Nevada Department of Agriculture is reporting West Nile Virus infections in two horses; one in Churchill County and one in Clark County. While horses are not a source of human infection, a horse with WNV is an indication that other horses and people are at risk.  NDA’s state veterinarian, Dr. JJ Goicoechea,says it’s important for horse owners to vaccinate their animals against West Nile Virus. The Animal Disease Lab identified West Nile positive mosquito pools in Clark, Churchill, Elko, Douglas, Lincoln and Washoe Counties. Mosquitos also tested positive for Saint Louis Encephalitis in Clark and White Pine Counties. Mosquito season is expected to end with the first frost in October. Till then all Nevada residents should take precautions such as eliminating mosquito-breeding sites, using insect repellents to fight the bite and keeping horses vaccinated against WNV and Western Equine Encephalitis.
