West Nile Virus Activity Update: Marin County

Release date: 
Aug 12
Cotati, Ca - The Marin/Sonoma Mosquito & Vector Control District (District) announced finding a dead American crow infected with West Nile virus. This is the third dead bird to test positive for the virus in Marin County so far this year. The bird was collected from Novato in the vicinity of Feliz Road and Simmons Lane. The District will continue to monitor the area for additional virus activity. 

"While we continue to monitor for invasive species that may vector the Zika virus, it is important to remember that local mosquitoes can also carry potentially fatal diseases, such as West Nile virus. We encourage the public to report dead crows, ravens and jays for West Nile virus testing. Early evidence of virus activity helps us target our efforts to break up virus transmission cycles before people get sick," stated Angie Nakano, Scientific Programs Manager for the Marin/Sonoma Mosquito & Vector Control District.   
 
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.
