PULLMAN, Wash.—A privately owned horse admitted to Washington State University’s College of Veterinary Medicine teaching hospital for an unrelated, emergency intestinal illness has also been confirmed positive for Equine Herpes Virus or EHV-1.  

The horse was admitted under the WSU Infection Control Protocol instituted on re-opening of the hospital.  On arrival the animal was determined to be a “High Risk” suspect EHV-1 case.  The horse was admitted under strict isolation protocol guidelines and was tested for EHV-1.  Positive nasal swab results received yesterday evening confirmed the veterinarians’ suspicions.

The Veterinary Teaching Hospital equine section remains open and available to any clients needing care for their animals.

The new case represents Washington’s ninth positive case and the sixth that has been confirmed at WSU. It was reported to the Washington State Department of Agriculture this afternoon.  No equine deaths have occurred due to EHV-1 in Washington.

Known as colic, the horse’s intestinal complaint resolved medically and did not require surgery.  The animal could return back to its owner’s property under strict isolation if it remains stable.

Horse, alpaca, and llama owners seeking care for their animals are encouraged to call WSU first to ensure the hospital can continue to protect any incoming animals needing care.  The phone number is: 509-335-0711.
