SANTA CLARA COUNTY, CALIF. - The Santa Clara County Vector Control District (SCCVCD) confirmed on June 27, 2011 that adult mosquitoes collected from the 94087 zip code area of Sunnyvale tested positive for West Nile virus (WNV). The detection of mosquitoes infected with WNV has prompted the scheduling of a mosquito fogging treatment in the surrounding area to prevent human cases of WNV. Weather permitting, the ground fogging is scheduled for Thursday, July 07, at 11:00 p.m., and is planned to last for several hours.
“While we observed a late start to the WNV season this year, we still have about 36 percent of all the WNV-positive birds in the State,” said Community Resources Specialist Jose Colome. “Control of infected adult mosquitoes is an essential component of preventing human cases of WNV and other mosquito-borne encephalitis.” The fogging area is generally bordered by Evelyn Avenue on the north, South Grape Avenue, Lime Drive and South Mary Avenue on the west, South Wolfe Road on the east, and Cascade Drive on the south.

Information packets will be distributed in the fogging area over the July 4th weekend, notifying residents about the fogging operation. As an added convenience, from July 5th through 7th, staff from the Santa Clara County Vector Control District and the Public Health Department will be available during extended hours from 7:30 am to 7:00 pm via a dedicated phone line/voicemail (800-314-2427) to answer questions and provide information.
Transmitted by mosquito bites, WNV causes mild to severe flu-like symptoms such as fever, headache, body aches, and, in severe cases, significant neurological damage or even death. The elderly and those with compromised immune systems are most susceptible. Since the arrival of WNV to California in 2003, 2,988 people across the State have contracted the disease; 101 of those cases were fatal.
“With above average temperatures coming over the July 4 weekend when many will be out and about, it is important for residents to take precautions to avoid being bitten by mosquitoes whenever they are outdoors,” said District Manager Russ Parman. “People can also help by draining standing water and reporting other sources of mosquito breeding such as neglected swimming pools.”
Some practical measures against mosquito bites are:
- DRAIN or DUMP standing water weekly since this is where mosquitoes lay eggs. Check items such as flowerpots and planter bases, toys, cans, leaky water faucets and sprinklers, rain gutters, buckets, pools, ponds, and old tires.
- Make sure your doors and windows have tight-fitting screens.
- Limit outdoor activities during DUSK & DAWN to prevent mosquito bites. Those are the times when the mosquitoes that transmit WNV are most active.
If you need to go outside at dusk or dawn, or when in an area where mosquitoes are active:
- DRESS in long sleeve shirts and long pants, preferably of light colors.
- Apply insect repellent following label instructions.
Always contact the Vector Control District if you are being bothered by mosquitoes or know of a potential mosquito-breeding source.
Dead birds may indicate the presence of WNV. The District has recently completed its new laboratory, which allows in-house testing for WNV and other vector-borne diseases throughout the year. The District asks Santa Clara County residents to report crows, jays, or birds of prey that have been dead for less than 48 hours and do not appear to have died because of an injury. People who find those birds should call the State of California WNV hotline at 877-WNV-BIRD (2473) or at www.westnile.ca.gov.
