Fogging to Suppress West Nile Virus Mosquitoes Scheduled in San José

SANTA CLARA COUNTY, CALIF.  - The Santa Clara County Vector Control District (SCCVCD) confirmed on 9/11/2012 that adult mosquitoes collected from the 95123 ZIP code area of San José 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, in an effort to prevent human cases of WNV.  Weather permitting; the ground fogging is scheduled for Saturday, September 15th, at 11:00 pm, and is planned to last for several hours.
 
Director of Environmental Health Scott Bourdon notes that “Nationally, this is one of the worst years for West Nile Virus since it was originally detected in the United States.  Human case loads are surging in other states. With 92 human cases in 18 California Counties, these operations are intended to prevent human cases from occurring locally.” 
 
The fogging zone is generally bordered by Blossom Hill Rd., Ave Del Roble, Coy Dr. and Hayes Ave. on the north; Entrada Cedros, Chesbro Ave. and Hancock Ave. on the west; Walnut Blossom Dr., Beswick Dr., Cottle Rd. and Woosley Dr. on the east; and Colleen Dr., Curie Dr. and Los Pinos Wy on the south.  A live map, which includes a 300 foot buffer around the fogging zone, can be viewed at http://goo.gl/maps/a79Ig.
 
Information packets will be distributed in the fogging area on September 14th and 15th, notifying residents about the fogging operation.  As an added convenience, on September 14th and 15th, 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 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, 3,146 people across the State have contracted the disease; 110 of those cases were fatal.
 
Scientific/Technical Services Director Dr. Noor Tietze said, “It is important for residents to take precautions to avoid being bitten by mosquitoes whenever they are outdoors, especially during dusk and dawn. 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:
 
At home:
·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. 
 
Outdoors:
·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 and often lead to detection of mosquitos carrying the virus.  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 westnile.ca.gov.
 
Residents can visit the District’s website at sccVector.org to view a map of the fogging zone, read the latest alerts about WNV activity in the County, and request advice or services.
