Impact of emergence of avian influenza in North America and preventative measures. In: Proceedings of the 65th Western Poultry Disease Conference, April 25-27, 2016, Vancouver, British Columbia, Canada. p. 265-266. Interpretive Summary: Technical Abstract: Since 1959, the world has experienced 39 highly pathogenic avian influenza (HPAI) epizootics with the largest beginning in 1996 in China that spread to affect 70 countries in Asia, Europe and Africa, and recently North America. Eurasian H5N8 and reassortant H5N2 HPAI viruses were identified in USA. These H5 HPAI viruses spread through the Pacific Flyway and to the Midwest USA. The infected premises in Western and initial premises in Midwestern USA were point source introductions from wild birds, while most cases in the Midwest had secondary spread from common sources because the initial viruses were waterfowl adapted but later were adapted to gallinaceous poultry. |
