The Santa Clara County Vector Control is scheduled to spray portions of Mountain View and Sunnyvale tomorrow night with a mosquito-control pesticide in an attempt to curb the spread of the West Nile virus. The "fogging" is set to take place Tuesday (Aug. 19) from 11 p.m. to 2 a.m.
The fogging area lies between Highway 237 and Central Expressway to the north; W. Remington Drive to the south; Mathilda Avenue, S. Taaffe Street and Spinosa Drive to the east; and Highway 85 to the west.
Mosquitoes infected with the virus have been collected from the zip codes 94086, 94087, 94040 and 94041, prompting the vector control agency to schedule the fogging.
Five residents of Santa Clara County have been infected with the West Nile virus, including two who developed the severe neuroinvasive form that can lead to death, according to a county spokeswoman.
According to Noor Tietze, the vector control agency's scientific and technical services manager, the fogging treatment will take place at night because at that time mosquitoes are more active, traffic is lighter, fewer people are out and bees are more likely to be in hives.
Tietze said that the agency uses five pick-up trucks -- four with an electric motor and one with a gas-powered spray machine -- to deliver the treatment. According to Tietze, the treatment involves use of the pesticide Zenivez, which is not toxic to people or pets.
Tietze said that most people infected with West Nile virus nationwide do not report symptoms, but that some people infected with the virus do experience fevers and some may suffer serious illness or death.
