Two horses in Cache County, Utah, tested positive for EHV-1, and three others are believed to be infected. The two horses with confirmed cases were euthanized while the other three are under quarantine. Most of the horses had been at the Cache County Fairgrounds, so that facility's riding arena has been closed. Utah State Veterinarian Bruce King is urging horse owners to watch for symptoms of the illness in their horses, report any health problems to their veterinarian and quarantine horses returning from shows or other events.
