On June 17, the National Veterinary Services Laboratories (NVSL) in Ames, Iowa, confirmed the finding of vesicular stomatitis (VS) in a horse on a premises in Garfield County, Utah. This is the first confirmed case of vesicular stomatitis in the State of Utah in 2005.


Utah had no cases of vesicular stomatitis in 2004.


The owner took the two affected horses on a pleasure ride on May 22 in the southeastern part of the state along the Escalante river. The owner noticed an abundance of biting flies and insects on that ride and first noticed the animals were sick on May 31.


A subsequent case of vesicular stomatitis also was diagnosed by NVSL on June 17 in a horse on a premises in Davis County, Utah. Vesicular stomatitis has not been seen in this part of the State in past outbreaks
