Vesicular Stomatitis (VSV) in Utah Update



As of November 30, 2015, There are No Active Cases of Vesicular Stomatitis in Utah

(Salt Lake City)  (News release posted November 1, 2015): State Veterinarian, Dr. Barry Pittman, is advising Utah livestock owners that the presence of vesicular stomatitis virus (VSV) continues in the following counties in Utah:  Duchesne, Uintah and Utah. Livestock owners should take appropriate measures to protect their animals. The affected premises are in various stages of quarantine. 

 Tests conducted by the USDA Plum Island Animal Disease Center, Foreign Animal Disease Diagnostic Laboratory in New York, confirmed the first case in early August. Since then other animals at different locations have tested positive for VSV.   

VSV is a livestock disease that rarely affects humans.  It primarily affects cattle and horses but can occasionally affect swine, sheep and goats.  VSV produces lesions in animal’s mouths and udders, but is not generally fatal.

Livestock owners are cautioned that 2015 has been an active season for vesicular stomatitis in the Southwest, and to be aware and alert.  Veterinarians caution livestock owners to not mingle their animals and take appropriate biosecurity measures.

     When a definite diagnosis is made on a farm, the following procedures are recommended:
• Separate animals with lesions from healthy animals, preferably by stabling. Animals on pastures tend to
be affected more frequently with this disease.
• As a precautionary measure, do not move animals from premises affected by vesicular stomatitis until
at least 14 days after lesions in the last affected animal have healed.
• Implement on-farm insect control programs that include the elimination or reduction of insect breed-
ing areas and the use of insecticide sprays or insecticide-treated eartags on animals.
• Use personal protective measures when handling affected animals to avoid human exposure to this

Owners intending to travel out of state with their animals are advised to check with the destination state animal health authorities before entering another state.
The Utah Department of Agriculture and Food (UDAF) Veterinarian’s Office asks livestock owners to report any symptoms to your local veterinarian, or the UDAF at: (801) 538-7109, (801) 538- 7161, This email address is being protected from spambots. You need JavaScript enabled to view it./

Many states have applied interstate movement restrictions of various types to livestock from states where this disease has been diagnosed.  Care should be taken to comply with regulations in the state of destination regarding interstate movement of livestock from Utah.

It is essential that veterinarians and livestock owners be on the alert for animals displaying clinical signs characteristic of the disease such as lesions in the mouth and on the dental pad, tongue, lips, nostrils, hooves, and teats. These blisters leave raw tissue that is so painful that infected animals generally refuse to eat or drink and may show signs of lameness. Severe weight loss usually follows, and in dairy cows, a severe drop in milk production commonly occurs.

While vesicular stomatitis can cause economic losses to livestock producers, it is a particularly significant disease because its outward signs are similar to those of foot-and-mouth disease, a foreign animal disease of cloven-hoofed animals that was eradicated from the United States in 1929.

There is no specific treatment or cure for vesicular stomatitis in livestock. Livestock owners can protect their animals by avoiding congregation of animals in the vicinity where vesicular stomatitis has occurred.
