The Colorado Department of Agriculture reports that 65 locations in 15 counties are under quarantine for horses, mules or cattle herds testing positive for Vesicular Stomatitis.
The viral disease causes a fever after infection and leads to ulcers or blisters around the mouth of an animal.
“This outbreak is not contained to one specific area of the state. The overall number of cases in 2015 is lower than 2014 and we are seeing a more diffuse occurrence across the state,” says state veterinarian Keith Roehr.
Currently, there are no USDA approved vaccines for Vesicular Stomatitis.
If a livestock owner should have an animal suspected of Vesicular Stomatitis they need to immediately contact their local veterinarian and isolate the animal to prevent the spread.
“While we cannot disclose the exact location of the infected livestock, it is not very contagious from animal to animal. The primary method of spread is through insect vectors, primarily biting flies. The key to remember is to take steps to reduce the fly populations near livestock,” says Roehr.
