Adult mosquitoes collected in Los Altos, Los Altos Hills and Mountain View tested positive for West Nile virus prompting officials to plan for a ground fogging on Thursday.
Mosquitoes were collected from ZIP code areas 94024 and 94040 and the virus was confirmed on Friday, according to a press release from the Santa Clara County Vector Control District (SCCVCD).
SCCVCD will fog the areas generally bordered by Rosita Avenue, Glen Alto Drive, Arboleda Drive, Cuesta Drive, and Eunice Avenue on the north. Campbell Avenue, La Prenda Road, Quinnhill Road, and Casa Mia Way on the west; Truman Avenue, Malbarough Avenue, Wessex Avenue, Austin Avenue and Grant Road on the east; and 280 Freeway and Saint Joseph Avenue on the south.

"While we're seeing a slow start to the (West Nile) virus season this year, the detection of virus in mosquitoes—in this case one in 75 mosquitoes were infected—represents a direct risk of human infection," said Scott Bourdon, director of the Department of Environmental Health in a statement. "Control of infected adult mosquitoes is an essential component of preventing human cases and other mosquito-borne encephalitis."
Transmitted by mosquito bites, West Nile Virus 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.
The fogging will begin at 11 p.m. on Thursday and is planned to last for several hours.
Residents in the effected fogging areas will receive printed information about the fogging, and district staff will be available to answer questions during extended hours from 7:30 a.m. to 7 p.m. on Wednesday and Thursday on a dedicated phone line/voicemail at 800-314-2427.
