Besides HPAI and LPAI, is avian influenza divided into other groupings?
A. Yes, there are 144 different characterizations of the virus based on two groups of proteins found on the surface of the virus. One group is the hemagglutinin proteins (H), of which there are 16 different types (H1-H16); the other group is the neuraminidase proteins (N), of which there are 9 different types (N1-N9). The virus detected in several Asian and European countries is an H5N1 type of highly pathogenic Avian Influenza virus.
