The state now has confirmed an animal disease at 65 locations in 15 counties, up from 11 last week, and the Colorado Department of Agriculture's state veterinarian has issued a quarantine order for those areas.
Vesicular Stomatitis turned up in Boulder, Ouray, Pueblo and Rio Grande counties in the past week. Most of the cases are in Larimer, Mesa and Delta counties. The 65 cases so far this year are lower than last year, but the state veterinarian says livestock owners should be on the lookout for signs of the disease with the State Fair now underway in Pueblo.
Human cases of VS are rare, but when they do show up it's usually among those who handle infected animals. VS in humans can cause flu-like symptoms and sometimes lesions or blisters.
