SHASTA COUNTY, Calif. - The Shasta Mosquito and Vector District Control confirmed the first cases of West Nile virus activity in Shasta County on Saturday.
The positive tests were confirmed in the Anderson and Shingletown areas.
The adult mosquito samples are collected routinely by the district as part of its surveillance program.
“These positive samples are earlier when compared to previous years, but the higher temperatures can increase virus transmission rates in mosquitoes,” District Manager Peter Bonkrude said.
