Highly pathogenic avian influenza (HPAI) is a contagious viral disease that continues to impact domestic and wild birds. In March of 2024, HPAI was detected in dairy cattle in Texas, and has since spread rapidly across the United States. To date, it has not been detected in Canada in cattle.
In this new miniseries, Dr. Murray Gillies, a veterinarian and the Interim Division Director for the Canadian Animal Health Surveillance System, and Dr. Henry Ceelen, a bovine veterinarian and Secretary Treasurer for the Canadian Association of Bovine Veterinarians, join Dr. Steven Roche of ACER Consulting to discuss HPAI in dairy cattle, including disease presentation, spread, and prevention, as well as the Canadian response.
