EPIDEMIOLOGICAL COMMENTS
The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Animal Health and Wildlife Officials, are conducting comprehensive epidemiological investigations and enhanced surveillance in response to the HPAI H5N1 related events. Affected population counts are based on estimated inventories from the date the outbreak was first reported to the World Organisation for Animal Health. HPAI events are now closed and control areas have been released in the following States: Alabama, Alaska, Arkansas, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Mississippi, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Tennessee, Utah, Virginia, Washington and Wisconsin. These States have not had any recent HPAI events and have demonstrated: • Required surveillance in the State and control areas has been completed with negative results for HPAI. As a precaution, additional enhanced surveillance may continue in the State and area. • Depopulation of infected premises has been completed and appropriate disposal was implemented or completed. • Cleaning and disinfection of the infected premises has been completed (including, but not limited to, outside areas of premises, equipment, trucks, and other fomites). Note (26/10/2022): After reassessment by field investigators, outbreak OB_107904 has been designated as non-poultry premises and subsequently removed from this event.
