Summary
A man in his 90s exposed in Middlesex County became Massachusetts' first human West Nile case of 2026, prompting the state to lift risk levels to moderate in 70 communities.
180 mosquito samples have tested positive for West Nile this year across 13 counties, with infected mosquitoes also detected in Franklin and nearby communities.
State health officials warned the threat will persist until the first hard frost and urged residents to use EPA-registered repellent, cover exposed skin and avoid dusk-to-dawn outdoor activity.
The alert came a day after Eastern equine encephalitis was confirmed in 2 mosquito samples in Kingston, though no human or animal EEE cases have been reported this year.
