Texas authorities confirm there is a new case of vesicular stomatitis (VS) in a horse. This is the state’s 13th case since the end of May.
The Texas Animal Health Commission (TAHC) states the infected horse is the second in Nueces County in South Texas. The newly infected premises is quarantined for 21 days after all lesions have healed.
Seven locations in four Texas counties have been confirmed with vesicular stomatitis. All horses have tested positive for the New Jersey serotype.
On May 28, the agency announced the first cases of vesicular stomatitis in the U.S. for 2014. The disease was last seen in Texas in 2009.
The first five horses with the infection were on a pasture in a group of rescue horses located in Kinney County, according to officials. Cases have also been confirmed in San Patricio County and Hidalgo County.
Most animals recover after a couple of weeks, but if the vesicles become infected, officials say the recovery process, which includes treatment of the horse’s symptoms, may take longer. Symptoms include blisters and sores in the mouth, tongue, muzzle, teats, sheath, or hooves.
While rare, humans can also be infected with the disease when handling affected animals. Symptoms are flu-like, with fever, muscle-aches and headaches.
Insects are thought to play an important role in the transmission of the virus, including sand and black flies.
Several states including Florida, Kentucky, Illinois, North Carolina, and Oklahoma have enhanced the entry requirements for Texas livestock, including horses, due to the cases of vesicular stomatitis.
