Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus, which primarily affects birds but can sometimes affect mammals including humans. [1] Wild aquatic birds are the primary host of the influenza A virus, which is enzootic (continually present) in many bird populations.
Scientists are warning about the continued transmission of dangerous H5N1 bird flu, saying that the virus is more widespread than believed. “We are in a soup of virus.I mean, there’s virus ...
H5 N2 is a subtype of the species Influenzavirus A (avian influenza virus or bird flu virus). The subtype infects a wide variety of birds, including chickens, ducks, turkeys, falcons, and ostriches.

H5N6 is a subtype of the species Influenza A virus (sometimes called bird flu virus). Infected birds shed the virus in their saliva, mucus, and feces. The virus was first detected in poultry in 2013, since then spreading among wild bird populations and poultry around the world. Humans can be infected through unprotected contact with infected ...
The bird flu virus isn’t as prevalent in the upper airways, which seems to make it less transmissible among humans, Sutton says. That’s not to say respiratory spread is impossible, though.
The strain called bird flu is an influenza A virus and gets its name because wild birds such as gulls, ducks geese and other waterfowl act as hosts for the virus.
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus, which causes influenza (flu), predominantly in birds. It is enzootic (maintained in the population) in many bird populations, and also panzootic (affecting animals of many species over a wide area). [1]
Bird flu has been killing birds for decades.Strains of the virus have been detected in birds since 1996, with serious outbreaks in 2004 and 2005. But the current outbreak is the worst Avian flu in ...
