Reno, 08/10/2011 – The Nevada Department of Agriculture’s Animal Disease and Food Safety Laboratory has to date identified positive mosquito (Culex tarsalis) pools from Lyon County, Churchill County and Clark County. Additionally a clinically sick horse from Lyon County was confirmed positive for WNV infection.
The state wide mosquito surveillance program is based on the work of vector control agencies in Washoe, Clark, Churchill and Douglas County as well as Mason Valley, Lyon County. Surveillance in rural counties is conducted through the State Entomologist’s office at the Nevada Department of Agriculture. All samples are submitted to the Animal Disease and Food Safety Laboratory at NDOA for testing for three endemic arbo-viral diseases, West Nile Virus, Saint Louis Encephalitis Virus and Western Equine Encephalitis Virus, all of which can cause severe disease and death in humans.
“West Nile Virus season is upon us and the viruses are here to stay.’ Said Dr. Phil LaRussa, Nevada’s State Veterinarian: ‘It is very important to keep WNV and WEE vaccinations in horses current to prevent the clinical disease and death in horses. A variety of vaccines with proven efficacy are available and all horses, including brood mares can be safely protected through the routine use of available vaccines.’
