Avian Influenza
What is avian influenza?
Avian influenza (AI) is a disease caused by a virus that primarily infects domestic poultry and wild birds such as geese, ducks, and shore birds. Each year, there is a "bird flu" season, and some forms of the "bird flu" are worse than others. Wild birds, especially waterfowl, are a natural reservoir for mild strains of AI. Highly pathogenic avian influenza (HPAI) H5N1 is a strain known to kill both wild birds and commercial poultry.
In March 2022, the HPAI H5N1 virus was detected in Ontario in wild and commercial poultry. This same strain of the virus has also been found in many other jurisdictions across the world, including other Canadian provinces and American states. The spread has been primarily attributed to the migration of infected waterfowl.
The HPAI H5N1 virus does not easily cross from birds to humans, and the current strain has been listed as lower than normal concern for spread to people.
There have been no human cases of avian influenza in Durham Region.
Durham Region residents should:
