
Following SARS-CoV-2 infection, some people experience weeks or even months of symptoms, which can include extreme fatigue and fever. Experts refer to this lingering condition as long COVID. In a recent BMJwebinar, specialists discussed how best to support these people.
During the webinar, six specialists from the United Kingdom and Germany talked about the best approaches to the diagnosis, management, and prognosis of long COVID.

09/21/2020 11:15 GMT — COVID-19: How many patients return to the hospital after discharge?
Many people who arrive at the emergency room with mild COVID-19 symptoms are discharged upon initial presentation. A recent study investigates how many of these individuals are later admitted to the hospital. The authors found that doctors admitted almost 5% of these people within 72 hours. 
In all, 66 patients (4.7%) returned to the emergency room and were admitted to the hospital within 72 hours because of worsening symptoms. An additional 56 patients (3.9%) also returned to the emergency room but were again discharged.
The research, which appears in the journal Academic Emergency Medicine, also identifies certain factors associated with an increased risk of readmission. These factors include age, obesity, hypertension, and hypoxia.

09/21/2020 10:47 GMT — US cases of depression have tripled during the COVID-19 pandemic
A recent study, which features in the journal JAMA Network Open, finds that the number of adults in the United States who are experiencing depression has tripled during the pandemic. The number of affected individuals has risen from 8.5% before the pandemic to 27.8%.
Among other findings, the researchers determined that people with less than $5,000 in savings were 50% more likely to experience symptoms of depression than those who had more.
Discussing ways to alleviate this, lead author Catherine Ettman says:
“There may be steps that policymakers can take now to help reduce the impact of COVID-19 stressors on depression, such as eviction moratoria, providing universal health insurance that is not tied to employment, and helping people return to work safely — for those able to do so.”

09/18/2020 15:00 GMT — Regional WHO director: September cases spike signals ‘wake-up call’ for EuropeDr. Hans Henri P. Kluge, the World Health Organization’s (WHO) Regional Director for Europe, held a press conference yesterday in Copenhagen, Denmark.
In it, he reminded Europeans that, “Last week, the region’s weekly tally exceeded 300,000 cases,” and “More than half of European countries have reported a greater than 10% increase in cases in the past 2 weeks.”
Dr. Kluge said these figures reflect higher testing rates, but they also indicate “alarming rates of transmission.”
The numbers should serve as a “wake-up call for all of us,” he continued. The WHO representative called for solidarity and a concerted, “amplified effort” from all European Member states.

09/18/2020 12:00 GMT — COVID-19 is here to stay, new research predictsA new study predicts that the novel coronavirus is here to stay and will have a seasonal pattern, similar to the flu, wherein transmission decreases in summer and increases again in winter. This is largely due to the effect of the climate on viral transmission, the authors say. 
Judging by data on similar “enveloped” viruses, cold weather may lead to the stabilization of SARS-CoV-2. Conversely, UV light in hot summer months may kill the new coronavirus. The study looks at other considerations, too.
“Therefore, the public will need to learn to live with it and continue practicing the best prevention measures, including wearing of masks, physical distancing, hand hygiene, and avoidance of gatherings,” says senior study author Hassan Zaraket, Ph.D.
However, the authors emphasize that their predictions are merely a “best guess,” and that this predicted seasonality is heavily reliant on the development of a vaccine and the achievement of significant herd immunity.
“This remains a novel virus, and despite the fast-growing body of science about it, there are still things that are unknown. Whether our predictions hold true or not remains to be seen in the future. But we think it’s highly likely, given what we know so far, [that] COVID-19 will eventually become seasonal, like other coronaviruses,” says Zaraket.

09/17/2020 10:00 GMT — Trump claims vaccine will be ready next month; experts disagree
Yesterday, President Donald Trump predicted that a safe, effective vaccine would be ready to use in October and rolled out across the United States soon after. His statement is in direct contradiction to comments made by the government’s top health experts. 
If scientists deem one of the experimental vaccines they are currently testing as safe and effective soon, experts believe there will still be some time before it is widely available. 
For instance, Dr. Robert R. Redfield, Director of the Centers for Disease Control and Prevention (CDC), believes that it may be available for frontline staff toward the end of the year or in January 2021.
Dr. Redfield also explained that should scientists develop a successful vaccine, they would probably not deploy it on a wider scale until late spring or summer.

09/17/2020 08:57 GMT — COVID-19: Antibody fragment could prevent infection
A recent study, which appears in the journal Nature Communications, suggests that an antibody fragment, called a nanobody, can neutralize SARS-CoV-2. According to the authors, it is possible to produce these fragments cheaply and at scale, making it a promising candidate for the widespread prevention of COVID-19.
Senior study author Prof. Gerald McInerney says, “We hope our findings can contribute to the amelioration of the COVID-19 pandemic by encouraging further examination of this nanobody as a therapeutic candidate against this viral infection.”

09/16/2020 09:21 GMT — Links between obesity, COVID-19, and bacteria
A recent review, which appears in the journal eLife, examines how the microbiome interacts with COVID-19 in the lungs. The authors believe their findings help explain why people with obesity and diabetes are more likely to develop severe acute respiratory syndrome (SARS) after infection.
The authors conclude, “The appearance of bacteria, their products, or both in the lungs of [people with obesity and diabetes] promotes interactions between viral and bacterial pathogens, resulting in a more severe lung injury in COVID-19.”

09/16/2020 09:14 GMT — India passes 5 million cases
According to officials, India has now registered more than 5 million cases of COVID-19 and 82,066 related deaths. In the past 24 hours alone, the Health Ministry has reported 90,123 cases and 1,290 deaths. Already in September, they have registered more than 1 million cases.
The United States still has the highest total number of COVID-19 cases with 6.6 million, but experts believe India will surpass this figure within the next few weeks.

9/15/2020 09:58 GMT — Chinese vaccine ready by November?
According to Chinese officials, a COVID-19 vaccine could be ready for the public in November. Scientists are currently testing four candidate vaccines in late-stage clinical trials, and three of these have already been offered to frontline staff.
According to Guizhen Wu, the chief biosafety expert at China’s Centers for Disease Control and Prevention (CDC), phase 3 clinical trials are going well.

09/15/2020 09:06 GMT — US COVID-19 cases down 15% in past week
Comparing the past 7 days with the 7 days before, cases of COVID-19 in the United States have dropped 15%. New cases have now dropped for 8 consecutive weeks. The number of coronavirus-related deaths has also fallen for 4 weeks in a row.
However, the number of cases in some states — including North Dakota, Wisconsin, Delaware, New Hampshire, and New Jersey — has risen for 2 weeks in a row.
Last week, on average, the U.S. tested 650,000 people each day. Of these individuals, 5.4% tested positive. This figure has dropped steadily over the past 6 weeks.

09/14/2020 09:37 GMT — Asthma may not increase the risk of severe COVID-19
A recent review finds that the proportion of all patients hospitalized with COVID-19 who also have asthma is similar to the prevalence of asthma in the wider population. The authors conclude that asthma is not a “significant risk factor for developing severe COVID-19 requiring hospitalization.”
The researchers also found that patients hospitalized with COVID-19 who had asthma were no more likely to be intubated than other patients without asthma.
“The CDC [place] people with asthma at higher risk [of] COVID-related hospitalization,” explains senior author Dr. Fernando Holguin. “However, many international studies show low numbers of [people with asthma] among hospitalized COVID-19 patients. These findings challenge the assumption about asthma as a risk factor.”

09/10/2020 10:34 GMT — Critically ill patients have robust immunity to new coronavirus
A recent study suggests immune responses to SARS-CoV-2 in severely ill patients are as strong or stronger than those of patients with milder COVID-19. This adds to the evidence that the immune system itself is to blame for the most life-threatening form of the infection.
The results of the study appear in the journal Cell Reports Medicine. Lead author Prof. Nina Babel explains, “Even though further studies will be necessary to understand the specific mechanism of COVID-19 development, our data suggest that excessive SARS-CoV-2-specific T cell response can cause [immune damage] leading to COVID-19-related lung failure.”

09/10/2020 09:18 GMT — Promising results for Russian vaccine
A new paper, which appears in The Lancet, details the results of two early phase clinical trials of the Russian Sputnik V vaccine. According to the authors, the vaccine “has a good safety profile and induced strong humoral and cellular immune responses in participants.”
However, it is worth noting that the researchers had designed the trials to assess the safety and immunogenicity of the vaccine, not to evaluate whether it can prevent COVID-19. Senior author Prof. Alexander Gintsburg explains the next steps:
“The phase 3 clinical trial of our vaccine was approved on 26 August, 2020. It is planned to include 40,000 volunteers from different age and risk groups and will be undertaken with constant monitoring of volunteers through an online application.”

