SONORA—On July 30, 2018, the Tuolumne County Public Health Department announced the first confirmed human illness in Tuolumne County due to West Nile virus (WNV).

On September 4, 2018, a dead California Scrub Jay bird was found in Sonora, and the dead bird was tested for WNV infection – the result was positive as reported on September 21, 2018. The detection of WNV in a dead bird provides an early signal that mosquitos carrying the WNV are present in our environment, and an early warning that it is important to take protection against mosquito bites:
