Ferrets not susceptible to SARS-CoV-2 infection

A recent study by scientists at the Cummings School of Veterinary Medicine at Tufts University has revealed that ferrets are not susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection even if they are directly exposed to symptomatic coronavirus disease 2019 (COVID-19) patients for a prolonged time.

Assessment of SARS-CoV-2 transmission on an airplane

As the COVID-19 pandemic continues to spread across the world, air travel restrictions are slowly being eased in some regions. Now, a new report published in the JAMA Network Open journal in August 2020 shows that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can spread among passengers on international flights unless proper precautions are taken.

No evidence of active SARS-CoV-2 in breastmilk of infected women

A recent study published in the journal JAMA in August 2020 suggests that SARS-CoV-2 RNA does not represent replication-competent virus and that breast milk may not be a source of infection for infants.

Websites selling home-based COVID-19 testing kits providing inadequate or misleading information

In the UK and US, many websites are selling direct to user self-sampling and testing kits to detect SARS-CoV-2. Recently, a cross-sectional observational study was carried out to check the completeness and accuracy of information provided by these websites.

Whey protein from human breastmilk inhibits SARS-CoV-2 infection

Many scientists have reported the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on pregnancy and the virus has been detected in breastmilk. Now a new study published on the preprint server bioRxiv* in August 2020 shows that whey protein in human breastmilk efficiently prevents infection with SARS-CoV-2 as well as post-entry viral replication.

Genomics study shows multiple and diverse SARS-CoV-2 introductions in the US capital region

A recent study led by the researchers from Johns Hopkins University reveals multiple and diverse introductions of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States National Capital Region during the initial phase of coronavirus disease 2019 (COVID-19) pandemic. The study is currently available on the medRxiv* preprint server.

Potential inhibitors of SARS-CoV-2 identified

Now, a new study published on the preprint server bioRxiv in August 2020 reports the discovery of two inhibitors of the helicase enzyme, which is essential for viral replication and the most highly conserved non-structural coronavirus (CoV) protein.

SARS-CoV-2 viral load predicts risk of death

As the coronavirus pandemic evolved, there have been many developments in testing for the SARS-CoV-2 viral load in patients. Now, a team of researchers at the Icahn School of Medicine at Mount Sinai, New York, has found that the SARS-CoV-2 viral load can predict mortality in patients with coronavirus disease (COVID-19).