09/09/2020 08:32 GMT — AstraZeneca’s COVID-19 vaccine trials halted
According to AstraZeneca Plc., they halted a large-scale clinical trial of a COVID-19 vaccine because one participant developed an unexplained illness. The World Health Organization (WHO) had described this vaccine, developed by the University of Oxford in the United Kingdom, as a leading candidate.
AstraZeneca has paused trials while an independent committee reviews the safety data. In a statement, the company explain: “This is a routine action, which has to happen whenever there is a potentially unexplained illness in one of our trials.”
Although the company has not disclosed the nature of the illness, doctors expect the individual to recover. At this stage, it is not clear whether the vaccine was directly responsible for the illness.

09/04/2020 11:09 GMT — COVID-19-associated health worker deaths
According to a new Amnesty International report, globally, more than 7,000 health workers have died after contracting COVID-19. Mexico has registered the highest number of health worker fatalities, with a total of 1,320 deaths. The report states that in Mexico, hospital cleaners are particularly at risk.
The analysis also reports high numbers of health worker fatalities in the United States (1,077), United Kingdom (649), Brazil (634), Russia (631), India (573), and South Africa (240).
According to Steve Cockburn, Amnesty International’s head of economic and social justice, “For over 7,000 people to die while trying to save others is a crisis on a staggering scale. Every health worker has the right to be safe at work, and it is a scandal that so many are paying the ultimate price.”
“Many months into the pandemic, health workers are still dying at horrific rates in countries such as Mexico, Brazil, and the [U.S.]“, he continues, “while the rapid spread of infections in South Africa and India show the need for all states to take action.”
Speaking about the way forward, Cockburn explains, “There must be global cooperation to ensure all health workers are provided with adequate protective equipment so they can continue their vital work without risking their own lives.”
Although the figures in the analysis are stark, the authors of the report remind us that “These figures are likely to be a significant underestimate, due to underreporting by many of the countries included in the analysis.”

09/03/2020 10:03 GMT — COVID-19: Breathing problems are the most common reason for returning to the hospital
According to a new study, it is relatively rare for COVID-19 patients to return to the hospital within 2 weeks of discharge. Individuals with hypertension or chronic obstructive pulmonary disease are the most likely to return.
Using electronic health records, the authors of the latest study followed 2,864 discharged patients. Of these, 103 (3.6%) returned for emergency care, and, in total, the hospitals readmitted 56 patients.
People with breathing difficulties were the most likely group to return to the hospital, accounting for half of all return visits. The authors published their results in the Journal of General Internal Medicine.

09/03/2020 09:05 GMT — Winter flu-like illnesses could have been COVID-19
The results of a recent analysis suggest that thousands of people who had flu-like symptoms during the winter of 2019 may actually have had COVID-19. The findings are based on retested throat swabs from people in Wuhan, China, and Seattle, WA.
The results, which appear in the journal EClinicalMedicine, suggest that the early spread of COVID-19 could have been far greater than experts initially thought.
As senior author Prof. Lauren Ancel Meyers explains, “Even before we realized that COVID-19 was spreading, the data imply that there was at least one case of COVID-19 for every two cases of flu.”

09/02/2020 13:45 GMT — US confirms it will not take part in WHO-led coronavirus vaccine initiative
In communication with The Washington Post yesterday, Judd Deere, a spokesperson for the White House, confirmed that the United States will not be joining COVAX, the international initiative for the development of a vaccine against SARS-CoV-2, the coronavirus that causes COVID-19. This initiative is co-led by the World Health Organization (WHO), and it currently involves 172 countries.
“The [U.S.] will continue to engage our international partners to ensure we defeat this virus, but we will not be constrained by multilateral organizations influenced by the corrupt [WHO] and China,” Deere told The Washington Post.
This news follows U.S. President Donald Trump’s decision to formally initiate the States’ withdrawal from the WHO in July after he claimed that China heavily influences the United Nations (UN) agency in their decision-making.

09/02/2020 09:36 GMT — Link found between metabolic syndrome and worse COVID-19 outcomes
A recent study concludes that people with metabolic syndrome are more likely to have worse COVID-19 outcomes — including requiring ventilation and death. The results appear in the journal Diabetes Care. 
Metabolic syndrome is a cluster of conditions, which include obesity, hypertension, and diabetes. People with metabolic syndrome have an increased risk of cardiovascular disease.
After accounting for a range of variables — including age, sex, race, and the hospital location — the researchers found that people with metabolic syndrome were 3.4 times more likely to die from COVID-19 than people without metabolic syndrome.

09/01/2020 12:00 GMT — Treating COVID-19 may increase antibiotic resistance
A recent study, which appears in the Journal of Antimicrobial Chemotherapy, concludes theincreased use of antibiotics during the COVID-19 pandemic may be placing an added burden on wastewater treatment works. This might lead to raised levels of antibiotics in rivers.
Although antibiotics cannot treat viruses, such as SARS-CoV-2, doctors commonly prescribe them to people who are hospitalized with COVID-19 to prevent secondary bacterial infections.
“From our previous research, we know that significant quantities of commonly prescribed drugs pass through treatment works and into our watercourses,” explains lead author Prof. Sean Comber.
Co-author Prof. Mathew Upton adds, “It is clear that mass prescribing of antibiotics will lead to increased levels in the environment, and we know that this can select for resistant bacteria. Studies like this are essential so that we can plan how to guide antibiotic prescription in future pandemics.”

09/01/2020 11:23 GMT — Blood pressure drugs may improve COVID-19 survival
A recent review, which appears in the journal Current Atherosclerosis Reports, concludes that people taking certain drugs for high blood pressure had a lower risk of severe COVID-19 and death than thosewho were not taking these medications.
Doctors commonly prescribe angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) to treat high blood pressure.
Both drugs interact with ACE2 receptors. These receptors are also the entry point in the cell for SARS-CoV-2. Some researchers speculated that taking ACE inhibitors or ARBs might increase the number of ACE2 receptors and, therefore, exacerbate the infection.
“[What we] showed was that there is no evidence that these medications might increase the severity of COVID-19 or risk of death,” explains lead researcher Dr. Vassilios Vassiliou. “On the contrary, we found that there was a significantly lower risk of death and critical outcomes, so they might, in fact, have a protective role — particularly in patients with hypertension.”

08/28/2020 15:00 GMT — Scientists reveal specific order of COVID-19 symptomsMNT reported on new research that found that individuals with a SARS-CoV-2 infection will likely experience symptoms in the following order:

  1. fever
  2. coughing and muscle pain
  3. nausea, vomiting, or both
  4. diarrhea

The new study — which appears in the journal Frontiers in Public Health — reached the above conclusion after analyzing the rates of symptom incidence of 55,924 confirmed COVID-19 cases in China.
The scientists supplemented their data with another 1,099 cases collected by the National Health Commission of China and compared COVID-19 with influenza and two other diseases caused by coronaviruses: SARS and MERS.
“This order is especially important to know when we have overlapping cycles of illnesses like the flu that coincide with infections of COVID-19,” says the study’s senior author, Prof. Peter Kuhn, from the University of Southern California.
“Doctors can determine what steps to take to care for the patient, and they may prevent the patient’s condition from worsening.”

08/28/2020 14:00 GMT — 20% of nursing homes in the US lack PPE
A new study that appears ahead of print in the journal Health Affairs, finds that over 20% of US nursing homes lack sufficient personal protective equipment (PPE).
This is despite the fact that nursing home residents make up almost 50% of all COVID-19 deaths in the U.S. “Twenty percent is a lot, given where we are in the course of this pandemic. I would have hoped by month six we would be close to 0%,” says lead author Brian E. McGarry, assistant professor of geriatrics/aging and public health sciences at the University of Rochester Medical Center in New York. 
For their study, McGarry and colleagues used data from the Centers for Medicare and Medicaid Services (CMS) COVID-19 Nursing Home Database, which amassed responses from 15,035 nursing homes.

08/27/2020 14:00 GMT — CDC changes testing guidance, scientists express concern
Previously, the testing guidelines on the Centers for Disease Control and Prevention (CDC) website read: “Testing is recommended for all close contacts of persons with SARS-CoV-2 infection. Because of the potential for asymptomatic and pre-symptomatic transmission, it is important that contacts of individuals with SARS-CoV-2 infection be quickly identified and tested.”
On August 24, the CDC updated their testing guidelines. According to their website, “Diagnostic testing categories have been edited to focus on testing considerations and actions to be taken by individuals undergoing testing.”
Now, the guidelines read: “If you have been in close contact (within 6 feet) of a person with a COVID-19 infection for at least 15 minutes but do not have symptoms, you do not necessarily need a test unless you are a vulnerable individual or your health care provider or State or local public health officials recommend you take one.”
Scientists and other health experts have expressed concern over these changes. Prof. Leana Wen from George Washington University and former health commissioner in Baltimore, MD, tweeted: “I still can’t make sense of @CDCgov change in guidance.”
“An estimated 40-50% of people with #covid19 are asymptomatic. Those exposed to the virus need to know to protect their family members & the public. One has to wonder: is this change because we don’t have enough tests?”

