Parts of Sunnyvale and Santa Clara will be sprayed late Thursday night as part of a mosquito eradication effort to protect against the spread of West Nile virus.
The Santa Clara County Vector Control District scheduled the 11 p.m. truck-mounted mosquito control treatment after determining that a sampling of adult mosquitoes near Sunnyvale and Santa Clara had tested positive for the virus.
West Nile virus is transmitted to humans by mosquitoes and can cause mild to severe flu-like symptoms, such as fever, headache and body ache. In severe cases, the virus can cause significant neurological damage and even death, according to the district.
