Mosquitoes With West Nile Virus Trapped In Indio & Mecca; Still No Human Cases Of The Virus In The Desert This Year

Samples of mosquitoes from routine collection sites tested positive for West Nile virus (WNV) in two new Coachella Valley areas. So far this year, four mosquito samples have tested positive for the virus. At this time last year, we had no detections of virus activity.

In Indio, the detection came from a trap near Madison Ave and Ave 38. In Mecca, two mosquito traps detected the virus. Locations of these traps are near (1) Buchanan St and Ave 68, and (2) Lincoln St and Ave 72.

No human cases of WNV have been reported in the Coachella Valley.

The Coachella Valley Mosquito and Vector Control District staff are posting disease notification signs in communities located near the traps and will increase mosquito surveillance and control treatments in the area to reduce the number of mosquitoes and interrupt further transmission of the virus.

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.
