Sep 12

 

Cotati, CA-The Marin/Sonoma Mosquito & Vector Control District announced today that additional West Nile virus (WNV) activity has been detected in Sonoma County. Mosquitoes trapped near Millbrae Avenue and Langner Avenue in Santa Rosa have tested positive for WNV.

In addition, four dead birds have tested positive for WNV; a western scrub-jay from the vicinity of Jack Pine road and Odom road in Healdsburg, another western scrub-jay from the vicinity of Benjamin Way and North Fitch Mountain Road in Healdsburg, an American crow from the vicinity of Baker Lane and Edwards Lane in Sebastopol, and another American crow from the vicinity of Belair Way and Marsh Road in Santa Rosa. 
 
Residents are urged to report mosquito problems in their areas and to reduce mosquito production sites in their yards by removing standing water on a regular basis.  Most importantly, residents should use personal protection measures against mosquito bites. Wearing long sleeved shirts, long pants and applying an effective repellent to exposed skin will help reduce the risk of WNV transmission from an infected mosquito.

 

2014 West Nile virus activity:

 

Marin County: 3 dead birds and 3 mosquito samples have tested positive for West Nile virus to date.

 

Sonoma County: 19 dead birds, 6 mosquito samples, 1 equine case, and 1 sentinel chicken have tested positive for West Nile virus to date.

 

Simple ways to help reduce exposure to mosquitoes and lessen the risk of WNV:

  • Eliminate standing water in rain barrels, old tires, buckets, kiddie pools or any other item that can hold water for more than 72 hours. 
  • Check septic tank lids to ensure a tight seal and repair any visible cracks.
  • Screen septic tank vent pipes using a fine mesh screen.
  • Report mosquito problems, neglected swimming pools, or any area that could be producing mosquitoes at  www.msmosquito.com or 1-800-231-3236.
  • Stock backyard ponds or other permanent water features with mosquitofish. 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 or online at www.westnile.ca.gov.
  • 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. 
  • Residents interested in staying informed about district activities are encouraged to follow MSMVCD on twitter and facebook.
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.

  

The Marin/Sonoma Mosquito and Vector Control District is an independent special district committed to protecting public health from mosquitoes and vector-borne disease. All programs and services are funded through benefit assessments and property taxes. Services are provided to all residents in Marin and Sonoma counties.
