Canadian researchers identify a highly mutated variant of the virus in white-tailed deer and link it to a human COVID-19 case in the region—though they emphasize that the infection risk to people is low.

Thousands of animals have had their shot already. How many more really need it?

Researchers report what appears to be the second case of a person’s immune system clearing the virus on its own.

Researchers used sequencing data and phenotypic traits to predict which of 5,400 species were most likely to be susceptible to contracting and spreading the virus back to humans.

Two viruses from dogs and pigs were isolated from human patients, but neither was proven to cause severe disease or to transmit to other people.

Genetic analyses suggest that the virus came from a patient who survived the 2013–2016 West African outbreak.

A handful of factors tip the scales in making a virus more likely to trigger a disruptive global outbreak. Right now, scientists tend to rank influenza, coronaviruses, and Nipah virus as the biggest threats.

A coronavirus has been commanding the headlines for months, but strains of influenza and paramyxovirus are extremely dangerous pathogens that could spark outbreaks.

The bat version of the STING protein helps dampen the mammals' immune response to infection, researchers have found.

Curing HIV means finding and eradicating viruses still lurking in the shadows.

Oxford researcher John Frater explains the strategy of targeting viral reservoirs to beat HIV.
