WILD BIRD HIGHLY PATHOGENIC AVIAN INFLUENZA CASES IN THE UNITED STATES a LINE COLLECTION DATE SPECIES COUNTY STATE SUBTYPE b CONFIRMATION DATE COLLECTING AGENCY COLLECTION STRATEGY c 1 07-31-2015 Mallard Davis UT EA H5 d 08-21-2015 Utah DWR L a Avian H5 influenza (H5N8) originating from Eurasia (EA) spread rapidly along wild bird migratory pathways during 2014. Introduction of this virus into the Pacific Flyway sometime during 2014 has allowed mixing with North American (AM) origin viruses and generated new (novel) combinations with genes from both EA and AM origin (or “reassortant” viruses). These findings are not unexpected as the EA-H5 viruses continue to circulate in the flyways. This group of EA-H5 viruses is highly pathogenic in poultry. The ‘novel EA/AM H5N1’ is different from the ‘Asian HPAI H5N1’ and is a mixture of Eurasian and low pathogenic North American origin viruses. b EA = Eurasian; AM=North American; the EA-H5 (2.3.4.4) are highly pathogenic to poultry c M = morbidity/mortality; H = hunter harvest ; L = live bird released; A = agency harvested d Sequencing was unsuccessful and no virus was isolated, but the specimen was positive by the H5 (icA) molecular assay which targets the Eurasian H5 clade 2.3.4.4 viruses first detected in the US in December 2014. e Cases posted in most recent update. f American Oceania flyway consists of Hawaii, Guam, Marshall Islands, and American Samoa.
