At the writing of this article, cases of Vesicular Stomatitis (VS) have been found in Texas, New Mexico, Colorado, Wyoming and Oklahoma. The last VS outbreak occurred in 2015. The outbreak involved eight states, and there were 823 infected premises. The reason for this article is to alert the public about the disease and the restrictions placed on incoming livestock from those four states.
Vesicular stomatitis is a viral disease that affects primarily horses and cattle. Pigs, sheep, goats, llamas and alpacas also can be infected, and on rare occasions humans can be infected. The disease normally occurs in the western and southwestern United States during the warmer months of the year and tends to be seen along waterways. Transmission occurs by direct contact with infected animals or by blood feeding insects.
