H3N8
Introduction
H3N8 is a subtype of the species Influenza A virus (sometimes called bird flu virus). H3N8 is now endemic in birds, horses and dogs.
H3N8 is suspected of causing a human pandemic in either 1889 or 1900. Sources differ; some say the 1889 pandemic was caused H2N2. The experts also differ on exactly how sure we can be that either were involved.[1]
It was the subtype that was responsible for over one-forth of the flu infections in wild ducks in a 1997 study.[2]
