In a follow-up to a report earlier this week, The Colorado Department of Agriculture’s State Veterinarian’s Office has placed seven locations under quarantine after horses tested positive for Vesicular Stomatitis (VS). The quarantines are located in Weld and Boulder counties; results on additional tests in other counties are pending.
Veterinarians and livestock owners who suspect an animal may have VS or any other vesicular disease (clinical signs of the disease include vesicles, erosions and sloughing of the skin on the muzzle, tongue, teats and above the hooves of susceptible livestock) should immediately contact State or federal animal health authorities.
Livestock with clinical signs of VS are isolated until they are healed and determined to be of no further threat for disease spread. There are no USDA approved vaccines for VS.
While rare, human cases of VS can occur, usually among those who handle infected animals. VS in humans can cause flu-like symptoms and only rarely includes lesions or blisters. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
