Researchers compared SARS-CoV-2 with the related bat coronavirus RaTG13 and studied how viral proteins interacted with immune proteins in bat and human lung cells. A protein called OrfB9 emerged as ...

Viruses closely related to the deadly MERS coronavirus are lurking in bats and one group, known as HKU5, may be just one mutation away from making the jump to humans. A new study reveals how these ...

A single genetic mutation might explain why West Nile virus has, within a decade, switched from causing relatively mild infections in humans to outbreaks of deadly encephalitis. The virus, which can ...

Hopefully, you have already received your seasonal flu vaccine this year. These shots are highly effective at preventing illness, ultimately lowering the spread of the virus throughout the population.

I LEARNED a lot about pandemics and epidemics during Covid-19 as it was the first real epidemic that affected me, and I ...

Some viruses mutate more rapidly than others. Learn more about why that is and what that means for your health. Have you ever wondered why you have to get a flu shot every year, but some vaccines are ...

In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

Influenza A virus particles strategically adapt their shape—to become either spheres or larger filaments—to favor their ability to infect cells depending on environmental conditions, according to a ...
