The Washington State Department of Agriculture (WSDA) reported Feb. 6 that a King County facility has been quarantined after a horse tested positive for equine herpesvirus-1 (EHV-1).

In an Ag Brief on the department’s website, State Veterinarian Brian Joseph, DVM, said this case is unrelated to another recent EHV case in King County.

“This is a different strain of EHV-1 than the virus strain that lead to an earlier quarantine at a separate horse facility in Woodinville this past December,” his statement said. “The most recent case involves a non-neuropathogenic strain of equine herpesvirus, though it is still serious and can cause respiratory problems in horses.
