Cotati, Ca - The Marin/Sonoma Mosquito & Vector Control District (District) announced the first mosquito sample that has tested positive for West Nile virus in Sonoma County for 2016. The mosquito sample was collected near the Ellis Creek Water Recycling Facility in Petaluma. Both larval and adult mosquito control operations have been conducted in the immediate area to reduce the number of adult mosquitoes and break the virus transmission cycle. The District will continue to monitor the area for additional virus activity.
"As the temperatures rise we expect to see additional virus activity in both counties," stated Angie Nakano, Scientific Programs Manager for the Marin/Sonoma Mosquito & Vector Control District. "The warmer weather not only accelerates the life cycle of the mosquito, it amplifies the virus, making transmission much more likely," stated Nakano.
Residents are being urged to reduce exposure to mosquitoes and lessen the risk of West Nile virus by taking these precautions:
- Avoid being outdoors during peak mosquito activity (dawn and dusk).
- Use mosquito repellents containing DEET, picaridin or oil of lemon eucalyptus (always carefully read and follow the directions on the label!)
- Wear protective clothing such as long sleeves and long pants.
- Keep doors and windows closed whenever possible.
- Check and maintain all window and door screens.
- Contact the Marin/Sonoma Mosquito & Vector Control District (707-285-2200) if you have a mosquito-related problem that you cannot resolve on your own.
- Continue to report dead birds to the West Nile Virus hotline at 1-877-WNV-BIRD or online.