08/27/2020 13:00 GMT — ‘We now have clear data’ that the immune response is ‘considerably different between the sexes’Since the beginning of the pandemic, scientists have been intrigued by sex differences in COVID-19 — specifically, that female patients tend to have better overall outcomes than their male counterparts.
Scientists have not known whether this is due to immunological differences or environmental factors.
New research helps settle the matter by exploring differences between the sexes’ immunological responses to SARS-CoV-2.
Prof. Akiko Iwasaki, of the Department of Immunobiology at Yale University, in New Haven, CT, and colleagues took nasal, saliva, and blood samples from COVID-19 patients and healthy participants. 
The authors performed analyses of viral loads, plasma cytokines, tests for SARS-CoV-2-specific antibodies, and blood cell phenotyping in the COVID-19 patients.
The team followed the evolution of immune markers over time, as the disease progressed. Ultimately, they found key differences between the sexes, including:

  • Male patients had higher levels of specific cytokines. These inflammatory proteins are a natural part of the immune response, but they can lead to the potentially fatal “cytokine storm” phenomenon in severe cases of COVID-19.
  • Female patients had a “significantly more robust T cell activation than male patients.” T cells are white blood cells that play an important role in the immune response to SARS-CoV-2 infection.
  • Over time, the team found, poor T-cell activation in male patients led to worsening of COVID-19.

“We now have clear data suggesting that the immune landscape in COVID-19 patients is considerably different between the sexes and that these differences may underlie heightened disease susceptibility in men,” says Prof. Iwasaki.

08/26/2020 09:54 GMT — Hydroxychloroquine: The research continues
This week, scientists have published two new studies that investigate hydroxychloroquine. One study looks at the long-term safety of thedrug when used to treat rheumatoid arthritis. The second study examines itsimpact in hospitalized COVID-19 patients.
The rheumatoid arthritis study appears in Lancet Rheumatology. Although the research is not directly related to COVID-19, the findings are relevant. The authors conclude:
“Hydroxychloroquine treatment appears to have no increased risk in the short term among patients with rheumatoid arthritis, but in the long term it appears to be associated with excess cardiovascular mortality.”
The authors of the second study, which appears in the European Journal of Internal Medicine, asked whether hydroxychloroquine reduced in-hospital mortality in patients with confirmed SARS-CoV-2 infections. 
Although the study was observational, the authors conclude hydroxychloroquine “was associated with a 30% lower risk of death in COVID-19 hospitalized patients.”
These results, which contradict similar, recent studies, are likely to spark fresh debate.
Read MNT’s article that explains how hydroxychloroquine has ignited a fire between medicine and politics.
08/26/2020 09:40 GMT — US colleges experience spike in cases
As many colleges begin their fall semester, some are struggling with high numbers of students testing positive for SARS-CoV-2. For instance, since August 19, officials from the University of Alabama have registered more than 550 positive tests.
Most of these cases were recorded at the university’s main campus in Tuscaloosa. In response, the mayor of Tuscaloosa has ordered bars to shut for 2 weeks and restricted the activity of other establishments.
At the University of Southern California’s University Park Campus in Los Angeles, 100 students are currently in a 14-day quarantine following exposure to the virus.
Last week, after a sharp rise in COVID-19 cases, the University of North Carolina at Chapel Hill canceled all in-class teaching.

08/25/2020 14:08 GMT — Scientists report first case of reinfection
A new study paper documents the case of a 33-year-old man in China who appears to have contracted SARS-CoV-2 twice. He was treated for a mild case of COVID-19 in a hospital in March and tested positive again almost 5 months later.
Scientists have determined that the virus of the second infection was genetically different from the virus of the first.
The paper has not yet been published in a peer-reviewed journal. However, the authors, researchers from The University of Hong Kong, say that that their manuscript has been accepted by the journal Clinical Infectious Diseases.
One of the authors, Dr. Kelvin To, writes, “This case proves that at least some patients do not have lifelong immunity.”
The researchers have only released parts of the paper online. In the text that has been made public, the authors argue that this case demonstrates that herd immunity is an impossibility and that a vaccine will not work.
However, other experts take a different view. For instance, Prof. Paul Hunter, from the University of East Anglia’s Norwich Medical School, in the United Kingdom, explains:
“The implications of this finding should not be overstated. It is quite likely that subsequent infections do not cause as severe an illness as the first episode because of some degree of residual immunity, which may not be sufficient to stop the infection but [may] be enough to reduce the risk of severe illness.”
He also explains that the viral load might not be as high in a second infection. Rather than conclude that immunization will never work, Prof. Hunter writes, “We need more information about this case and other cases of reinfection before we can really understand the implications.”
Prof. Brendan Wren, from the London School of Hygiene and Tropical Medicine, calls for similar restraint: “With over 3 million cases of COVID-19 worldwide, the first reported case of a potential reinfection with SARS-CoV-2 needs to be taken into context. […] This is a very rare example of reinfection, and it should not negate the global drive to develop COVID-19 vaccines.”
Dr. Julian Tang, from the University of Leicester, in the U.K., also believes that we should wait for further details before deciding that a future vaccine will be useless.
For instance, he outlines a theoretical alternative, in which there is “an initial coinfection with two different SARS-CoV-2 viral clades — with one initial predominant clade, then with the other minority clade just persisting longer than the predominant one.” 
In other words, both strains could, potentially, have been present in the man from the start, with one strain simply surviving longer. Although theoretical, this possibility underlines the need for more detail before making wide-ranging conclusions.
It is also worth noting that, in this individual, the second case was asymptomatic. The man had undergone a routine test as he passed through a Hong Kong airport.

08/25/2020 10:36 GMT — Pandemic slows throughout much of the world
On Monday, the World Health Organization (WHO) published their weekly epidemiological report. In the update, they explain that, although the pandemic continues, it is slowing in most regions. However, some areas are still experiencing increasing numbers of cases.
As the report explains, “With the exception of the South-East Asia and Eastern Mediterranean regions, a decrease in the weekly case incidence was reported across WHO regions in the last 7 days.”
Last week, the Americas remained the most affected region, accounting for 50% of new cases and 62% of deaths. However, the report explains that this region also experienced the largest decrease compared with the previous week.

08/24/2020 10:32 GMT — Is COVID-19 more dangerous because SARS-CoV-2 reduces specific microRNAs?
The authors of a new study ask whether microRNAs (miRNAs) might help explain why the novel coronavirus is particularly deadly. They conclude that SARS-CoV-2 might reduce miRNA levels in a way that assists viral replication and blocks the host immune response. 
miRNAs are short, noncoding RNAs that regulate gene expression. They also help fight viruses by latching onto viral RNA and cutting it. This means that if miRNAs are inhibited, viruses are more likely to replicate.
The authors of the new study found that SARS-CoV-2 may serve as a miRNA sponge, reducing levels of miRNA in the cell and making the virus more hazardous.

08/21/2020 09:30 GMT — Electric cooker can effectively sanitize N95 masks
N95 respirators are a vital part of healthcare workers’ personal protective equipment. However, people can only use them once, and they are now in short supply. A recent study demonstrates that dry heat from an electric cooker can effectively sanitize these masks without compromising their effectiveness.
The authors published their findings in the journal Environmental Science & Technology Letters. They found that 50 minutes of dry heat at 212ºF (100ºC) successfully decontaminated N95 respirators.
Co-author of the study Prof. Vishal Verma explains, “The respirators maintained their filtration capacity of more than 95% and kept their fit, still properly seated on the wearer’s face, even after 20 cycles of decontamination in the electric cooker.”

08/20/2020 10:11 GMT — New York teachers threaten strike
Yesterday, New York City’s United Federation of Teachers (UFT), which represents 133,000 public school teachers, voiced concerns about the city’s return-to-school plan. They promised to strike or bring legal action unless the district implements tighter safety measures and an improved COVID-19 testing plan.
At a briefing, UFT President Michael Mulgrew said, “The minute we feel that the mayor is trying to force people into a situation that is unsafe […] we go to court, we take a job action.”
However, local laws state that public employees are barred from striking. During a school tour in Brooklyn, Mayor Bill de Blasio said, “any union leader who talks about doing something illegal should really think twice about what he’s saying.”

