The state health department says mosquitoes testing positive for the West Nile virus have been found in 13 Connecticut towns.
The state's Mosquito Management Program says the mosquitoes were trapped for testing between June 27 and July 18.
The first positive test was reported in mosquitoes trapped in Stamford on June 27, and health officials said Wednesday more West Nile mosquitoes have since been found in Fairfield County and other areas.
The 13 towns include Bethel, Danbury,Greenwich, East Haven, New Haven, Newington, Newtown, Norwalk, Stamford, Stratford, West Haven, Wallingford and Wilton.
No human cases have been reported, but nine were identified last year. Last year West Nile-infected mosquitoes were found in 30 municipalities.
People are urged to use insect repellent and protective clothing, especially at dawn and dusk when mosquitoes are most active.
