Wyoming See First Fatal Horse Virus Case

Wyoming has recorded its first case of a potentially fatal horse virus this year. 

State veterinarian Jim Logan said Wednesday that tests confirmed a case of equine herpes virus-1 in a horse from Johnson County. 

The horse has been isolated from others and the location is under quarantine.

Another horse from the same location has been euthanized due to symptoms, but tests to confirm the virus are pending.

Logan says the Wyoming case is not related to the Ogden, Utah cutting horse event, where the latest virus outbreak began in may and has spread across the west and Canada.

At least a dozen horses have been euthanized.
