Three horses on two Hidalgo County, Texas, farms have developed vesicular stomatitis, adding to five other recent cases in the state. The horses have the same viral strain as the earlier cases in Kinney County, but there is no known connection between the Hidalgo County farms, and the affected horses haven't traveled recently. The virus, with symptoms that resemble those of foot-and-mouth disease, may be transmitted via fomites contaminated with saliva or fluid from ruptured lesions, but it is also transmitted by biting insects.
