Notifiable Avian Influenza

Avian influenza (AI) is a contagious viral infection that can affect several species of food producing birds as well as pet birds and wild birds. AI viruses can be classified into two categories: low pathogenicity (LPAI) and highly pathogenic (HPAI) forms, based on the severity of the illness caused in birds.

Avian influenza viruses, such as the highly pathogenic H5N1 virus present in Asia, may, on rare occasions, cause disease in humans. Transmission to humans has occurred through close contact with infected birds or heavily contaminated environments.

In Canada, highly pathogenic avian influenza and low pathogenicity H5 and H7 avian influenza viruses are considered to be Notifiable Avian Influenza, which is a reportable disease under the Health of Animals Act. All cases must be reported to the Canadian Food Inspection Agency (CFIA).
