Technical Abstract: Outbreaks continue of H5N1 high pathogenicity avian influenza (HPAI) in Asia during 2005. Reports of additional poultry cases have occurred in China, Indonesia, Vietnam and Thailand. The virus is now endemic in smallholder and scavenger poultry many parts of Asia where infections in domestic ducks are as high as 70%. New outbreak countries have included Russia, Mongolia, Kazakstan, Turkey, Croatia, and Romania. An infected parrot in quarantine was reported in the United Kingdom. The major development has been the infection of some migratory bird species with mortality. In addition, outbreaks in poultry within some countries have been linked to migratory bird movements. The majority of the poultry infections have involved backyard or outdoor reared chickens, turkeys and ducks. The threat of introduction of the virus to the USA has increased with the wider distribution of the virus in Asia and Europe. Natural and regulatory barriers have made introduction of very low risk through migratory birds, legal commerce and human movement. However, illegal commerce in live birds (captive wild and poultry) or untreated products pose the greatest threat for introduction. The virus is labile and easily inactivated by heat. Cooking at a minimal temperature of 70C will inactivate virus in meat in less than 1 minute.
