Officials confirmed vesicular stomatitis (VS) in another Texas horse late last week, according to a statement from the Texas Animal Health Commission (TAHC).

The newly confirmed case is in a horse residing in Nueces County, about 10 miles south of Mathis.

To date, VS has been confirmed in horses residing on six premises in four Texas counties. The current VS situation began on May 28, when the TAHC announced confirmation of VS in five horses in Kinney County. Shortly thereafter, three horses in Hidalgo County tested positive for VS . And on June 17, officials reported that three additional horses in San Patricio County were diagnosed with VS. All affected horses tested positive for the New Jersey serotype.

The newly identified infected premises is currently under TAHC quarantine and affected horses will be monitored by regulatory veterinarians while under quarantine. Premises are eligible for quarantine release 21 days after all lesions have healed. There is no known exposure to other horses around the state, or at any equine events.

The viral disease can cause blisters and sores in the mouth and on the tongue, muzzle, teats, or hooves of horses, cattle, swine, sheep, goats, llamas, and a number of other animals. Lesions usually will heal in two or three weeks. Because of the contagious nature of VS and its resemblance to other diseases such as foot and mouth disease, animal health officials urge livestock owners and caretakers to report clinical signs to their veterinarian immediately. Most animals recover well with supportive, but some lesions can be painful.

Several states have provided the TAHC with information on enhanced entry requirements they are imposing on Texas livestock (including horses) due to the VS cases in Texas. For information about these movement restrictions, contact the state or country of destination and/or visit www.tahc.texas.gov/news/2014-06-05_StateRestrictionsOnTX_VS.pdf.
