Napa County Confirms West Nile Virus | San Francisco News

Napa County confirms its first West Nile Virus case since 2023 after a dead crow tested positive in July — a warning sign the virus is back. Spread by Culex mosquitoes that bite infected birds and then humans, it’s not contagious between people or birds. With 2 human cases and over 670 mosquito samples positive across California this year, and this crow being the 205th bird case statewide, the virus is active — even if not widespread. Stay safe by eliminating standing water, using repellent at dawn/dusk, checking screens, and reporting dead birds via westnile.ca.gov/report or 1-877-968-2473.
