Avian influenza virus is excreted from the respiratory and digestive tracts of infected birds and is transmitted directly through bird-to-bird contact or indirectly by aerosol droplets or exposure to virus-contaminated inanimate objects or substances known as fomites. The virus can also be transported to other premises by people through contaminated shoes, clothing, equipment, and vehicles. Please visit the Avian Influenza Homepage for additional resources and information.
