ROSEVILLE (CBS13) — Vector control officials say a mosquito sample in Placer County has tested positive for West Nile virus.
The Placer Mosquito and Vector Control District announced the county’s first positive sample on Wednesday. It was taken from a mosquito trap in the western part of the county, near Baseline and Pleasant Grove roads.
Health officials have already confirmed positive West Nile samples in nearly a dozen other California counties this season. Back in late June, Stanislaus County also confirmed two human cases of the virus.
