Overview
- Davis County officials reported a local mosquito pool tested positive for West Nile virus, triggering public warnings and urging residents to remove standing water and use repellent.
- Fort Bend County has confirmed 32 West Nile–positive mosquito samples, declared a public health emergency and completed targeted aerial spraying with final effectiveness results still pending.
- County crews in Fort Bend are conducting repeated nighttime ground spraying in areas with positive pools and say they begin ground treatments when a positive mosquito pool is detected.
- Health authorities confirmed two human West Nile cases in the Houston area — one in Harris County and one in Montgomery County, with Montgomery reporting its first 2026 case — and officials stress most infections are mild while rare neurological illness can be severe.
- Officials urge the public to follow proven steps to reduce risk: limit outdoor time at dawn and dusk, wear long clothing, use EPA‑registered repellents and remove standing water, because routine mosquito trapping and testing serve as early warnings that guide spraying and testing decisions.
