CHEYENNE – Vesicular Stomatitis Indiana serotype has recently been found in horses in Texas, New Mexico and most recently, Colorado.
Because of this, Wyoming State Veterinarian Jim Logan has implemented a 72-hour health certificate requirement on susceptible livestock being imported from any county where VSV has been diagnosed in the previous 30 days. This requirement is effective immediately.
Additionally, livestock originating from a state or area where VSV has been diagnosed must have the following statement recorded on the Certificate of Veterinary Inspection by the issuing accredited veterinarian.
VSV can affect equine species, cattle, swine, sheep and goats. The main symptoms are slobbering, blisters, and sores and sloughing of skin in the mouth, on the tongue, lips, and muzzle, inside the ears, on the coronary band above the hooves and the sheath and udder. Anorexia is a common symptom, and lameness and weight loss may also occur.
Flies and midges are the main vectors for VSV. The virus is also spread through direct contact with infected livestock, and indirectly through contact with contaminated equipment and tack.
Livestock owners that suspect VSV in their animals should contact a veterinarian immediately. Vesicular Stomatitis is a reportable disease that should be immediately reported to the Wyoming state veterinarian at 307-857-4140 or to the USDA APHIS Veterinary Services’ Wyoming Office at 307-432-7960.
