SUTTER COUNTY (CBS13) – There is now an elevated risk of West Nile Virus in Sutter County after a second sample of mosquitoes has tested positive, the Sutter-Yuba Mosquito and Vector Control District announced on Friday.

“If you’re going to be outside anywhere in Yuba and Sutter Counties when mosquitoes are active, please don’t take any chances and protect yourself by applying a good mosquito repellent and by wearing long sleeves and pants at dawn and dusk when mosquito activity is high,” said Stephen Abshier, District Manager.