08/20/2020 09:36 GMT — Will the COVID-19 pandemic and Black Lives Matter movement change science and society?
Medical News Today recently published an opinion piece by Winston Morgan, Ph.D., from the University of East London in the United Kingdom. In the article, he discusses a recent review into why COVID-19 disproportionately affects people from marginalized racial and ethnic groups. 
He explains how the review’s “overwhelming message was that the cumulative effects of structural racism on BAME [Black, Asian, and minority ethnic] groups was the major contributing factor.” 
Morgan also highlights why large-scale societal changes need more than sentiment to become reality. He writes:
“Major changes require the transfer of privilege from those who have always benefited from it to those who have never had privilege, a step that many, even those who advocate equality, are reluctant to make when faced with real choices.”

08/20/2020 09:13 GMT — Dr. Fauci quizzed at Healthline Town Hall meeting
This week, Dr. Anthony S. Fauci spoke about COVID-19 at a Town Hall meetingthat Healthline organized. During the discussion, he spoke about children returning to schools, his hopes for a vaccine, and experimental treatments that scientists are currently exploring.
Talking about reopening schools, Dr. Fauci said, “The general default position to reopen schools should be to try as best as you can to open up schools for the psychological health of the children and the secondary downstream ripple effects of the family that might have to interrupt work to take care of kids.”
However, he also makes it clear that “you have to pay attention to the safety and health and welfare of the children and teachers as well as the parents and relatives. With that as a background, we live in a big country that has different levels of infections.”

08/18/2020 10:24 GMT — Researchers call out lack of diversity in COVID-19 clinical trials
Marginalized people experience disproportionality higher rates of COVID-19 infection, hospitalization, and death. Despite this fact, according to a new perspective article in the New England Journal of Medicine (NEJM), they are significantly underrepresented in COVID-19 clinical trials.
The authors explain that clinical trials, in general, tend to lack diversity, and COVID-19 studies are no different. This fact makes it difficult to know whether interventions designed for COVID-19 will benefit those who are at most risk of the disease.
As an example, the authors explain that “[t]he modest benefit seen in time to clinical improvement with remdesivir may not be generalizable to minority populations, given the differences in disease severity and outcomes.”

08/17/2020 10:42 GMT — Scientists revise COVID-19 incubation period to 7.7 days
In a new study, scientists analyzed data from more than 1,000 people who had contracted SARS-CoV-2 in Wuhan, China. The team concludes that the average incubation period for COVID-19 may be longer than scientists had previously thought. They have published their findings in the journal Science Advances.
The incubation period of a disease is the time between the infection and the emergence of symptoms. Current estimates of the incubation period for COVID-19 are 4–5 days.
However, the new study concludes that the median period is 7.76 days. The researchers also found that in 10% of cases, the incubation period was over 14 days, and in 1% of cases, it was more than 20 days.

08/13/2020 13:25 GMT — Almost 6% of UK adults have antibodies to SARS-CoV-2
In a recent study, 100,000 adults in the United Kingdom completed a home-based antibody test. The researchers found that almost 6% of the population has antibodies to SARS-CoV-2.
A team at Imperial College London conducted the study, called the Real Time Assessment of Community Transmission. The results are available on a preprint server and are awaiting peer review.
The authors show that, among other findings, the proportion of people with SARS-CoV-2 antibodies varies by region. For instance, 13% of adults in London tested positive for the antibodies, compared with only 3% of people in the Southwest.
Also, certain groups were more likely to test positive, such as healthcare staff and people who work in care homes.
The team also found that people who are Black, Asian, or of other marginalized ethnic and racial groups are more likely than white people to test positive for the antibodies.
Overall, 17% of Black people,12% of Asian people, and 12% of people of other marginalized ethnic and racial populations tested positive, compared with 5% of white people.
When the researchers accounted for age and key worker status, this gap was reduced. But, as the authors explain, race and ethnicity “remained important predictors, and reflect [a] starkly uneven experience of the COVID-19 epidemic across society.”
The scientists also noted differences across age groups. For instance, 8% of people aged 18–24 tested positive, compared with 3% of people aged 65–74.
From the data, the scientists calculate that the overall infection fatality ratio is 0.9%. This means that almost 1 in 100 people with a SARS-CoV-2 infection died.
“There are still many unknowns with this new virus, including the extent to which the presence of antibodies offers protection against future infections,” explains Prof. Graham Cooke, who led the study. 
He continues: “Using the finger prick tests suitable for large-scale home testing has given us [the] clearest insight yet into the spread of the virus in the country and who has been at greatest risk. These data will have important implications for decisions around ongoing control measures in England.”

08/12/2020 09:05 GMT — Russia first to approve COVID-19 vaccine
Russia has granted regulatory approval to the first COVID-19 vaccine, which they have named Sputnik V. The news comes after less than 2 months of human tests and before scientists have even begun phase III clinical trials.
According to Putin, “it works quite effectively, forms strong immunity, and, I repeat, it has passed all the necessary checks.” He also told the Russian media that one of his daughters took the vaccine as a volunteer.
The Gamaleya Institute in Moscow developed the vaccine, which will enter mass production by the end of 2020. According to Russian officials, medical personnel will be first to receive the vaccine, which is administered in two doses.
A few weeks later, teachers will be offered the vaccine on a voluntary basis. Officials plan to roll out the vaccine to the wider population in October.
Many officials are concerned that the vaccine has received approval before scientists have conducted enough research. This week, the Association of Clinical Trials Organizations, a trade body who represent the world’s top drug manufacturers in Russia, sent a letter to the health ministry.
In the letter, they urge the government to wait until the end of the phase III trial before approving Sputnik V. In it, they write:
“It is during this phase that the main evidence of a vaccine’s efficacy is collected, as well as information on adverse reactions that could appear in certain groups of patients: people with weakened immunity, people with concomitant diseases, and so forth.”
In an interview, Dr. Anthony Fauci said: “I hope that the Russians have actually definitively proven that the vaccine is safe and effective. I seriously doubt that they’ve done that.”

08/12/2020 09:01 GMT — New Zealand reports new cluster of cases
Today, after 102 days without local transmission, New Zealand reports a cluster of cases. Auckland, the country’s largest city, has returned to lockdown. Officials have registered four new cases of COVID-19 and suspect that another four people may have the disease.
Prime Minister Jacinda Ardern says, “Our plan of mass testing, rapid contact tracing and, of course, our restrictions to stop the chain of transmission has been in full swing in Auckland today.”
According to Director General of Health Ashley Bloomfield, one person with the disease works at a cold storage facility. Officials are working to find out if this could be the source of the outbreak.
Bloomfield explains that “we do know from studies overseas that actually, the virus can survive in some refrigerated environments for quite some time.”

08/11/2020 09:43 GMT — Could mouthwash reduce transmission?
A recent study investigated the possibility that certain mouthwashes could reduce the risk of SARS-CoV-2 transmission. The team tested eight formulations in the laboratory and found that “oral rinsing might reduce the viral load of saliva and could thus lower the transmission of SARS-CoV-2.”
The results appear in The Journal of Infectious Diseases. The authors are quick to note that researchers will need to carry out further tests to understand whether or not the beneficial effect translates to the clinic.
The researchers are also keen to explain that mouthwash cannot fully protect against COVID-19.
As study co-author Toni Meister says, “Gargling with a mouthwash cannot inhibit the production of viruses in the cells, but could reduce the viral load in the short term where the greatest potential for infection comes from, namely in the oral cavity and throat — and this could be useful in certain situations, such as at the dentist or during the medical care of COVID-19 patients.”

In total, New Zealand has recorded 1,570 cases of COVID-19 and 22 deaths. Although their figures are low, Director-General of Health Dr. Ashley Bloomfield explains that “we can’t afford to be complacent.”
He continues, “We have seen overseas how quickly the virus can re-emerge and spread in places where it was previously under control, and we need to be prepared to quickly stamp out any future cases in New Zealand.”

A recent study concludes that the pandemic has led to a significant increase in the prevalence of mental health issues in the United Kingdom. The paper, which appears in the journal American Psychologist, highlights some factors that have influenced people’s ability to cope with the pandemic.
“The COVID-19 pandemic has caused global uncertainty, which has had a direct, detrimental effect on so many people across the U.K. and around the world,” explains lead author Dr. Hannah Rettie, from the University of Bath.
She continues, “People have been unsure when they would see relatives again, job security has been rocked, there is an increased threat to many people’s health, and government guidance is continuously changing, leading to much uncertainty and anxiety.”

08/06/2020 09:25 GMT — Mandatory BCG vaccination may slow spread of COVID-19
A recent study looked for a relationship between COVID-19 rates and bacillus Calmette-Guérin (BCG) vaccination. The scientists conclude that countries that had compulsory BCG vaccination until at least 2000 seem to have built up a degree of “herd immunity” against COVID-19.
The study, which appears in the journal Science Advances, reports how having mandatory BCG vaccination significantly “flattened the curve” of the initial spread of COVID-19.
However, the authors note that researchers will need to continue investigating this effect. Theywrite: “BCG is by no means a magic bullet that assures safety against COVID-19. In all likelihood, there are some societal variables that moderate this effect. This variation must be addressed in future work.”

