The Texas Animal Health Commission (TAHC) has reported that vesicular stomatitis (VS) has been identified in three more horses in that state.

On May 28, the TAHC announced that VS had been confirmed in five Kinney County horses. The commission announced June 11 that three additional horses, all located in Hidalgo County, have tested positive for the disease. On June 5, two horses residing approximately 24 miles northwest of Edinburg were confirmed positive for VS, and a third horse residing three miles northwest of Edinburg was confirmed positive on June 9. These new cases are unrelated, the TAHC said.

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 these symptoms to their veterinarian immediately. Most animals recover well with supportive care by a veterinarian, but some lesions can be painful.

The newly identified infected premises are currently under TAHC quarantine. Affected horses will be monitored by regulatory veterinarians until all lesions have healed and a decision is made to release the quarantine (a minimum of 21 days). There is no known exposure to other horses around the state or at any equine events.

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.
