USDA reports confirmed U.S. cases of vesicular stomatitis virus in 2026. The contagious disease mainly affects horses and cattle, can cause painful blister-like lesions and drooling, is associated with biting insects, and can occasionally infect people.
Three quick summaries of the same article, tailored for different readers.
Vesicular stomatitis often causes painful blisters around the mouth, nose, udder, sheath, ears, or coronary band. Do not move an affected animal or invite visitors before veterinary guidance. Separate sick animals when it can be done safely, reduce insect exposure, and use hygiene precautions because people can occasionally become infected.
USDA provides current reports, signs, and reporting instructions.Intake should capture species, premises, animal movement, insect exposure, lesion distribution, fever, herd mates, and human illness. Avoid routine traffic through a suspect area. Vesicular stomatitis can resemble higher-consequence foreign animal diseases, so sample collection and communication may be directed by animal-health officials.
The USDA page includes situation reports and instructions for veterinarians.The virus primarily affects horses and cattle, with lesions developing after a short incubation period. The importance of the case extends beyond supportive care: similar lesions can occur with foot-and-mouth disease and other vesicular syndromes. Diagnostic approach therefore includes biosecurity, epidemiologic history, official notification, and laboratory exclusion—not simply pattern recognition.
