As of November 20, 2024, Highly pathogenic avian influenza – HPAI (H5N1) has been detected in 552 dairy cattle herds in 16 states in the US. See USDA map.
There have been no cases detected to date in Canadian dairy cattle.
Animal Health Canada with its divisions have been working closely with government, industry, veterinary associations, regional/national surveillance partners, and laboratorians on the situation.
As this is an evolving issue, we will continue to work with our members and share the most up-to-date information as we receive them on this page.
Please refer to our resources list at the bottom of the page for the most updated resources.

Mental Health supports for veterinarians
This may be a time of increased stress and anxiety for veterinarians as they discuss and prepare for HPAI with their clients.
The Canadian Veterinary Medical Association's incoming Director of Wellness, Dr. Kathy Keil, has offered the following resources for those who feel that they may be beneficial to them:
The CVMA website outlines supports available to Canadian veterinarians:
https://www.canadianveterinarians.net/veterinary-resources/veterinary-health-and-wellness-resources/mental-health-awareness-resources/who-ya-gonna-call/
CVMA also offers an anonymous and confidential peer-to-peer online community for all Canadian veterinarians and student veterinarians through Togetherall. ABVTA now offers this online service for AB RVTs too. This community is an opportunity for veterinarians to reach out to their peers to share a situation or an issue where they need a peer to listen, offer support and guidance. The community has 24/7/365 oversight with a licensed mental health professional for additional safety.
