PULLMAN, Wash. (AP) -- Veterinarians at Washington State University have confirmed the state's ninth case of equine herpes virus.
The privately-owned horse was admitted to the university's College of Veterinary Medicine for acute colic, an intestinal illness. The horse was admitted under quarantine because it was considered high risk for equine herpes virus.
Positive test results on Tuesday evening confirmed the virus.
This marks the sixth case confirmed at WSU and ninth case overall in the state. No horses have died from the virus in Washington.
