West Nile virus discovered in Santa Clara County, here’s how to avoid it


West Nile virus has been discovered in Santa Clara County.

KRON4’s Sara Stinson is in Sunnyvale with details on how the country is planning to combat the virus.

She says two dead crows tested positive for the disease in the last week.

The county’s vector control has since been able to trap and test mosquitoes in the area.

County officials will begin treatment tonight in three different zip codes in Santa Clara and Sunnyvale. 

There hasn’t been a human case in Santa Clara county since 2016.

In 2015 there was ten cases, but the peak was in 2014 – due to very dry weather when birds were sharing water with mosquitoes.

“I am surprised it’s back in the area, it’s been a long time,” Sunnyvale resident Ana Vallejos tells KRON4. “I remember the last time it was frightening and we took a lot of precautions too didn’t want to be outside.”

Ana says she received a notice on her door about the spraying, which is set to begin at 11:00 p.m. tonight in zip codes 94085, 95051 and 95054. This is centered in the area of Central Expressway and Semiconductor Drive in Santa Clara.

Residents do not need to leave their homes during the treatment, but may want to close windows and doors to avoid possible chemical sensitivity.

To avoid contracting the disease, people are recommended to dump any standing water around their home and use mosquito repellent.
