West Nile Virus Detected in Clark County Mosquitoes

By TheNevadaGlobeStaff, May 25, 2024 1:12 am

The Southern Nevada Health District (SNHD) has identified the first West Nile virus-positive mosquitoes in Clark County for 2024. The infected mosquitoes were trapped and tested within the 89031 and 89032 ZIP codes.

This detection comes after more than 9,000 mosquitoes have been tested so far this year.

Public health officials are particularly concerned about the rise of Aedes aegypti mosquitoes in Clark County. Unlike most local mosquitoes, Aedes aegypti are aggressive daytime biters that target humans rather than birds. These persistent ankle-biters, with a single female capable of inflicting multiple bites, pose a greater risk of transmitting West Nile virus.

Since their initial discovery in Clark County in 2017, the presence of Aedes aegypti mosquitoes has steadily increased. From just four ZIP codes in 2017, their range expanded to 12 in 2022 and a significant 43 in 2023.

The SNHD is urging residents to participate in the “Fight the Bite” campaign. This program encourages residents to:

  • Eliminate standing water sources around their homes and properties.
  • Take appropriate precautions to avoid mosquito bites, such as wearing repellent and long sleeves and pants when outdoors.
  • Report mosquito activity to the SNHD mosquito surveillance program at 702-759-1633.

By taking these steps, residents can help reduce the risk of West Nile virus transmission in Clark County.
