Mosquito Surveillance Reports
The Southern Nevada Health District’s Vector Surveillance Program regularly submits mosquito pools to the Nevada Department of Agriculture to test for West Nile virus, St. Louis Encephalitis, and Western Equine Encephalitis. West Nile virus-positive mosquitoes have been identified in Clark County every year since 2004, with the exception of 2010. In 2016, the Health District has identified an increase in St. Louis Encephalitis-positive mosquitoes throughout Clark County. Western Equine Encephalitis is occasionally identified in Clark County.
The Vector Surveillance Program conducts ongoing surveillance for the Aedes albopictus or Aedes aegypti mosquitoes known to carry Zika virus as well as chikungunya, and dengue. The Health District detected Aedes aegypti mosquitoes in Southern Nevada in 2017.
Residents can report green swimming pools and standing or stagnant water sources to local code enforcement agencies. Contact information for local jurisdictions’ code enforcement is available on the Health District website.
