Milford mosquito samples trapped June 29 produced Connecticut’s first West Nile virus detection of the summer, state officials said Tuesday.
Recent rainfall, high humidity and warm temperatures are expected to boost mosquito activity and virus buildup in the coming weeks, with monitoring set to continue through October.
State health officials urged residents to use repellent, cover bare skin and limit outdoor time at dusk and dawn, when mosquitoes are most active.
Last year, Connecticut found West Nile virus in 230 mosquito samples across 37 towns in six counties; in 2025, six residents were hospitalized and one died.
