EHV-1 Positive Horse in King County, Washington

A non-neurologic EHV-1 case was confirmed in Washington state.

The Washington State Department of Agriculture (WSDA) reports a confirmed case of non-neuropathogenic equine herpesvirus type 1 (EVH-1). The confirmation was by a nasal swab (PCR) from a horse in King County that was recently transported from Portland Meadows Racetrack in Oregon. 

The horse is not demonstrating clinical signs of illness at this time. 

WSDA has placed the facility under quarantine and is actively monitoring other horses at the facility that have been exposed to the infected index horse.

The Equine Disease Communication Center (EDCC) works to protect horses and the horse industry from the threat of infectious diseases in North America. The communication system is designed to seek and report real time information about disease outbreaks similar to how the Centers for Disease Control and Prevention (CDC) alerts the human population about diseases in people.
