Antiviral inhibitor DDX42 shows broad activity against Chikungunya, HIV and SARS-CoV-2

By exploiting type 1 interferon's ability to foster an antagonistic cellular environment for viral replication, a research group from France pinpointed DEAD-box RNA helicase DDX42 as an intrinsic inhibitor of HIV, but also other pathogenic viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Chikungunya virus.

Researchers test effectiveness of different fabric masks at filtering particles

A team of researchers have tested everything from t-shirts and socks to jeans and vacuum bags to determine what type of mask material is most effective at trapping the ultrafine particles which may contain viruses such as SARS-CoV-2, the virus which causes COVID-19.

Research shows why certain people infected with COVID-19 show no symptoms

Researchers worldwide have been surprised to see that individuals can be infected with the SARS-CoV-2 virus - the virus that produces COVID-19 - without showing symptoms. Since these individuals expose others to infection without knowing it, it is important to find an explanation and hopefully a solution to this.

Majority of people infected with mild-to-moderate COVID 19 mount robust antibody response

The vast majority of individuals infected with mild-to-moderate COVID 19 mount a robust antibody response that is relatively stable for at least five months, according to research conducted at the Icahn School of Medicine at Mount Sinai and published October 28, in the journal Science.

Researchers estimate prevalence of SARS-CoV-2 antibodies among adults in orange county

Testing a representative sample of Orange County residents for a wide range of coronavirus antibodies, University of California, Irvine researchers found that 11.5 percent of them have antibodies for COVID-19, in contrast to previous estimates of less than 2 percent.

Mouth may be primary route of SARS-CoV-2 infection and transmission

A new study published on the preprint server medRxiv in October 2020 shows that the virus also multiplies robustly in the oral cavity, indicating that saliva plays a role in viral transmission.

Travel surges before lockdown undermine the SARS-CoV-2 containment effort

Recently, researchers from the Harvard T.H. Chan School of Public Health, Boston; the University of Illinois at Urbana Champaign; and the University of California, USA, assessed the impact of the announcement and implementation of restrictions such as lockdowns on mobility patterns of humans.

COVID-19 mortality rate declines significantly in Sweden

A new observational study by Swedish researchers shows a significant decline in death rates among hospitalized patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their study titled, "Decline in mortality among hospitalized covid-19 patients in Sweden: a nationwide observational study," was released online as a preprint on the medRxiv* server.

Genome-wide CRISPR screens reveal resistance and sensitization mechanisms of drugs used in COVID-19

By leveraging nucleotide triphosphate analog-induced cell death, Chinese researchers unveiled genes that affect the import, export, and metabolism of pervasively used antiviral drugs in the treatment of coronavirus disease (COVID-19). This exciting study is currently available on the bioRxiv* preprint server.

Study: Nearly 17% of recovered COVID-19 patients could still carry the virus

A new study in the American Journal of Preventive Medicine, published by Elsevier, presents new data that address important questions pertaining to the containment of the coronavirus pandemic: When should COVID-19 quarantine really end and which continuing symptoms may be more indicative of a positive test in recovered patients?
