As of Wednesday, the Colorado Department of Agriculture’s State Veterinarian’s Office has 189 locations under quarantine after horses and cows tested positive for Vesicular Stomatitis (VS); 88 of the 277 quarantines have now been released. Fortunately, the disease has not made its way to Northwest Colorado. VS can be painful for animals and costly to their owners. The virus typically causes oral blisters and sores that can be painful causing difficulty in eating and drinking. Positive premises are eligible for quarantine release 21 days after lesions have healed in all affected animals. If you plan to transport your horse to another state, be sure to check with the State Veterinarian’s Office in the state of destination as to any special new restrictions for movement of your horse into their state. Some states have instituted new requirements for the import of Colorado horses due to the VS outbreak.
