Technical Abstract: The recent introduction of highly pathogenic avian influenza virus (HPAIV) H5N8 into Europe and North America poses significant risks to poultry industries and wildlife populations and warrants continued and heightened vigilance. First discovered in South Korean poultry and wild birds in early 2014, this virus apparently arose from reassortment events in China between HPAIV H5N1 (clade 220.127.116.11) and several low pathogenic viruses. The H5N8 virus was subsequently found in Russian waterfowl in September 2014 and has since been found in poultry and wild birds in Europe (Netherlands, Germany, Italy, Great Britain), Taiwan, Japan, Canada (British Columbia), and western USA (Washington, Oregon, California, Idaho, Utah). Providing resources for robust surveillance programs in wild birds and poultry, modeling of HPAIV infected wild bird movements, and experimental research studies will provide the knowledge required for intelligent agricultural policy making, wildlife management, and public health decisions.
