West Nile fogging tonight

Mercury News

After discovering more West Nile virus-infected mosquitoes within a three-mile swath of San Jose and Campbell, Santa Clara County workers will start ``fogging'' the area with insecticide starting at 11 tonight.

The approximately 6,700 people living in the area have been notified, said Kriss Costa, vector control spokeswoman for the county.

The renewed mosquito control efforts come as the number of people infected with the potentially fatal disease has spiked statewide in the past few weeks. More infected birds have been reported in Santa Clara County than any other California county, according to statistics released Friday by the California Department of Health Services.

As of Friday, 38 human cases have been reported in the state this season, primarily in central California. Nearly half of the cases have been in Kern County, home to Bakersfield. Nationally, 192 human cases had been reported this year through Aug. 8, with Idaho reporting 45 cases, more than any other state.

Locally, insecticide fogging will occur in an area roughly bounded by Williams Road in San Jose, Winchester Boulevard in San Jose and Campbell, Century Drive and Budd Avenue in Campbell, and San Tomas Aquino Road and a small part of Saratoga Avenue in San Jose. Residents south of Century Drive and Budd Avenue are no longer in the fogging zone. More fogging may be scheduled later this week.

Costa said West Nile activity has picked up very quickly after a slow start this year. County workers already have detected 12 pools of infected mosquitoes this summer, compared with three pools at this time last year.

``It's just a matter of time that we should be getting our first human case,'' Costa said. ``We're trying to knock these mosquitoes down before they start feeding on humans. By taking care of them early, we can make big dent in the number of human cases in the future.''
