AQHA is aware of the Equine Herpesvirus Type 1 (EHV-1) outbreak that is being linked to an equine event in Waco, Texas. We are in communication with both the Oklahoma Department of Agriculture and the Texas Department of Agriculture regarding the potential spread in both states and, possibly, beyond.
AQHA always recommends following good biosecurity practices when traveling with your horses. Best practices for preventing EHV transmission include minimizing horse-to-horse contact and exposure to aerosolized nasal discharge or contaminated surfaces including clothing, people, buckets and barn items, as well as disinfecting surfaces and equipment that may have come into contact with infected horses.
Owners should monitor their horses, avoid unnecessary travel and contact their veterinarians with concerns.
We will continue to communicate with both states, monitor the situation and provide updates to our AQHA members as they become available.
Texas Department of Agriculture Commissioner Sid Miller released this press release with more information today. The Oklahoma Department of Agriculture’s website also contains resources and alerts.
You can visit the Equine Disease Communication Center website for more information about biosecurity practices, monitoring, quarantining and more.
