West Nile Treatment Scheduled in Sunnyvale, Santa Clara

Santa Clara County disease control crews will treat neighborhoods in Santa Clara and Sunnyvale for West Nile virus Wednesday night after adult mosquitoes tested positive for the disease earlier this month.

The Santa Clara County Vector Control District, which monitors human diseases transmitted by parasites and bacteria, will conduct the treatment to prevent any human cases of West Nile virus.

The ZIP code areas of 94087, 95050 and 95051 will undergo the treatment for about three hours starting at 11 p.m., according to county officials. The ZIP codes include the areas of Santa Clara Central Park and Koreatown.

Residents do not need to relocate during the treatment but can close their doors and windows to avoid chemical contact.

Since the virus arrived to California in 2003, 292 people have died in the state due to the disease, according to county officials. There haven't been any cases in Santa Clara County since 2016 and the disease had its peak in 2014 with 10 human cases.

Dry weather and limited water resources are connected to the spread of West Nile virus, since birds are more likely to share water with mosquitoes and contract the disease.

Most people do not experience any symptoms if they become infected with the virus, but some rare cases include fevers, headache, neurological damage or death, according to county officials. Individuals over the age of 50 with chronic health conditions are more susceptible to West Nile virus.

County officials recommend dumping standing water where bugs can breed, and using tight-fitting screen doors and bug repellent to avoid contracting the disease.

Free mosquito removal services are available by calling the county at (408) 918-4770.
