Avian Influenza Transmission

Routes of Transmission

How do birds get avian influenza?

  • Avian influenza is transmitted, or spread, in many different ways.1,6

  • Infected birds spread the influenza virus in their saliva (spit), nasal secretions (snot), and feces (poop).

  • Birds become infected with avian influenza through contact with infected birds, or through contact with contaminated materials such as soil, cages, feed and water.

  • Rodents and insects may also carry the virus on their body.

  • Vehicles and equipment can transport the virus to your backyard and birds as well.
