Seroprevalence meta-analysis predicts 643 million already infected by SARS-CoV-2 globally

A recent systematic review and meta-analysis conducted by a team of international scientists reveal low seroprevalence of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the general population.

Detectable SARS-CoV-2 antibodies 120 days post-infection in Chicago case study

In a recent study, a team of researchers at Northwestern University, USA, had found that nearly 20 percent seroprevalence in the United States metropolitan site, Chicago, over the summer, during a period when lockdown restrictions were eased. They found that three-quarters of seropositive individuals retained detectable antibodies for at least 120 days or four months.

Peptide-conjugated morpholino oligomers effectively inhibit SARS-CoV-2 in vero cells

The hunt for antivirals has reached an unprecedented pace in light of the coronavirus 2019 (COVID-19) pandemic. The causal agent for this disease – severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – has already infected over 52 million people worldwide, and has subsequently claimed over 1.3 million lives. However, among the innumerable promising drug candidates that help battle the virus and mitigate its damage, none have yet made it to the clinic.

"Cat's claw" extract inhibits replication of SARS-CoV-2 in vitro

Researchers in Columbia and Peru have shown that Uncaria tomentosa – a woody vine native to South America known of as "Cat's claw" – exerts in vitro antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).
