Posted on: July 10, 2023 - 12:51pm

A sample of mosquitoes from a routine collection site in Northshore tested positive for St. Louis Encephalitis Virus (SLEV) near Arthur Street and 72 Avenue for the first time this year. This is the 36th sample from the valley to test positive for virus in 2023.

The Coachella Valley Mosquito and Vector Control District will provide mosquito control treatments Wednesday, Thursday, and Friday July 12-14. Applications are planned between 1:00 a.m. and 7:00 a.m., weather permitting.

The application area is within the boundaries of 68th Avenue, Arthur Street, the Salton Sea shoreline, and Buchanan Street. Residents can check the District website for application routes and updated application times.

“We have been doing a lot of additional work in the area,” said Tammy Gordon, Public Information 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 mosquito-borne illness have been reported by the Coachella Valley Mosquito and Vector Control District. One human case of SLEV has been reported in the state this year.

Prevent mosquito bites: 

·      Stay inside at 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, birdbaths, 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.

About St. Louis Encephalitis Virus. SLEV 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.