The global lockdown has caused an unprecedented dip in the number of cases of seasonal flu. The prevalence of other communicable diseases, such as mumps and measles, has also declined. In China, for instance, influenza infections have dropped by 90% since lockdown began.
Similarly, the United Kingdom and Australia have noted significant dips in cases of influenza, and officials in Canada have reported “exceptionally low levels.” South Korea reported an 83% decrease in influenza cases, compared with the same period last year.
Although the decline in influenza prevalence has eased pressure on hospitals, some experts worry that lower numbers of cases might reduce populations’ immunity.
Prof. Ben Marais, an infectious disease expert at the University of Sydney, explains, “It may be that if we don’t have infections this season, there will be more vulnerable people next season, [and] that is definitely something that we will have to carefully monitor. This season passed us by, it seems.”

31/07/2020 10:01 GMT — List of promising drugs against COVID-19 leads to new treatment trial
In a recent study, scientists analyzed a database of around 12,000 existing drugs that have been screened and approved for effectiveness, safety, and availability. From this list, they identified a number of promising compounds — and one, called LAM-002A, is now heading into a phase II clinical trial.
The authors published their list of potential treatments in the journal Nature. A company called AI Therapeutics owns the rights to LAM-002A and, in partnership with researchers at Yale University, they plan to continue studying the drug.
Prof. Murat Gunel, based at Yale and the chief scientific adviser to AI Therapeutics, explains: “LAM-002A holds promise to be a powerful new therapy for COVID-19 patients to prevent progression of the disease, hopefully avoiding the need for hospitalization.”

07/30/2020 10:08 GMT — Promising early results from inhaled drug study
The preliminary results of a recent study show that an inhaled version of interferon-beta reduced breathlessness and increased the chances of recovery in people with COVID-19. The study included data from 101 patients at nine hospitals in the United Kingdom.
According to chief investigator Prof. Tom Wilkinson, “The results confirm our belief that interferon-beta, a widely known drug that, by injection, has been approved for use in a number of other indications, has huge potential as an inhaled drug to be able to restore the lung’s immune response, enhancing protection, accelerating recovery, and countering the impact of SARS-CoV-2.”
Richard Marsden, CEO of Synairgen, the company that developed the new version of interferon-beta, explains that the drug “greatly reduced the number of hospitalized COVID-19 patients who progressed from ‘requiring oxygen’ to ‘requiring ventilation.’” 
He also reports that people who received the drug “were at least twice as likely to recover to the point where their everyday activities were not compromised through having been infected by SARS-CoV-2.”

07/30/2020 10:03 GMT — Seaweed extract may be more effective than remdesivir
The authors of a recent study conclude that extracts from seaweed might be more effective at treating COVID-19 than remdesivir, the current leading antiviral drug for SARS-CoV-2. The results of their study appear in the journal Cell Discovery.  
Heparin, a common blood-thinning agent, is extractable from seaweed. In the current study, the researchers focused on three variants of heparin and two related fucoidans, which naturally occur in seaweed. 
The scientists researched the possibility of using seaweed extract as a SARS-CoV-2 antiviral after studying the shape of the virus particles and how they function to deter a person’s normal antiviral defenses.
“It’s a very complicated mechanism that we quite frankly don’t know all the details about, but we’re getting more information,” explains corresponding author Prof. Jonathan Dordick. “One thing that’s become clear with this study is that the larger the molecule, the better the fit. The more successful compounds are the larger sulfated polysaccharides that offer a greater number of sites on the molecules to trap the virus.”

07/29/2020 09:07 GMT — COVID-19 disruptions could lead to surge in infectious disease deaths
A recent study, which appears in Lancet Global Health, concludes that disruptions to health services caused by the COVID-19 pandemic could lead to significant increases in HIV, tuberculosis, and malaria deaths over the coming years.
Using data modeling, the authors found that over the next 5 years, the number of HIV deaths could increase by 10%, tuberculosis deaths by 20%, and malaria deaths by 36%. Co-lead researcher Prof. Timothy Hallett explains:
“In countries with a high malaria burden and large HIV and TB epidemics, even short-term disruptions could have devastating consequences for the millions of people who depend on programs to control and treat these diseases. However, the knock-on impact of the pandemic could be largely avoided by maintaining core services and continuing preventive measures.”

07/29/2020 09:00 GMT — Modified protein may help ‘speed up vaccine production’
Scientists have created a modified version of the spike protein of SARS-CoV-2. This innovation, they believe, could help speed up vaccine production. They hope that this could make the vaccine available to more people sooner. The researchers have published their findings in the journal Science.
As senior author Jason McLellan explains: “Depending on the type of vaccine, this improved version of the protein could reduce the size of each dose or speed up vaccine production. Either way, it could mean more patients have access to vaccines faster.”

07/28/2020 09:31 GMT — Stroke risk higher for COVID-19 patients who smoke or vape
A recent review concludes that both smoking and vaping could increase the risk of stroke in COVID-19 due to damage to the blood-brain barrier and a higher risk of blood clots. The paper appears in the International Journal of Molecular Sciences.
One of the authors of the review, Luca Cucullo, Ph.D., explains: “COVID-19 seems to have this ability to increase the risk for blood coagulation, as does smoke. This may ultimately translate in higher risk for stroke.”

07/27/2020 14:35 GMT —The first phase III candidate vaccine trial begins in the US amid rising numbers of cases 
Today saw the start of a phase III clinical trial to test whether the experimental COVID-19 vaccine mRNA-1273, which many know as the Moderna vaccine, can prevent COVID-19 in adults.
Meanwhile, the number of confirmed COVID-19 cases and deaths in the United States continue to rise. 
The vaccine, which the biotech company Moderna and the National Institute of Allergy and Infectious Diseases codeveloped, will be given to half of the 30,000 volunteers in the study in two doses. The other half will receive a placebo.
According to the Washington Post, the U.S. had 59,737 new COVID-19 cases on Sunday. South Carolina reported the greatest number of daily deaths and a 41% increase in deaths over the past 7 days.

07/27/2020 12:01 GMT —How has COVID-19 affected suicide ideation in the US? 
A new study by researchers from the University of Arkansas, Fayetteville, AR, highlights how many people are harboring thoughts of suicide during the pandemic. 
The team used questionnaire data from 10,368 adults in the United States and published their work in the journal Suicide and Life-Threatening Behavior.
About 10% and 15% of respondents fell into the categories of moderate and high risk, respectively, as per the Suicide Behavior Questionnaire that the researchers used. 
Some groups of people were disproportionately more likely to fall into the high risk category. These individuals included Black people, Indigenous Americans, Hispanic people, those who were born outside the U.S., and younger people.  
In their discussion, the authors report, “food insecurity appears to be an overwhelming circumstance that, for many, is becoming increasingly difficult to bear.”

07/24/2020 16:10 GMT —Protein innovation could greatly speed up vaccine production 
In the context of promising clinical trial results of new vaccines for COVID-19, researchers from the University of Texas (UT) at Austin have come up with an innovation that may speed up the production of vaccines across the world. 
Most vaccines rely on training the immune system to recognize the key element that makes SARS-CoV-2 so harmful to humans: the spike protein. UT scientists successfully recreated a version of this protein and dubbed it HexaPro.
HexaPro is more stable and resistant to heat, making it easier to transport and store, as well as freeze and thaw several times. Furthermore, when expressed in cells, HexaPro produces almost 10 times more protein than other synthetic spike proteins in use in current vaccines.
“Depending on the type of vaccine, this improved version of the protein could reduce the size of each dose or speed up vaccine production,” says Jason McLellan, senior author of the paper that details the findings. “Either way, it could mean more patients have access to vaccines faster.”

07/24/2020 14:20 GMT — Vaccine candidates show promising results
In the latest feature in our Hope Behind the Headlines series, we look at two much anticipated COVID-19 vaccine clinical trials. One of these candidates is what many people call the Oxford vaccine, while the other comes from a team in China.
Both vaccines use weakened adenoviruses. Many of the trial volunteers experienced side effects, but these were mostly mild. 
In both studies, the majority of volunteers also developed neutralizing antibodies and showed T cell responses. It is not clear how effective these candidates will be in protecting people from COVID-19, but larger studies are ongoing.

