PULLMAN, Wash. — The Washington State University College of Veterinary Medicine has confirmed two more horses with Equine Herpes Virus or EHV-1.

Confirmation came late yesterday for one and at 10:15 a.m. today for the second. Both horses are inpatients in the Veterinary Teaching Hospital.

The EHV-1 type is confirmed as the neurotropic form based upon clinical neurologic signs shown by one of the horses both of which are now in isolation.

The total number of horses confirmed to have EHV-1 in Washington state now stands at six, according to the Washington State Department of Agriculture.

The discovery of two more infected horses at WSU means the restrictions for new, non-emergency horse or camelid patients coming to WSU’s Veterinary Teaching Hospital will be in place for a minimum of 21 more days. 

Emergency services are still available but owners must call ahead first to ensure the hospital can make special accommodations to protect any incoming animals.  The phone number is: 509-335-7073.
