Grant County detects West Nile in mosquitoes, urging bite-prevention measures

West Nile virus was detected in mosquitoes collected in Moses Lake, Grant County, with confirmation on June 29, 2026; officials warn that infected mosquitoes could be present elsewhere and urge residents to reduce standing water, seal homes against entry, and use EPA-registered repellents to prevent bites. Most infections are mild but severe illness can occur, especially for older adults or those with certain conditions. Grant County Mosquito Control District No. 1 continues trapping and control through October 2026; nearby counties have detections too, but no human WA cases in 2026 to date; last Grant County human case was in 2015.