07/23/2020 10:24 GMT —Can a combination of antibodies neutralize SARS-CoV-2?
In a study in Nature, a team led by scientists at Vanderbilt University Medical Center in Nashville, TN, investigated antibodies from a couple who had recovered from COVID-19. Two of these antibodies protected mice and macaques from severe COVID-19. 
The antibodies interfered with the viral spike protein binding to the angiotensin converting enzyme 2 (ACE2) receptor. 
The scientists note that other research groups have found that SARS-CoV-2 is able to evolve “escape mutations” to evade a single antibody, but not two antibodies in combination.
It is important to note that scientists have not tested these antibodies in humans yet. But there are planned clinical trials in collaboration with two pharmaceutical companies.

07/22/2020 09:09 GMT — Hydroxychloroquine fails to reduce COVID-19 symptoms
In a recent study, researchers conclude that taking the antimalaria drug hydroxychloroquine shortly after the onset of COVID-19 symptoms does not significantly reduce symptoms or rates of hospitalization. The results appear in the Annals of Internal Medicine.
The authors conclude that “Finding effective therapies against COVID-19 remains critical. Effective treatment of early, outpatient COVID-19 could decrease hospitalizations and, ultimately, morbidity and mortality. Hydroxychloroquine did not substantially reduce symptom severity or prevalence over time in nonhospitalized persons with early COVID-19.”

07/21/2020 11:45 GMT — California experiences largest increase in cases since pandemic began
Yesterday, the state of California reported more than 11,800 new cases of COVID-19. This 1-day increase is the greatest since the beginning of the pandemic. In response, California’s governor, Gavin Newsom, is placing fresh restrictions on businesses across the state.
Bars are closing, and indoor activities in zoos, restaurants, movie theaters, and museums will also cease. In the 30 hardest hit counties, Newsom has also ordered that gyms, churches, and hair salons must close.
California’s previous daily record was 10,861 cases on July 14. To put these numbers into perspective, California’s daily tally exceeds the daily numbers of any European country during the height of the pandemic.
Over the last few days, both Florida and Texas have reported more than 10,000 cases each day.

07/21/2020 10:59 GMT — Delaying COVID-19 emergency measures linked to higher mortality in US
A recent investigation concludes that at the start of the COVID-19 outbreak, each additional day that states delayed declaring an emergency was associated with a 5% increase in mortality. The study appears in the journal Clinical Infectious Diseases.
“To our knowledge, this is the first demonstration of an association between statewide social distancing orders and mortality during COVID-19,” explain the authors. “Our results support early social distancing as a nonpharmaceutical intervention for reducing mortality.”

07/20/2020 15:03 GMT—Oxford vaccine phase I/II results show immune reactions
The adenovirus vector vaccine ChAdOx1 nCoV-19, more widely known as the Oxford vaccine, is safe and produces neutralizing antibodies and T cell responses. 
Writing in The Lancet, the authors explain that mild side effects were common, but that there were no serious adverse events. Taking prophylactic acetaminophen within the first 24 hours of the injection reduced side effects.
All volunteers who received the Oxford vaccine showed T cell responses within 14 days. 
Most participants developed neutralizing antibodies after one dose of the vaccine. Of 10 volunteers who received a booster, all had neutralizing antibodies.

07/17/2020 09:56 GMT — Could zinc protect against COVID-19?
A recent review concludes that zinc might have protective effects against COVID-19 by boosting antiviral immunity and curbing inflammation. However, the authors also explain that the data are not yet sufficient to make recommendations regarding zinc intake and COVID-19.
The authors published their review in theInternational Journal of Molecular Medicine. Lead author Prof. Anatoly Skalny explains that, “According to the current estimates, the risk of zinc deficiency is observed in more than 1.5 billion people in the world.”
He continues: “Given the crucial role of zinc in regulation of immunity, one can propose that its insufficiency may be considered as a risk factor for infectious diseases.”

07/16/2020 10:51 GMT — COVID-19: Doctors round up evidence of damage outside the lungs
Nature Medicine recently published a comprehensive review of COVID-19’s widespread effects on organ systems beyond the lungs. The paper also provides guidelines for managing these diverse effects. Doctors working on the frontline of the COVID-19 outbreak in New York City wrote the paper.
“Physicians need to think of COVID-19 as a multisystem disease,” explains Dr. Aakriti Gupta, who was one of the first cardiology specialists to be deployed to COVID-19 intensive care units at Columbia University Irving Medical Center. 
“There’s a lot of news about clotting, but it’s also important to understand that a substantial proportion of these patients [experience] kidney, heart, and brain damage, and physicians need to treat those conditions along with the respiratory disease.”
MNT covers the new paper in detail here.
07/16/2020 10:01 GMT — COVID-19 associated with spike in broken heart syndrome
Stress cardiomyopathy, which is also known as broken heart syndrome, refers to cardiac dysfunction caused by emotional or physical stress. A new study finds an association between living through the COVID-19 pandemic and an increase in cases of broken heart syndrome.
The scientists compared patients admitted to a hospital for acute coronary syndrome (ACS) before the pandemic with those admitted during the pandemic. They published their findings inJAMA Network Open.
The authors identified “a significant increase in the incidence of stress cardiomyopathy in patients presenting with ACS during the COVID-19 period.”

07/15/2020 08:58 GMT — What was the impact of Sweden’s soft approach to lockdown?
In Sweden, the government enforced a relatively soft lockdown. A recent study investigates how this affected overall death rates. The authors conclude that the approach resulted in fewer deaths than expected but that there were more deaths than in neighboring countries.
The study, which appears in the journal Clinical Infectious Diseases, explains that as of May 15, Sweden had a per capita death rate of 35 in every 100,000 people. This figure is significantly higher than the figures in Denmark (9.3), Finland (5.2), and Norway (4.7).
However, Sweden’s death rate was lower than that of other European countries, including the United Kingdom (51), Spain (58), and Italy (52).

Using laser visualization experiments, a recent study investigates which types of homemade masks are most effective in preventing SARS-CoV-2 transmission. The authors conclude that they should fit snugly and contain multiple layers of quilted fabric.
The new research appears in the journal Physics of Fluids. Lead author Siddhartha Verma explains why the team decided to investigate:
“While there are a few prior studies on the effectiveness of medical-grade equipment, we don’t have a lot of information about the cloth-based coverings that are most accessible to us at present.”
He continues, “Our hope is that the visualizations presented in the paper help convey the rationale behind the recommendations for social distancing and using face masks.”

07/13/2020 09:05 GMT — COVID-19 could directly affect the heart
The authors of a recent stem cell study conclude that SARS-CoV-2 can infect heart cells using the same receptor present in the lungs. The study may help explain the cardiac complications associated with COVID-19. The results appear in the journal Cell Reports Medicine.
The scientists also found that the virus can divide rapidly once it enters heart cells. First study author Dr. Arun Sharma explains:
“We not only uncovered that these stem cell-derived heart cells are susceptible to infection by [the] novel coronavirus, but that the virus can also quickly divide within the heart muscle cells.”

07/09/2020 10:09 GMT — COVID-19: How do we explain ‘happy’ hypoxia?
A recent study concludes that long-established principles of respiratory science could explain the unusual phenomenon of “happy” hypoxia, or silent hypoxemia, in people with COVID-19. The research appears in the American Journal of Respiratory and Critical Care Medicine.
“Happy” hypoxia describes patients who, despite having low blood oxygen levels, appear to function without serious issues or even shortness of breath.
Lead author Dr. Martin J. Tobin explains, “In some instances, the patient is comfortable and using a phone at a point when the physician is about to insert a breathing [endotracheal] tube and connect the patient to a mechanical ventilator, which, while potentially lifesaving, carries its own set of risks.”
In their paper, the authors explain how conventional respiratory science can explain many cases of silent hypoxemia.

07/09/2020 09:35 GMT — SARS-CoV-2 variant does not cause worse symptoms
A recent study finds that a new variant of SARS-CoV-2, which is now the dominant form of the virus, is more infectious in cell cultures. Importantly, though, this variant does not appear to cause more severe cases of COVID-19.
All viruses mutate, and SARS-CoV-2 is no exception. One particular mutation, known as D614G, has raised concerns. From February to April, this variant became the dominant strain, suggesting that the mutation made the virus more infectious.
Bette Korber, Ph.D., the lead author of the study, which appears in the journal Cell, explains, “All over the world, even when local epidemics had many cases of the original form circulating, soon after the D614G variant was introduced into a region, it became the prevalent form.”
The researchers found that the D614G mutation was up to nine times more infectious than the original virus. However, the new variant of SARS-CoV-2 does not appear to be associated with worse outcomes.

