Agriculture officials discovered in late April that two horses in southern New Mexico were infected with vesicular stomatitis. 

Those horses, along with three others that lived on the same property in Otero County, were quarantined, and no other infections were found by mid-May, according to information from the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service.

The infected horses had clinical signs of the disease, and USDA testing confirmed the infections April 30, APHIS information states. Properties containing infected animals have to be quarantined until at least 21 days after lesions in the last affected animals have healed. Dr. Dave E. Fly, New Mexico’s state veterinarian, announced May 10 that all livestock leaving Otero County would need to be inspected by a veterinarian within seven days of transportation to a New Mexico livestock auction or public event or to another state.

Vesicular stomatitis is a viral disease that affects horses, swine, and cattle and other ruminants. Signs of infection in livestock include excessive salivation and blisterlike lesions. Cattle can develop teat lesions and mastitis; horses can develop vesicular lesions in and around their mouth and scabs on their muzzle, lips, and ventral aspect of their abdomen; and pigs can develop lameness from foot lesions.

Infected animals typically recover within two weeks, according to APHIS. Outbreaks typically occur in warm months in warm regions, often along waterways, agency information states.
