As of this week, the Colorado Department of Agriculture’s State Veterinarian’s Office has 42 locations in 14 counties under quarantine after horses, mules, and cattle herds tested positive for Vesicular Stomatitis (VS). That includes a location in Moffat County. The Northwest part of the state has largely avoided outbreaks of the disease until recently. A couple of months ago, there were two cases in Rio Blanco County, and one in Routt County. Those locations have since been released from quarantine. The state’s latest report, however, says there is now a location in Moffat County that has been quarantined. The exact location is not revealed. Livestock owners who suspect an animal may have VS or any other vesicular disease should immediately contact their local veterinarian. Livestock with clinical signs of VS are isolated until they are 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.
