Cache County, Utah, is no longer under a quarantine in effect since February for equine herpesvirus after the final two horses with suspected exposure to the virus underwent a 28-day watch period and did not develop symptoms, according to the Utah State Veterinarian's Office. Four of nine confirmed cases of EHV-1 resulted in euthanasia due the severity of symptoms. The outbreak was traced to a contaminated tie-down rail at the Cache County Fairgrounds Horse Arena. Utah State Veterinarian Bruce King reminds horse owners that EHV-1 is still present in the area, and proper precautions should always be followed.
