The Southern Nevada Health District’s Vector Surveillance Program says it's identified the first West Nile virus-positive mosquitoes of the season. 

One West Nile virus submission pool totaling three mosquitos was identified in the 89032 ZIP code. Additionally, a horse in the 89021 ZIP code has tested positive for West Nile virus as well.

“The identification of West Nile-positive mosquitoes is another reminder to the public of the importance of taking steps to eliminate breeding sources around their homes and to protect themselves from mosquito bites,” said Dr. Joe Iser, Chief Health Officer for the Health District.

Horses, like people, are susceptible to the virus through the bite of an infected mosquito.  Mosquitoes acquire the virus by feeding on infected birds.

The illness is not spread from person to person. Many people with the virus will have no symptoms or very mild clinical symptoms of illness. Mild symptoms include fever, headache, body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach, and back. In some cases, the virus can cause severe illness and even death.

Ongoing surveillance by the Health District has not detected Aedes albopictus or Aedes aegypti, the species known to spread the Zika virus as well as chikungunya and dengue.

Updated information on positive mosquito submission pools and mosquitoes that are tested in Clark County are posted on the Health District’s website.
