Mosquitoes have tested positive for West Nile Virus in four Connecticut towns, including Ridgefield, according to the latest data from the Agricultural Experiment Station. That brings the total to 16 towns so far this season.
One mosquito trapped in Ridgefield at Great Swamp tested positive earlier this month.
Entomologist Dr Philip Armstrong says Fairfield, New Haven and Hartford counties tend to see West Nile activity because the mosquito that transmits the virus is most concentrated in urban and suburban environments. Last season, West Nile was detected in 143 mosquito pools from 21 towns. There were 8 cases confirmed in people statewide last year, and no human cases this season.
People are urged to take precautions against mosquito bites such as wearing long-sleeved shirts, pants, and shoes and socks, applying an EPA-approved insect repellent, and minimizing time outdoors when mosquitoes are most active.
