Mosquito samples from a routine collection site in Indian Wells, California, have tested positive for West Nile virus (WNV) for the first time this year. The sample was located near the intersections of Fred Waring Drive and Eldorado Drive. This marks the 182nd sample from the Coachella Valley to test positive for WNV in 2024.
District staff have posted disease notification signs in communities where virus activity was detected and have intensified mosquito surveillance and control measures in the surrounding areas. Technicians are also conducting larval and adult mosquito control as necessary to reduce mosquito populations and interrupt further transmission of the virus.
No human cases of mosquito-borne illness have been reported in the Coachella Valley in 2024. “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. People over the age of 50 and individuals with lowered immune systems are at greater risk of suffering severe symptoms of WNV.
The District urges residents to be proactive against mosquitoes by wearing 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. To reduce mosquito numbers, residents must eliminate standing water where mosquitoes can breed. This includes draining water-holding containers and low-lying landscape areas where water can collect, such as pet dishes, plant saucers, and unmaintained pools.
West Nile Virus spreads when a female mosquito bites an infected bird. The mosquito then becomes a carrier and can transmit the virus to people. Most infected individuals will exhibit no symptoms; however, some may develop fever, headaches, and body aches. Hospitalization is required in certain cases, and in rare instances, death may occur. People exhibiting symptoms should contact their healthcare provider.
