Samples of mosquitoes from routine collection sites have tested positive for West Nile virus (WNV) in two new areas of Coachella Valley, California. This year, four mosquito samples have been found to carry the virus, whereas no detections were reported at this time last year.
In Indio, the detection was made from a trap near Madison Ave and Ave 38. In Mecca, two mosquito traps detected the virus. These traps are located near Buchanan St and Ave 68, and Lincoln St and Ave 72.
Despite these findings, no human cases of WNV have been reported in the Coachella Valley. In response to the detections, staff from the Coachella Valley Mosquito and Vector Control District are posting disease notification signs in communities located near the traps. They will also increase mosquito surveillance and control treatments in these areas to reduce the number of mosquitoes and interrupt further transmission of the virus.
West Nile Virus spreads when a female mosquito bites an infected bird, becoming a carrier that can transmit the virus to people. While most infected individuals will experience no symptoms, others may develop fever, headaches, and body aches. Hospitalization is required in some cases, and death can occur in rare instances. Individuals experiencing symptoms should contact their healthcare provider.
To prevent mosquito bites:
- Avoid going outside around dawn and dusk when mosquitoes are most active.
- Wear insect repellent with EPA registered ingredients such as DEET, picaridin, oil of lemon eucalyptus or IR3535.
- Cover up by wearing long sleeve shirts and long pants when mosquitoes are most active.
- Check window and door screens to prevent mosquitoes from entering your home.
To prevent mosquitoes around your home:
- Regularly check lawn drains for water and debris.
- Inspect yards for standing water sources 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 regular maintenance.
