On Apr. 15, 2022, The Idaho State Department of Agriculture (ISDA) announed it had received confirmation of multiple cases of Highly Pathogenic Avian Influenza (HPAI) virus in two separate flocks of domestic chickens in Gooding County and Caribou County. The affected flocks appear to be unrelated.

HPAI is a viral disease and requires rapid response because it is highly contagious and often fatal to chickens. ISDA will work with the U.S. Department of Agriculture to respond to cases. It is uncommon for humans to become infected with avian influenzas, but symptoms may include conjunctivitis, fever, lethargy, aches, coughing, or diarrhea. Being in direct contact with domestic birds is the highest risk activity.

HPAI is carried by waterfowl (geese and ducks) along their migratory path. Idaho is within the Pacific Flyway. Domestic birds and poultry are very susceptible to morbidity and mortality once infected. HPAI is transmitted between birds through close contact (mucous), fecal matter, and sometimes as an aerosol. It is often carried on objects such as tools, vehicles, clothes, and boots, which can transfer the virus from one location to another.
