Technical Abstract: Avian influenza virus is naturally found in wild birds, primarily waterfowl, but the virus may also be found in poultry. The virus can be found in different pathotypes; low pathogenic avian influenza causes a localized infection often with little clinical disease, the highly pathogenic form of the virus causes a systemic disease with high mortality in chickens. The virus virulent in one species may not cause disease in another species, although it may infect both species. The low pathogenic viruses of the H5 and H7 subtypes can mutate to the virulent form of the virus, and therefore low pathogenic H5 and H7 viruses as well as all highly pathogenic avian influenza viruses are reportable to the World Organization for Animal Health. Currently the biggest ongoing outbreak of highly pathogenic avian influenza is the Asian H5N1 virus that is endemic in at least 5 different countries. Other recent outbreaks of H7 avian influenza has occurred in Italy, Australia, and Mexico. Constant vigilance is required to identify poultry infections with avian influenza and to quickly eradicate them to prevent further spread.
