Coachella Valley, CA: The Coachella Valley Mosquito and Vector Control District detected additional West Nile Virus (WNV) positive samples in the eastern Coachella Valley. Samples from routine collection sites in Thermal and Oasis tested positive for WNV for the first time in 2024. Samples in Mecca were also positive for WNV. This week’s results bring the year’s total WNV positive samples to eighteen. At this time last year, no virus activity was detected in the Coachella Valley.

The Coachella Valley Mosquito and Vector Control District has scheduled additional mosquito control treatments in the area, including adult mosquito control treatments by helicopter. The aerial application is within the boundaries of Avenue 68 (north), Grant St. (east), Avenue 74 (south), and Buchanan St. (west).

The District will continue enhanced mosquito surveillance to reduce the number of mosquitoes and interrupt further transmission of the virus. Additional mosquito and treatment information can be found on our website.

“We have been doing a lot of additional work in the area,” said Jeremy Wittie, General Manager for the District. “But remember to protect yourself to minimize your risk. Limit time outdoors at dawn and dusk and don’t skimp on the repellent.”

No human cases of WNV have been reported in the Coachella Valley or the state this year. There is no human vaccine for West Nile Virus. Residents should be proactive against mosquito bites by using EPA-registered insect repellent containing at least thirty percent of an active ingredient like DEET, picaridin, oil of lemon eucalyptus, or IR3535, not essential oils.

About West Nile Virus: WNV spreads when a female mosquito bites an infected bird. The mosquito then can become a carrier and transmit the virus to people. Most infected people will have no symptoms. Others will develop fever, headaches, and body aches; hospitalization is required in some cases, and in rare cases, death occurs. People with symptoms should contact their health care provider.

Prevent mosquito bites: 

  • Don’t go outside around dawn and dusk when these mosquitoes are most active.
  • Wear insect repellent. EPA registered ingredients such as DEET, picaridin, oil of lemon eucalyptus, or IR3535 (as directed on the product label).
  • Cover up. Wear long sleeve shirts and long pants when mosquitoes are most active.
  • Check window and door screens to prevent mosquitoes from entering your home.

Prevent mosquitoes around your home:

  • Check lawn drains for water and debris. Clean drains regularly.
  • Inspect yards for standing water sources. Drain water that collects under potted plants, bird baths, tires, and any other water holding containers.
  • Clean and scrub pet dishes and water features weekly.
  • Swimming pools, ponds, and fountains require working pumps and regular maintenance.
