The Utah state veterinarian’s office has now confirmed seven equine herpesvirus-1 (EHV-1) cases, according to a March 6 statement.

"The state veterinarian’s office is restricting the movement of the animals at eight locations in Cache County as a precaution to prevent the spread of the disease," the statement read. "The outbreak remains confined to Cache County, as there have been no other reports of EHV-1 symptoms in horses in other areas of the state. Nonetheless, horse owners throughout Utah are advised to take extra biosecurity precautions when taking their animals to shows or public arenas."

The outbreak began Feb. 26 when two horses tested positive for the disease; two additional horses were confirmed to be EHV-1 positive the following day. On March 4, officials announced that two more horses had tested positive for the disease. Two of the eight EHV-1 positive horses have been euthanized as a result of the disease; the remaining animals are being treated and are under veterinary care, the statement read
