Some worry a treatment that kills SARS-CoV-2 by helping it mutate could spawn a super virus. New research weighs in on its "evolutionary safety."

When administered at a human effect size-equivalent dose, molnupiravir efficiently blocked transmission of SARS-CoV-2 in ferrets.

Researchers still don’t know how well BA.2.86 will evade immunity or whether it will cause more severe disease than its predecessors.

William Hanage, an associate professor of epidemiology, talks about hybrid protection, vulnerability of older people, and the wisdom of Taylor Swift.

The new approach could lead to intranasal vaccines for Covid-19 and other respiratory diseases.

Researchers have begun tracking the rates of inter-species COVID transmission in hopes to gain insight into ongoing trajectory of the virus.

New research into baby gut bacteria and the pandemic has implications for physical and mental health at life’s early stages.

We all want to move on from COVID-19. But it's not so simple, says Angela Branche, an infectious disease expert.

A new AI-powered triage platform can predict patient disease severity and length of hospitalization during a viral outbreak, researchers say.
