Release date: 
Jun 6

Cotati, CA.-The Marin/Sonoma Mosquito & Vector Control District (MSMVCD) has confirmed the second  West Nile virus (WNv) positive mosquito sample this year. The mosquitoes were collected in the vicinity of the Ellis Creek Water Recycling Facility in Petaluma. West Nile virus warning signs have been posted at access points into the water recycling facility.  

"The threat of West Nile virus is real and it is here," stated Nizza Sequeira, Public Relations Director for the MSMVCD. "However,this illness is preventable and by working together we can lessen the risk of WNV transmission," said Sequeira.

Residents are urged to report mosquito problems in their area 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.

In order to reduce the number of adult mosquitoes and break the virus transmission cycle, an adult mosquito control application is scheduled to occur this evening in the area where the positive mosquitoes were collected, weather permitting.

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

  • Cover rain barrels and other containers with a mosquito-proof screen (fine mesh-1/16 of an inch).
  • Check septic tank lids to ensure a tight seal, repair cracks and screen vent pipes using a fine mesh screen (1/16 of an inch).
  • 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.
  • 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.

 

Historical data regarding human cases of WNv have shown that less than 1% of people (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.
