The detection of West Nile Virus (WNV) positive mosquito samples continues in the Coachella Valley. For the first time in 2024, mosquitoes from routine collection sites in southeast La Quinta and Palm Desert tested positive. The samples were collected from traps near Madison St. and Avenue 52 (La Quinta), Monroe St. and Ave 60 (La Quinta), and Fred Waring Dr. and Warner Trail (Palm Desert). Additionally, a trap in Indio at Jackson and Avenue 50 yielded one positive sample. Multiple traps in Mecca, Thermal, and Oasis also continued to show positive results this week.
In total, WNV-positive mosquitoes have been detected in four cities and four unincorporated areas so far this year. District staff have posted disease notification signs in affected communities and intensified mosquito surveillance and control measures. This week’s results have doubled the number of positive detections, bringing the total to 91 for the year, compared to zero at this time last year.
“West Nile virus is the leading cause of mosquito-borne disease in the United States; detections like this should serve as a strong reminder to wear insect repellent anytime we are outdoors,” said Antonio Molina, Field Supervisor for the District.
Residents are urged to take proactive measures against mosquitoes by using EPA-registered insect repellents containing at least thirty percent of an active ingredient such as DEET, picaridin, oil of lemon eucalyptus, or IR3535—not essential oils—and ensuring there is no standing water around their homes. Homeowners should also reduce or eliminate irrigation runoff that may accumulate in neighborhood catch basins.
To prevent mosquito bites:
– Avoid going outside around dawn and dusk when mosquitoes are most active.
– Wear insect repellent with EPA registered ingredients like DEET, picaridin, oil of lemon eucalyptus, or IR3535.
– Check window and door screens to keep mosquitoes out of your home.
To prevent mosquitoes around your home:
– Regularly check lawn drains for water and debris.
– Inspect yards for standing water sources; drain water that collects under potted plants, bird baths, tires, or other containers.
– Clean pet dishes and water features weekly.
– Ensure swimming pools, ponds, and fountains have working pumps and receive regular maintenance.
West Nile Virus spreads when a female mosquito bites an infected bird. The mosquito can then transmit the virus to humans. Most infected individuals will exhibit no symptoms; however, some may develop fever, headaches, or body aches requiring hospitalization. In rare cases, WNV can be fatal. People experiencing symptoms should contact their healthcare provider.
