Currently, there is no vaccine for Vesicular Stomatitis. Vesicular Stomatitis (VS) can appear in horses as fever, followed by blister-like and swollen lesions in the mouth, tongue, lips and nose.1,2 VS is thought to be spread through horse-to-horse contact of open sores and salvia, or transmitted by biting insects such as flies and gnats.2 An accurate diagnosis should be attained through blood tests or swab samples to rule out an alternative cause for the lesions.1 If infected, horses should be isolated and treated with an anti-inflammatory to reduce swelling.2,3 Antibiotics can be given if sores develop secondary bacterial infection, but there are few options other than waiting for the healing process to occur.3 

Prevent further contamination by cleaning and disinfecting stables, bunks, trailers and other regularly used equipment.3
