Several new cases of vesicular stomatitis (VS) have been confirmed in horses in Texas and Colorado over the past week. The Colorado Department of Agriculture also reported diagnoses of VS in two cattle earlier this month, and several states have modified their livestock import requirements to prevent spread of the disease.
Since the last USDA situation report on August 6, 64 new premises have been confirmed for VS infections in Colorado, 62 due to infections in equines and two with infections in cattle. In Texas, the latest report showed 11 new premises with infected equines and one with infected cattle.
