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.

Study: SARS-CoV-2 can infect human neural progenitor cells and brain organoids

SARS-CoV-2 can infect human neural progenitor cells and brain organoids, as shown by researchers from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences and their collaborators from The University of Hong Kong (HKU).

COVID specific IgA monoclonal antibodies may provide effective immunity against coronavirus

A new study by researchers at MassBiologics of UMass Medical School published in Nature Communications suggests that COVID specific IgA monoclonal antibodies may provide effective immunity in the respiratory system against the novel coronavirus - a potentially critical feature of an effective vaccine.

World's first confirmed case of SARS-CoV-2 re-infection

A team of researchers at the University of Hong Kong said that they have proven that a 33-year-old man was infected by the SARS-CoV-2 virus for a second time. The man was discharged from a hospital in April but contracted the infection again after returning from Spain via the United Kingdom in August.

Relative humidity could play a role in transmission of SARS-CoV-2 indoors

A new study has explored the role of relative humidity in the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from person to person indoors. The study titled, “An Overview on the Role of Relative Humidity in Airborne Transmission of SARS-CoV-2 in Indoor Environments,” is published in the latest issue of the journal Aerosol and Air Quality Research.