07/08/2020 09:13 GMT — WHO consider “possibility of airborne transmission”
Previously, the World Health Organization (WHO) have stated that SARS-CoV-2 spreads primarily through small droplets that an infected person expels in coughs or sneezes. These droplets sink to the ground relatively quickly. However, the WHO are now considering evidence that floating virus particles might also be involved in transmission.
An invited commentary in the journal Clinical Infectious Diseases outlines evidence that suggests this type of airborne spread. A total of 239 scientists reviewed the paper before publication.
Because airborne particles can linger in the air for longer, the scientists urge the WHO to update their guidance, such as the 1 meter physical distance rule. Jose Jimenez, one of the scientists who reviewed the paper, explains:
“We wanted them to acknowledge the evidence. This is definitely not an attack on the WHO. It’s a scientific debate, but we felt we needed to go public because they were refusing to hear the evidence after many conversations with them.”
At a WHO briefing on Tuesday, Benedetta Allegranzi, the WHO’s technical lead for infection prevention and control, said, “The possibility of airborne transmission in public settings — especially in very specific conditions, crowded, closed, poorly ventilated settings that have been described, cannot be ruled out.”
She continued, “However, the evidence needs to be gathered and interpreted, and we continue to support this.”

A new feature from Medical News Today investigates the impact of COVID-19 on the process of medical research. The article covers, among other topics, logistical issues and the loss of jobs and funding in some specialties.
The feature also talks about how journals have shifted focus from other important areas of research to cover coronavirus-related topics.
The Lancet’s editor-in-chief, Richard Horton, recently wrote a comment piece in which he outlined topics that the journal had planned to focus on in 2020 but that had to be shelved to make way for the pandemic. They included child and adolescent health and migration and health. He writes:
“We are not alone in this difficulty. The monumental challenges presented by the Sustainable Development Goals [outlined by the United Nations] have also been pushed to one side by COVID-19. Extreme poverty, gender inequity, safe water and sanitation, and the promotion of peace through health have all become casualties of the pandemic.”

In the United States, COVID-19 is impacting Indigenous communities to a disproportionate degree. In a Special Feature, Medical News Today discuss the mental health effects and challenges that Indigenous people face as a result of the pandemic.
Some regions bring the disparity into stark relief. For instance, in New Mexico, Indigenous Americans make up only 8.8% of the population but account for more than 60% of deaths.
At a teleconference that the Robert Wood Johnson Foundation organized, Dr. Donald Warne, associate dean of diversity, equity, and inclusion at the University of North Dakota School of Medicine & Health Sciences, says, “American Indians are dying of neglect, and we need non-Indian advocates to recognize that there is an Indigenous health crisis in the U.S.”

07/06/2020 10:00 GMT — MMR vaccine could prevent worst symptoms of COVID-19
A recent article, which appears in the journal mBio, suggests that the measles, mumps, and rubella (MMR) vaccine might help fight COVID-19. The authors believe that the vaccine might help reduce the lung inflammation and sepsis associated with the most severe forms of COVID-19.
Earlier research has found that live attenuated vaccines protect against other infections by “training” the immune system in a nonspecific way. Co-author Dr. Paul Fidel Jr. explains, “Live attenuated vaccines seemingly have some nonspecific benefits as well as immunity to the target pathogen.”
The authors propose a clinical trial of the MMR vaccine in high risk healthcare workers.

07/02/2020 09:12 GMT — 61% of Republicans believe ‘the worst is behind us’
A survey of 4,708 adults in the United States, which Pew Research Center conducted, examined how the public are responding to the coronavirus pandemic. The study shows that despite the increasing number of new cases, 61% of Republicans and Republican-leaning independents believe that “the worst is behind us.”
In contrast, only 23% of Democrats and Democratic leaners say that the worst is behind us in regard to COVID-19. The authors note that the report also identifies certain racial differences in the public’s response:
“[C]oncerns over unknowingly spreading the coronavirus have increased8 percentage points among Black Americans (from 64% to 72%) since early April, while decreasingby about the same amount (from 65% to 56%) among white Americans.”

07/02/2020 09:09 GMT — Synthetic antibody could prevent and treat COVID-19
A recent study using a mouse model demonstrates that a synthetic antibody could neutralize SARS-CoV-2. This would help prevent infection as well as treat COVID-19 in those who have it.
A group of scientists from Tulane University, in New Orleans, LA, have developed an antibody that stops SARS-CoV-2 from attaching to the ACE2 receptor and entering cells. They have published their findings on the preprint server bioRxiv.
Lead study author Dr. Jay Kolls explains that “Unlike other agents in development against the virus, this protein is engineered to go to the lungs to neutralize the virus before it can infect lung cells.”

06/30/2020 09:30 GMT — UK city enters lockdown after coronavirus flare-up
As the United Kingdom continues to ease physical distancing, the city of Leicester is set to enter a full lockdown. In the past week, the city has registered 10% of the U.K.’s total COVID-19 cases.
On Monday, Health Secretary Matt Hancock told the House of Commons, “We recommend to people in Leicester, stay at home as much as you can, and we recommend against all but essential travel to, from, and within Leicester.”
According to Hancock, during testing, they identified “a number of positive cases in the under 18s, and that’s why we took the decision with a heavy heart to close schools in Leicester.”
He explained that the number of COVID-19 cases in Leicester was “three times higher than the next highest city.”

06/30/2020 09:26 GMT — Why are some people at greater risk of severe COVID-19?
The authors of a recent study asked why some people are at risk of severe COVID-19 while others are not. By studying interactions between airway cells and immune cells, the scientists identified mechanisms by which the immune system helps SARS-CoV-2 infect more cells.
Corresponding author Prof. Roland Eils explains: “Especially in severely ill patients, we observed that an overreactive immune system drives the destruction of the lung tissue. This might explain why these patients are more severely affected by the infection than patients in whom the immune system reacts appropriately.”
One of the lead authors, Prof. Leif-Erik Sander concludes: “These results suggest that our treatments in COVID-19 patients should not only be directed against the virus itself but should also consider therapies that constrain the immune system, such as those now being used with dexamethasone, possibly even at the onset of the disease to prevent the immune system from overreacting.”

06/29/2020 08:41 GMT — Achieving herd immunity may occur sooner than scientists previously thought
Once a sufficiently large proportion of a population becomes immune to COVID-19, it will no longer be able to spread.This is known as herd immunity. A new study, which uses data modeling, concludes that the threshold for achieving this is significantly lower than scientists had assumed.
The standard model that epidemiologists use to predict herd immunity estimates that the threshold for COVID-19 herd immunity is around 60% of the population.
However, this approach assumes that a population gains immunity following a vaccination program. When the authors of the new study adjusted the model to take into account rates of transmission in different age groups and among people with varying levels of social activity, the threshold for herd immunity dropped to 43%.

06/29/2020 08:37 GMT — Are there links between gut bacteria and COVID-19?
The authors of a recent paper ask whether gut bacteria might influence the risk of contracting the new coronavirus and how they might influence the severity of symptoms. Although there are strands of evidence, they conclude that scientists need to carry out more research.
To date, few researchers have tested the direct impact of gut bacteria on COVID-19. In this recent paper, the authors discuss related studies, which suggest that gut bacteria could play a part. The resulting report appears in the journal Virus Research.
Among other lines of investigation, the authors explain that “several studies have demonstrated that respiratory infections are associated with a change in the composition of the gut microbiota.”
They also write: “The composition of balanced gut microbiota is known to have a major influence on the effectiveness of lung immunity. Germ-free mice, devoid of their intestinal microbiota, have been shown to have impaired pathogen clearance capability in the lung.”

06/26/2020 08:50 GMT — Using nanosponges to neutralize SARS-CoV-2
Microscopic, bio-friendly plastics coated in lung and immune cell membranes could act as a decoy for SARS-CoV-2, neutralizing the virus. These so-called nanosponges might be useful in the fight against a range of viruses. The results appear in the journal Nano Letters.
“It looks like a nanoparticle coated in pieces of cell membrane,” says co-first author Prof. Anna Honko. “The small polymer [droplet] mimics a cell having a membrane around it.” 
In the study, the scientists found that these mimics attracted the virus more effectively than lung cells. Once the virus binds to the nanosponge, it quickly dies.
Next, the researchers need to demonstrate that this technique works in an animal model. In the future, the authors hope that their technology will be available in a nasal spray.
“That would be an easy and safe administration method that should target the appropriate [respiratory] tissues,” says Prof. Honko. “And if you wanted to treat patients that are already intubated, you could deliver it straight into the lung.”

06/26/2020 08:46 GMT — Why COVID-19 ICU patients may experience heart issues
The authors of a recent study conclude that COVID-19 patients in intensive care units (ICU) may be more likely to experience cardiac arrests or arrhythmias due to systemic issues, rather than the virus itself. Their results appear in the journal Heart Rhythm.
Senior author Dr. Rajat Deo explains: “Our findings suggest that noncardiac causes, such as systemic infection, inflammation, and illness, are likely to contribute more to the occurrence of cardiac arrest and arrhythmias than damaged or infected heart cells due to the viral infection.”

