The USDA has confirmed highly pathogenic avian influenza (HPAI) in one commercial flock and one backyard flock in Kansas. Nearly 3 million birds across the United States have been affected in the last 30 days.
Why it matters
Waterfowl carry the virus and can transmit it to poultry flocks as they migrate south at this time of year, and migration season raises the risk of further infections. Kansas residents with backyard flocks and poultry operators face heightened exposure during this period.
USDA-confirmed detections cover one commercial and one backyard flock in Kansas, with 37,500 birds impacted in the past month. The source does not report whether further Kansas flocks have tested positive.
The players
U.S. Department of Agriculture (USDA)
The USDA is the federal agency that confirms animal disease detections and tracks poultry health across the country.
The details
Waterfowl migrating south during this season are carrying the virus and transmitting it to poultry flocks. The USDA has confirmed the infections in one commercial and one backyard flock in Kansas.
Timeline
Nearly 3 million U.S. birds were impacted in the last 30 days, as of November 12, 2026.
37,500 Kansas birds were impacted in the last month, as of November 12, 2026.
Waterfowl migration is underway in November 2026, raising transmission risk.
Seasonal Patterns
The Kansas detections follow the fall pattern in which migrating waterfowl transmit highly pathogenic avian influenza to domestic flocks. This seasonal risk is why poultry monitoring intensifies each autumn.
Backyard flock owners should watch birds for signs of illness and limit contact with wild waterfowl. Report unusual poultry deaths to state or federal animal health officials promptly.
The takeaway
Wild waterfowl are the primary carriers of avian influenza during migration, so keeping domestic birds separated from wild flocks is the most effective everyday precaution. Bird watchers who observe sick or dead wild birds should avoid handling them and report the sighting to wildlife authorities.
