The latest wild APHIS wild bird update has added four more confirmed cases, including H5N2 in a red-tailed hawk in Benton County, Washington collected last year, 1 day after collection of H5N2 samples in the index farm in Benton County

Epidemiological comments The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Departments of Agriculture and Wildlife, are continuing to conduct a comprehensive epidemiological investigation and enhanced surveillance (including wild bird surveillance of hunter harvested birds) in response to the HPAI H5N2 wild bird related event. All backyard premises have been quarantined and enhanced active surveillance is being conducted in and around the backyard flocks. To date, all enhanced surveillance testing around the affected premises has been negative for avian influenza. Novel avian influenza virus of Eurasian origin (EA-H5N8 clade 2.3.4.4) spread rapidly along wild bird migratory pathways during 2014. Introduction of this EA-H5N8 virus into the Pacific Flyway sometime during 2014 has allowed mixing with North American (AM) lineage viruses and generated new combinations with genes from both EA and AM origin (or “reassortant” viruses) such as this EA/AM H5N2-reassortant detected in Canada and the US. These findings are not unexpected as the EA-H5N8 virus continues to circulate. The EA-H5 clade 2.3.4.4 viruses are highly pathogenic for poultry. The HPAI EA/AM H5N2-reassortant virus has NOT been found in commercial poultry anywhere in the United States.
