Avian influenza viruses typically require several mutations to adapt and spread among humans, but what happens when just one change can increase the risk of becoming a pandemic virus? A recent study ...

The avian flu virus isolated from a hospitalized teenager in Vancouver has mutations in key areas that could help the virus spread more easily in humans, scientists say. There is no indication that ...

A 13-year-old girl in British Columbia who was hospitalized with bird flu for several weeks late last year harbored a mutated version of the virus, according to a report published this week in the New ...

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 ...

Viruses are masters at disguise. When they are pushed too far by our immune system, they send new virus variants into play that are no longer recognized by immune cells. They escape our immune system ...

This month’s story comes from the Bloom lab using their signature deep mutational scanning technique to identify mutations in the surface protein of Lassa virus -called glycoprotein- that escape ...
