What is Avian Influenza?
Avian Influenza, commonly known as AI or the "bird flu," is an infectious disease found in birds caused by type A strains of the influenza virus. Since January 14, 2022, there have been several US-based cases of highly-pathogenic Avian Influenza detected in wild waterfowl, commercial and backyard poultry and non-poultry flocks across the country. Members of the poultry industry are concerned about the continued potential for new outbreaks during fall and spring wild bird migrations.
The USDA-APHIS department is diligent about the research, prevention, and containment of AI in partnership with those who raise poultry. Being vigilant with strict bio-security is your best defense. Please do your part.
Birds infected with the disease sometimes show symptoms and some die within 48 hours.
- Lethargy (lack of energy)
- Decreased appetite
- Coughing, Sneezing
- Nasal drainage
- Sudden death (without symptom)
- Discolored combs, wattles, and legs (hemorrhaging/purple/black)
- Swollen eyelids, wattles, hocks, comb, or head.
Symptoms (LPAI - Low Pathogenic)
Most cases show no signs of infection or even minor symptoms. If you suspected your birds are infected, call your local cooperative extension office, your veterinarian, state veterinarian, or state animal/poultry diagnostic laboratory. Or call USDA toll-free at 1-866-536-7593 and they will put you in touch with a local contact who can help you.
