Researchers discovered why bird flu can survive temperatures that stop human flu in its tracks. A key gene, PB1, gives avian viruses the ability to replicate even at fever-level heat. Mice experiments ...

Scientists have discovered that avian influenza viruses have a gene that makes them incredibly resistant to heat, rendering our body's natural defense system – fever – powerless in fighting infection.

Just as we thought we had a handle on how to manage the spread of bird flu, a recent study has turned the usual safety playbooks on their head. For years, we’ve relied on the idea that heat is the ...

Bird flu cases are increasing, and a new review suggests the virus might spread between people without causing symptoms. But with limited surveillance and major gaps in data and reporting, the scope ...
