SAN JOSÉ, CALIF.  - The Santa Clara County Vector Control District (SCCVCD) confirmed today that adult mosquitoes collected from the 95035, 95131 and 95132 ZIP code areas of the cities of Milpitas and San José tested positive for West Nile virus (WNV).
The detection of mosquitoes infected with WNV has prompted the scheduling of mosquito fogging treatment, in an effort to prevent human cases of WNV.  Weather permitting, ground fogging operations are scheduled for Wednesday, September 11, at 11:00 p.m., and are planned to last for several hours.
“September is a time when WNV can remain quite active,” said Acting District Manager Russ Parman. “Residents should continue to avoid mosquito bites and call in any dead birds sighted.”
The fogging area is generally bordered by Fallen Leaf Dr., Great Mall Pkwy., Montague Expy., and Landess Ave. on the north; Hostetter Rd. on the south; Fwy. 880 on the west; and Morrill Ave. and Trudean Way on the east.  A live map can be viewed at 
Information packets notifying residents of the fogging operation will be distributed in the fogging areas starting on Tuesday, September 10.  As an added convenience, from 7:30 a.m. to 7 p.m. on Tuesday and Wednesday 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, 3,726 people across the State have contracted the disease; 136 of those cases were fatal.
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
