West Nile virus detected in Minnesota mosquitoes across three counties
West Nile virus has been detected in mosquitoes in three Minnesota counties (Hennepin, Ramsey, and Dakota) with samples from June 17 marking the first positives of 2026; the Metropolitan Mosquito Control District says it will boost surveillance and may expand treatments, while residents are urged to use repellent, cover exposed skin, and eliminate standing water to reduce bite risk, noting 2025 saw a record number of human cases statewide.
