West Nile Virus Positive Mosquitoes Confirmed in East Valley

This is the first positive West Nile virus mosquito sample in Thermal this year.

Posted on: June 8, 2022 - 12:33pm

Mosquitoes collected in Thermal tested positive for West Nile Virus (WNV) near Avenue 68 and Fillmore Street.

The Coachella Valley Mosquito and Vector Control District is increasing mosquito control technicians in these areas and will carry out mosquito control treatments as needed to reduce the number of mosquitoes and interrupt further transmission of the virus.

“Before going out, apply insect repellent containing the EPA-registered ingredients.” said Tammy Gordon, Public Information Officer for the District. “At least thirty percent of an active ingredient like DEET, picaridin, oil of lemon eucalyptus, or IR3535 is best, not essential oils. There is no cure or vaccine for West Nile virus, it’s not worth getting sick.”

No human cases of mosquito-borne illness have been reported in the Coachella Valley or the state this year.

About West Nile Virus

WNV is spread 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 mosquitoes around your home:

  • Check for overwatering. Clean lawn drains regularly and reduce or eliminate landscape irrigation run-off to the street.
  • Inspect yards for standing water sources. Drain water that collects under potted plants, birdbaths, tires, and any other water holding containers.
  • Clean and scrub pet dishes and water features weekly.

Prevent mosquito bites: 

  • Don't go outside around dawn and dusk when mosquitoes are most active.
  • Wear insect repellent with EPA registered ingredients.
  • Cover up. Wear long sleeve shirts, pants, socks, and shoes when mosquitoes are most active.
  • Check window and door screens to prevent mosquitoes from entering your home.
