Avian Influenza (affects only poultry)
Avian Influenza (AI) is a disease caused by an influenza type A virus. It can infect both poultry and wild birds. AI is classified by the combination of proteins they display, and further classified by the virus’s ability to produce disease in domestic birds. Low pathogenicity (LPAI) strains occur naturally in wild bird populations, which show no signs of the disease. LPAI also creates little or no signs of illness in domestic poultry.1 Highly pathogenic AI (HPAI) strains are very infectious, and often fatal to domestic poultry, but wild birds may not show signs of disease. HPAI also spreads rapidly from flock-to-flock.
