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.
The TAHC advises poultry owners to practice strong biosecurity and remain vigilant in examining the health of their birds. If your birds exhibit unusual death loss or signs of illness, or you observe large scale sickness and mortality of wild birds, call your private veterinarian or the TAHC immediately at 1-800-550-8242.
