H5N1 VIRUS
Influenza A virus subtype H5N1, also known as A(H5N1) or simply H5N1,
is a subtype of the Influenza A virus which can cause illness in
humans and many other animal species. A bird-adapted strain of H5N1,
called HPAI A(H5N1) for "highly pathogenic avian influenza virus of
type A of subtype H5N1", is the causative agent of H5N1 flu, commonly
known as "avian influenza" or "bird flu". It is endemic in many bird
populations, especially in Southeast Asia. One strain of HPAI A(H5N1)
is spreading globally after first appearing in Asia. It is epizootic
(an epidemic in nonhumans) and panzootic (affecting animals of many
species, especially over a wide area), killing tens of millions of
birds and spurring the culling of hundreds of millions of others to
stem its spread. Most mentions of "bird flu" and H5N1 in the media
refer to this strain.
