The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus ...

These new insights into the influenza replication complex can be used to study polymerase mutations in other similar strains of the avian influenza virus. It is therefore possible to use the structure ...

It’s the latest in a string of deaths and infections in and around Chicago. Outbreaks of the virus, also called H5N1 or avian flu, have decimated poultry flocks and infected cattle herds nationwide.

Flu viruses that typically infect birds have an affinity for latching on to the particular shape of a receptor commonly found in the guts of avian species. Human influenza viruses, on the other ...

This bird flu, which scientists call highly pathogenic avian influenza, or H5N1, is already at panzootic—animal pandemic—status, ... Influenza viruses share the same basic structure, ...

Influenza, in general, small changes in the genetic structure of the virus can lead to the emergence of new subvariants, and variants and strains, kind of similar to what we see with coronavirus ...

H5N9 is a highly pathogenic avian flu (or bird flu) virus that bears some structural similarities to H5N1. "Low pathogenic" ...

While there have been no recent cases of avian flu in Utah's poultry or cattle, Arizona and Idaho have ongoing outbreaks.

Single bird flu mutation could let it latch easily to human cells, study finds. The potential mutation would allow the virus to hitch itself to a protein on the surface of our cells, known as the ...

Historically, the avian flu has had a high mortality rate. Between 1997 and 2021, there were 833 cases reported in about 20 countries. In about half of those cases, the people infected with avian ...
