The Iowa Department of Agriculture and Land Stewardship has confirmed new cases of Highly Pathogenic Avian Influenza (H5N1) in backyard flocks in Van Buren and Keokuk counties, marking the state's third and fourth cases of the virus in 2026. While the risk to the general public remains low, state officials are advising poultry producers and backyard flock owners to take extra precautions to protect their birds.

Why it matters

Avian influenza outbreaks can be devastating for the poultry industry, leading to the culling of infected flocks and significant economic losses. The latest detections in Iowa highlight the ongoing threat posed by the H5N1 virus and the need for vigilance among producers to prevent the spread of the disease.

The details

The new cases were confirmed by the Iowa Department of Agriculture and Land Stewardship and the USDA Animal and Plant Health Inspection Service in backyard flocks in Van Buren and Keokuk counties. Symptoms of the virus in birds can include sudden death, decreased egg production, swelling, difficulty breathing, and lack of energy. While the virus can be carried by wild birds without them appearing sick, it is often fatal in domestic poultry.
