2022 Highly Pathogenic Avian Influenza
2022 HPAI Background
- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed several findings of the presence of highly pathogenic avian influenza (HPAI) in wild waterfowl in the Atlantic flyways in January 2022. On February 8, 2022 APHIS confirmed H5N1 HPAI in a commercial turkey flock in Dubois County, Indiana. Since then it has been confirmed in multiple states and flock types.
- The first case of H5N1 in Texas was confirmed on April 2, 2022.
- According to the CDC, Recent Bird Flu Infections in U.S. Wild Birds and Poultry Pose a Low Risk to the Public.
- Federal and State partners are working jointly on additional surveillance and testing in the nearby area, following existing avian influenza response plans.
- The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in poultry operations, live bird markets, and in migratory wild bird populations.
- Commercial poultry producers and backyard flock owners should continue to practice strict biosecurity; most importantly, prevent birds from exposure to wild waterfowl.
Avian Influenza (AI) is a flu virus that may cause illness in domestic poultry, fowl and birds. Migratory waterfowl are a natural reservoir for this disease.
There are many strains of the AI virus. Based on the severity of illness caused by the virus, these strains are put into two classifications, low pathogenic (LPAI) and highly pathogenic (HPAI). LPAI causes only minor illness and occurs naturally in migratory waterfowl. HPAI spreads rapidly and has a high death rate in birds.

What can bird owners do to protect their flocks? By practicing biosecurity, you can help reduce the chances of your birds being exposed to animal diseases such as AI.
- Eliminate opportunities for your birds to interact with wild birds. We know that wild waterfowl are carriers of disease. The best way to avoid diseases that wildlife carry is to keep domestic animals separated from the wild.
- If you have birds at home, do not visit another farm, home or facility that also has birds. If you must visit another premises, be sure to shower and put on clean clothes and shoes beforehand.
- Remember that vehicles can be vehicles for disease transmission. Before you drive down the road, consider where you are going. Will you be heading to the fair, another farm or a live bird market? If the answer is yes, be sure your vehicle is clean and free of dirt, manure and other organic material.
- Early detection can help prevent the spread of disease. Knowing the signs to look for and monitoring the health of your birds on a regular basis is very important. Some signs to look for include nasal discharge, unusually quiet birds, decreased food and water consumption, drop in egg production, and increased/unusual death loss in your flock.
- Report sick and dead birds immediately. If your birds appear sick or you have experienced increased mortality, immediately call your private veterinarian or your TAHC region office.