In a JAMA viewport article, researchers recommend using a lottery system to allocate scare resources, such as the drug remdesivir, to patients in the hospital with COVID-19. They propose that individual state health departments oversee the lottery systems. 
“Although the purpose of the lottery is to fairly distribute a scarce public resource, a secondary benefit is that the lottery creates randomization, which balances known and unknown confounders across patients who receive or do not receive remdesivir,” the authors argue.

06/24/2020 08:53 GMT — 108 million people in the US cannot work from home
A recent study, which appears in the American Journal of Public Health, finds that 75% of United States workers, which equates to about 108 million people, cannot work from home. These individuals are also more likely to experience layoffs, furloughs, and reductions in hours.
Additionally, these workers are more likely to receive lower pay than those who can work remotely. Study author Marissa Baker explains:
“This pandemic has really exacerbated existing vulnerabilities in American society, with workers most affected by the pandemic and stay-at-home orders being significantly lower paid and now also at increased risk for mental health outcomes associated with job insecurity and displacement, in addition to increased risk of exposure to COVID-19 if they keep going to work.”

The results identified being male, belonging to a racial or ethnic minority group, having overweight, having greater material deprivation, and experiencing household overcrowding as risk factors.
However, cardiometabolic health, vitamin D status, and socioeconomic and behavioral factors did not explain why males and people of ethnic or racial minority groups are more likely to have worse outcomes when they develop COVID-19.

06/23/2020 08:57 GMT — Researchers test arthritis drug against COVID-19
Scientists at The University of Texas Health Science Center at Houston are testing a drug for juvenile rheumatoid arthritis called canakinumab. They hope that it might help prevent “cytokine storm,” a life threatening immune reaction that occurs in COVID-19 patients with pneumonia. 
Canakinumab blocks the cytokine interleukin-1, which is involved in regulating the immune response; it encourages other proteins to respond to threats. The researchers hope that by blocking interleukin-1, the immune response will be muted, preventing the damage caused by an overzealous response.
The researchers are investigating whether canakinumab combined with standard treatment increases survival without requiring invasive mechanical ventilation in patients with COVID-19-induced pneumonia.

06/22/2020 09:49 GMT —Is blood group linked to risk of severe COVID-19?
A new study suggests that people who have blood group A are 45% more likely to need oxygen treatment or ventilation at a hospital with COVID-19 than those with other blood groups, while people who have blood group O are 35% less likely. 
Several researchers have previously proposed that people who have blood group A are more susceptible to infection with the new coronavirus. 
However, not all experts agree. Dr. Sakthivel Vaiyapuri, an associate professor in cardiovascular and venom Pharmacology at the University of Reading in the United Kingdom, commented that while the study was of a high quality, it “doesn’t draw any strong conclusions about how different blood types may make someone susceptible or protective for COVID-19.” 
“People with A blood group should not panic about these results, and at the same time O blood group people should not be relaxed because they may not get this disease. Everyone should follow the guidelines provided by the health authorities and be extremely cautious to protect themselves and others around them,” Dr. Vaiyapuri continued.

In an interview with Prof. John Eason, from the University of Wisconsin-Madison, we examine incarceration as a public health concern in the United States and the toll that it takes on Black communities, especially in the context of the pandemic.
Prof. Eason was highly critical of the healthcare system and the disparities among different communities. He explained that some people’s health actually improves when they are in prison. 
His current research includes studying the extent to which people employed in prisons contribute to the community spread of COVID-19. 
He told us that most of the country’s prisons are located in rural communities with a higher number of Black residents, putting these communities disproportionately at risk during the pandemic.

06/18/2020 09:01 GMT — 88% of US concerned about drug price increases due to COVID-19
A new Gallup poll asks whether people in the U.S. are concerned that the pharmaceutical industry will take advantage of the pandemic to increase drug prices. Overall, 55% were “very concerned” and 33% were “somewhat concerned.” Similarly, 79% were very or somewhat concerned about their health insurance premiums rising. 
Gallup contacted 1,016 adults to complete the survey. The responses also found that “evaluations of how the U.S. has responded to the outbreak itself are tepid.” Just 23% rated the response as “excellent/very good” and 57% rated it as “fair/poor.”
In the Gallup report, the authors write:
“As Americans brace for a potential second wave of coronavirus infections later this year, leaders would be advised to note that it is not just fear of infection or job loss that is causing concern but also fear of increased costs of prescription drugs, insurance premiums and healthcare generally.”

A recent study, which appears in PLOS Medicine, investigates the impact that COVID-19 might have on refugee camps. Using a dynamic model of SARS-CoV-2 transmission, the authors simulated how an outbreak might spread through a large refugee camp.
The authors focused on the Kutupalong-Balukhali Expansion Site in Bangladesh, which is home to more than 600,000 Rohingya refugees from Myanmar. To date, there has been one confirmed COVID-19 death at this site, and 29 people have tested positive for SARS-CoV-2.
The authors conclude that “a COVID-19 epidemic in a refugee settlement may have profound consequences, requiring large increases in healthcare capacity and infrastructure that may exceed what is currently feasible in these settings.”

Individuals with diabetes are more likely to experience severe COVID-19 symptoms. However, in a letter to the New England Journal of Medicine, a panel of 17 diabetes specialists explain that some evidence shows that people may develop diabetes for the first time as a result of COVID-19.
One of the authors of the letter, Prof. Francesco Rubino, explains, “Diabetes is one of the most prevalent chronic diseases, and we are now realizing the consequences of the inevitable clash between two pandemics.”
He continues, “Given the short period of human contact with this new coronavirus, the exact mechanism by which the virus influences glucose metabolism is still unclear, and we don’t know whether the acute manifestation of diabetes in these patients represents classic type 1, type 2, or possibly a new form of diabetes.”

06/17/2020 14:38 GMT — Children are less likely to get COVID-19, say researchers
A new study estimates that children are only half as likely to get COVID-19 as adults over the age of 20. The research also proposes that only 21% of children aged 10–19 show symptoms when they have the new coronavirus.
In adults over the age of 70 who have the virus, 69% show symptoms, according to the data model that scientists from the London School of Hygiene & Tropical Medicine in the United Kingdom describe in Nature Medicine. 
The authors used data from six different countries to build their model but acknowledge that their study has some limitations. 
Prof. Mark Woolhouse from the University of Edinburgh in the U.K., who was not involved in the study, comments that “[t]his evidence suggests interventions aimed at children, such as school closures, might have a relatively small impact on reducing transmission of SARS-CoV-2.”

06/17/2020 09:31 GMT —How many people with coronavirus remain asymptomatic?
A review of several COVID-19 study cohorts indicates that around 40–45% of people who contract the new coronavirus do not show symptoms. Whether they pass on the virus is not entirely clear, but the study authors suggest that it is likely. 
The researchers, from the Scripps Research Translational Institute, in La Jolla, CA, assessed data from 16 study cohorts, including nursing homes, homeless shelters, prisons, and cruise ships, to pinpoint the proportion of people who remain asymptomatic after contracting the new coronavirus.
While the numbers varied among the studies, the team estimate the proportion of asymptomatic people with the infection to be 40–45%. “Asymptomatic persons can transmit SARS-CoV-2 to others for an extended period, perhaps longer than 14 days,” they write, although data on silent transmission is limited.
They also suggest that people who remain asymptomatic may nevertheless experience damage to their lungs as a result of the virus.

Clinical trial data from the United Kingdom show that dexamethasone can reduce deaths among COVID-19 patients on ventilators by one-third. The researchers have not yet published the data, but experts have welcomed the announcement. Dexamethasone is widely available and inexpensive. 
Scientists from the University of Oxford in the U.K. announced the preliminary results from the dexamethasone arm of their RECOVERY trial, which set out to test six different treatments for COVID-19. 
The clinical trial team treated 2,104 patients with 6 milligrams of dexamethasone once per day for 10 days and compared the results with those of 4,321 patients who received standard care without the drug. 
Dexamethasone is a steroid that doctors commonly prescribe to treat inflammation, allergic reactions, and immune-mediated conditions, such as rheumatoid arthritis. 
The overall mortality rate in the dexamethasone group was 17% lower than in the control group. More specifically, the 28-day mortality rate in patients requiring ventilation was 41% in those who received standard care and one-third lower in the group on dexamethasone. For patients on oxygen therapy who received standard care, the mortality rate was 25%, which reduced by one-fifth in the dexamethasone group. 
“Based on these results, one death would be prevented by treatment of around eight ventilated patients or around 25 patients requiring oxygen alone,” the chief investigators explain in the press release. “Given the public health importance of these results, we are now working to publish the full details as soon as possible.”
Several experts have reacted positively to the news.
