Cotati, CA -The Marin/Sonoma Mosquito and Vector Control District (MSMVCD) has confirmed the first dead bird infected with West Nile virus (WNV) in Marin County for 2014. The bird, an American crow, was found near Oak Park Drive and Orange Avenue in Novato.


Residents are urged to take the threat of WNV seriously and continue to take the necessary steps to protect themselves from mosquitoes and mosquito bites. Mosquito problems can be reported online at www.msmosquito.com or by calling 1.800.231.3236.


Simple ways to help reduce the threat of WNV: 

  • Eliminate standing water in rain barrels, old tires, buckets, kiddie pools or any other item that can hold water for more than a week.
  • Report mosquito problems, neglected swimming pools, or any area that could be producing mosquitoes.
  • Stock backyard ponds or other permanent water features withmosquitofish. The fish are free and can be delivered or simply picked up at the District office.
  • Report dead birds to the West Nile virus hotline at 1-877-968-2473.
  • Wear mosquito repellent when outdoors at dusk and dawn. Use a repellent containing one of the following active ingredients: DEET, Picaridin, oil of lemon eucalyptus, or IR3535.

West Nile virus is a mosquito-borne disease that is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread the disease to humans and other animals.


Less than 1% of people (about 1 in 150) infected with WNV develop serious illness. These cases may last for extended periods of time, result in permanent neurological damage and may be fatal.  


Approximately 20% of people (about 1 in 5) infected with WNV experience mild symptoms that may include fever, headache, body aches, nausea, rashes, swollen lymph nodes and vomiting. Approximately 80% of people (about 4 out of 5) infected with WNV do not show any symptoms.
