Fogging to Suppress West Nile Virus Mosquitoes Scheduled in San José

SAN JOSÉ, CALIF. - The Santa Clara County Vector Control District (SCCVCD) confirmed on July 5 that adult mosquitoes collected from the 95123 and 95136 (partial) ZIP code areas 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 Thursday, July 11, at 11:00 pm, and is planned to last for several hours.
