The Iowa Department of Agriculture and Land Stewardship and the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service have detected a case of highly pathogenic avian influenza in a commercial layer flock in Sioux County, Iowa.
This is Iowa’s sixth detection of H5N1 HPAI within poultry in 2024.
H5N1 HPAI is a viral disease that affects both wild and domestic bird populations. H5N1 HPAI can travel in wild birds without those birds appearing sick, but is often fatal to domestic bird populations, including chickens and turkeys. H5N1 HPAI can also impact dairy cattle, and 13 cases were detected in Iowa dairy herds in June 2024.
With supportive care, dairy herds recover with limited or no mortality associated with the disease.
