Vesicular Stomatitis

Texas Animal Health Commission (TAHC)

With confirmed cases of Vesicular Stomatitis this year in Texas, all horses owners need to be aware and educate themselves on the disease.
Vesicular stomatitis is a viral disease that primarily affects horses and cattle. VS also can affect sheep, goats, llamas, alpacas, swine, deer and some other species, including bobcats, raccoons and monkeys. Humans can also become infected with the disease when handling affected animals, but this is a rare event. Vesicular stomatitis has been confirmed only in the Western Hemisphere. It is known to be an endemic disease in the warmer regions of North, Central, and South America, but outbreaks of the disease in other temperate geographic parts of the hemisphere occur sporadically
In the past decade, the Southwestern and Western United States have experienced a number of vesicular stomatitis outbreaks. Outbreaks usually occur during the warmer months, often along waterways. In some years, only a few premises in a single state have been affected. However, in other
years, multiple states and many premises have been involved. Since there could be a vesicular stomatitis outbreak in any given year, it is essential that veterinarians and livestock owners be on the alert for animals displaying clinical signs of the disease. At first glance, blisters, erosions
in the mouth, excessive salivation, or crusty sores around an animal’s muzzle, teats or hooves bring to mind the dreaded and highly contagious foreign animal virus, Foot-and-Mouth Disease (FMD). To read more puck up the September 2015 issue of NTFR or visit
