Vesicular Stomatitis Virus (VSV)

Vesicular Stomatitis (VSV) is a viral disease that primarily affects cattle, horses, and swine and occasionally sheep, goats, llamas, and alpacas. Humans can also become infected with the disease when handling affected animals, but this is a rare event.

Important points to remember for veterinarians: 

VSV is a reportable disease, please call our office at (303) 869-9130 or USDA APHIS Veterinary Services – Colorado office (website) as soon as possible to report suspicion of disease.
Place a HOLD ORDER on the premises as soon as VS is suspected, in order to restrict the movement of affected and exposed animals.
3. TEST - Collect BOTH Swab AND Serum
When sampling horses for vesicular stomatitis, please obtain a swab of the affected area AND draw blood to obtain serum for a CF test.
