Fogging to Suppress West Nile Virus Mosquitoes Scheduled for Wednesday, August 28 in San José

SAN JOSÉ, CALIF.  - The Santa Clara County Vector Control District (SCCVCD) confirmed on August 23 that adult mosquitoes collected from the 95123, 95133, 95127 and 95116 ZIP code areas of the city 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 Wednesday, August 28, at 11:00 p.m., and is planned to last for several hours.
“With this fogging the District will have treated almost 30 square miles of territory, which may be a record number in a single season,” said Acting District Manager Russ Parman. Residents across the County should continue to avoid mosquito bites and remove standing water from around the home.”
The fogging area is generally bordered by Berryessa Rd. on the north; N King Rd. on the west; Alum Rock Ave. on the south; and Rennie Ave. on the east.  A live map can be viewed at
Information packets will be distributed in the fogging area on Tuesday, August 27 and Wednesday, August 28 notifying residents about the fogging operation.  As an added convenience, on Tuesday and Wednesday from 7:30 a.m. to 7 p.m., staff from the SCCVCD will be available at (408) 918-3452 or (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 2003 arrival of WNV in California, 3,684 people across the State have contracted the disease; 134 of those cases were fatal.
“Using preventive measures such as insect repellent to avoid mosquito bites when outdoors can help decrease the risk of contracting this disease, and that’s especially important this season,” said Scientific / Technical Services Director Dr. Noor Tietze. “We haven’t seen this much virus activity since 2007, which was our last big year following the arrival of WNV in 2004.”
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. 
·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
