Disease Advisory from OMAFRA on canine influenza in Ontario

“Since January 2018, three clusters of dogs infected with H3N2 canine influenza virus (CIV) have been identified in Essex County (2) and in the Simcoe-Muskoka area. These are the first known incursions of H3N2 canine influenza in Canada. The virus is widespread in some parts of Asia and is causing outbreaks inthe United States, especially in animal shelters. Canine influenza virus is of concern because it is highly transmissible between dogs, particularly in areas,such as Canada, where dogs do not have natural immunity from previous infection and where canine influenza vaccination is rare.”
