Study shows furin cleavage site is crucial for SARS-CoV-2 replication

In a recent bioRxiv* preprint paper, researchers from the United States demonstrate the pivotal role the furin cleavage site insertion in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein plays in viral replication and pathogenesis – highlighting, in turn, the need for mutation monitoring when developing therapeutics and vaccines.

Evidence of SARS-CoV-2 coronavirus particles in heart tissue

Researchers in Milan, Italy, have identified the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the heart tissue of deceased coronavirus disease 2019 (COVID-19) patients who had died from respiratory failure, without showing any signs of cardiac involvement.

Two viral gene targets needed in SARS-CoV-2 detection by PCR, say researchers

Researchers at the Chan Zuckerberg Biohub, San Francisco, and collaborators have warned against only targeting one viral gene when carrying out reverse transcriptase-polymerase chain reaction (RT-PCR) testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

First lethal mouse model of SARS-CoV-2 developed

Army scientists have developed the first lethal mouse model of SARS-CoV-2, the virus that causes COVID-19, using mice that were genetically engineered to express the human ACE2 gene--a key mechanism by which the virus enters human cells.

Scientists say insect repellent kills the SARS-CoV-2 coronavirus on surfaces

Now, a team of scientists at Britain's Defence Science and Technology Laboratory (DSTL) has shared preliminary findings of their research, showing that a product in insect repellent can kill the SARS-CoV-2 virus.

Coronavirus can spread through drain pipes in bathrooms, study suggests

Now, a new study reveals that the virus may spread via aerosols through drain pipes in bathrooms, after scientists examined an abandoned apartment in Guangzhou, China. The findings add to the body of evidence suggesting the virus is transmissible via aerosols.

Obesity ups COVID-19 death risk by 48 percent

Now, a new study by researchers from the University of North Carolina (UNC), the World Bank, and Saudi Health Council, shows that obesity increases the risk of dying from COVID-19 by as much as 48 percent, hinting that a vaccine against the virus could be less effective in obese people.

More evidence mask wearing works to contain COVID-19 spread

A team of American researchers has looked at the effects of wearing face masks and the prevention of the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between individuals. As of today, over 5.8 million people in the USA have been infected with the virus. This new study titled, “Mask Wearing and Control of SARS-CoV-2 Transmission in the United States,” is published on the preprint server medRxiv*.

Global survey reveals hesitancy in potential acceptance of a COVID-19 vaccine

A recent study, currently available on the medRxiv* preprint server, shows that willingness to vaccinate against coronavirus disease (COVID-19) is insufficient in 19 countries that were surveyed – highlighting the need for targeted interventions to increase and sustain public acceptance of an incoming COVID-19 vaccine.

Study suggests memory B cells persist following COVID-19 recovery

Researchers at Tel Aviv University in Israel have gained valuable insights into the serological and B cell response to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Researchers shed light on Boston's SARS-CoV-2 superspreading event

Researchers in the United States have shown that failure to prevent the importation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into Massachusetts led to superspreading that drastically altered the course of the epidemic and amplified the outbreak in this major urban area.

Estradiol appears to help in female SARS-CoV-2 infection

A new study published on the preprint server medRxiv in August 2020 shows that the risk of infection is high for pre-menopausal women but the risk of death is much higher for men in the same age group and throws light on the protective nature of estradiol therapy in post-menopausal women.

Monoclonal antibodies may be a better choice than convalescent plasma for treating COVID-19

A team of researchers from the Netherlands demonstrated that prophylactic treatment with a high dose of human convalescent plasma or by using concentrated monoclonal antibodies could protect against disease following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in an animal model. However, no protective effect was observed with a ten-fold lower dose of convalescent plasma. The results are currently available on the bioRxiv* preprint server.

Humidity (not temperature) influences SARS‐CoV‐2 transmission

A recent study conducted in New South Wales, Australia, demonstrates that there is an inverse relationship between relative humidity and transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study is published in the journal Transboundary and Emerging Diseases.

Assessing the risk of COVID-19 outbreaks once schools reopen

A study conducted by researchers at the London School Of Hygiene and Tropical Medicine, University of Edinburgh, and Leiden University, suggests that only reopening schools to specific age groups would reduce the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) being transmitted between schools and subsequently households.

High SARS-CoV-2 antibody seroprevalence, low mortality at Austrian COVID-19 epicenter

Now, a new study reported on the preprint server medRxiv* in August 2020 describes a high seroprevalence in an Austrian ski resort, which is considered to be the source of the European outbreak.

Inconsistent implementation of COVID-19 control has dire consequences

Researchers in the United States have conducted a study highlighting the potential unintended consequences of implementing coronavirus disease 2019 (COVID-19) control policies in an inconsistent, patchy manner.
