What Is Vesicular Stomatitis In Horses?
Vesicular stomatitis or VS is a viral disease that affects horses. In addition, it can also affect cattle, pigs, sheep, goats, llamas, and alpacas. In rare cases, humans can also become infected with vesicular stomatitis when handling affected animals.
Vesicular stomatitis is only confirmed in the Western Hemisphere. It is an endemic disease that affects the warmer regions of North, Central, and South America. Outbreaks may also occur in other temperate geographic parts of the hemisphere on occasion.
States within Southwestern and Western America have experienced a number of vesicular stomatitis outbreaks. In 2015, the most recent and largest vesicular stomatitis outbreak occurred. Outbreaks generally happen during the warmer months. It is most common for outbreaks to occur along waterways. Due to the risks that come with it and how quickly it can spread, vesicular stomatitis is a state-reportable disease.
How Is Vesicular Stomatitis Transmitted?
It is believed that insects including biting flies and midges contribute to maintaining the virus. Black flies, sand flies, and midges are also known to transmit it. However, many researchers also believe that there are other insect vectors to spread the disease that has not yet been identified.
In addition to insects, vesicular stomatitis also can be transmitted from horse to horse through saliva or fluid from ruptured blisters. In addition, physical contact among horses along with contact with shared items such as buckets, equipment, housing, trailers, feed, and bedding by an infected horse can also spread it.
The time from exposure od the virus to the onset of clinical signs is two to eight days. Horses must generally isolate for 21 days from other horses after being diagnosed.
Symptoms Of Vesicular Stomatitis In Horses
Horses with vesicular stomatitis will often develop blister-like lesions on the tongue, mouth lining, nose, or lips. Horses will also generally have excessive drooling, a fever, trouble eating, lameness, and have inflammation and erosions at the coronary band of the hoof. In the Southwestern United States, crusting lesions of the muzzle, lower abdomen, penis, and udder are also typical symptoms as well.

Intravenous fluids may be given if a horse becomes dehydrated from not drinking enough water. Another concern with vesicular stomatitis is a secondary bacterial infection of ulcerated areas is another concern. Antibiotics can be given in the case of fever, swelling, inflammation, or pus developing around the sores.
Using dilute antiseptic solutions, such as chlorhexidine in water, can help reduce the chance of secondary bacterial contamination. Besides that, pretty much the only thing to do is wait for the disease to run its course.
If a horse is diagnosed with vesicular stomatitis, it should be quarantined for two weeks. In addition, other horses on the property that could have been possibly exposed should not leave the property for two weeks.
