West Nile Activity Is Climbing Across the Northern San Joaquin Valley

Public-health officials are urging residents across the Northern San Joaquin Valley to stay alert as West Nile virus activity increases. Current regional reporting says confirmed human cases have been recorded in both Stanislaus and Merced counties, while mosquito-control agencies are also dealing with an aggressive invasive mosquito species.

For families, the practical message is simple: reduce standing water, repair window screens, use appropriate repellent, and pay attention to local mosquito-control notices. The story matters beyond one city because mosquitoes do not care where municipal boundaries end.

The Epic Gazette will continue treating health alerts like this as regional information instead of burying them inside one city's feed.
