Placer Mosquito & Vector Control warns Lincoln residents: West Nile surveillance rising; invasive Aedes found in neighborhoods

Placer Mosquito and Vector Control District presented its annual update to the Lincoln City Council on June 10, reporting that as of the district’s last update there were no West Nile virus detections in Placer County but state surveillance showed an increasing number of positive dead birds and mosquito samples.

The district’s public information officer, Megan Lovano, said the statewide picture is beginning to show virus circulation — "as of today ... we have not found it in any dead birds, any mosquito samples. There's no human cases. But in the state, there's been 13 positive dead birds and 74 positive mosquito samples." She told council that dead-bird reports are an early indicator: a handful of positive dead birds is often followed by positive mosquito samples a week or two later.
