Another Dead Bird Tests Positive for West Nile Virus in Marin County

Release date: 
Jul 7

Cotati, Ca - Just one week after announcing the first West Nile virus positive dead bird of the year, the Marin/Sonoma Mosquito & Vector Control District (District) has identified additional virus activity. An American crow collected from the City of Novato (in the vicinity of Laurelwood Drive and Silver Maple Place) has tested positive for the virus. Vector control technicians have checked surrounding areas for sources of mosquito production and will continue to monitor virus activity through additional surveillance measures. Thus far, adult mosquitoes trapped and tested from the immediate area have not tested positive for West Nile virus.

Residents are encouraged to join the fight against mosquitoes by reducing mosquito production on their own properties:

  • Cover rain barrels and other containers with a mosquito-proof screen (fine mesh-1/16 of an inch).
  • Continue to report dead birds to the West Nile Virus hotline at 1-877-WNV-BIRD or online.
  • Check septic tank lids to ensure a tight seal and repair any visible cracks.
  • Recycle old tires or store in a sheltered area, away from the rain.
  • Inspect areas around your property for containers holding water and dump or drain.
  • Report mosquito problems, neglected pools, or any area that may be producing mosquitoes at or at 707-285-2200.
  • Stock backyard ponds or other permanent water features with mosquitofish.
