Epidemiology

  • Contact with wild species
Epidemiological comments All HPAI H5N2 outbreaks in all affected States (Arkansas, California, Idaho, Indiana, Iowa, Kansas, Minnesota, Missouri, Montana, Nebraska, North Dakota, Oregon, South Dakota, Washington, and Wisconsin) are now final, closed, and resolved. The last positive detection of HPAI H5N2 in poultry was made on June 18, 2015. In addition to having no further HPAI detections, all States affected with HPAI (listed above) have met the following: - Mandatory surveillance in the State and control areas has been completed with negative results for HPAI. As a precaution, additional enhanced surveillance and procedures may continue in the State and area. - Depopulation of all infected premises has been completed and appropriate disposal was completed. - Cleaning and disinfection of the infected premises (including, but not limited to, outside areas, equipment, trucks, and other fomites). - No HPAI detections through wild bird surveillance have been made within the past 3 months. The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Departments of Agriculture and Wildlife, and industry, continue to conduct thorough surveillance nationally for avian influenza virus through the National Poultry Improvement Plan (NPIP), Live Bird Market System, and wild bird surveillance programs, as well as completely investigate any suspected avian influenza virus event. No HPAI has been detected in poultry over 5 months. Each outbreak has been closed after the requested three-month period of stamping out, disinfection and surveillance. The HPAI event in the United States is considered CLOSED. In accordance with the World Organisation for Animal Health (OIE) Terrestrial Animal Health Code Chapter 10.4 (Articles 10.4.3 and 10.4.4), the United States has completely fulfilled the necessary actions and surveillance requirements to again self-declare itself free from HPAI.
