With hot weather, risk of West Nile Virus continues

HARTFORD, Conn. (WTNH) — The State Mosquito Management Program is reminding Connecticut residents the risk of acquiring West Nile Virus continues as warm weather remains.

They announced Thursday that mosquitoes trapped and tested by the Connecticut Agricultural Experiment Station continue to be positive for West Nile Virus due to the current warm weather.

“The current warm weather provides favorable conditions for the mosquitoes that transmit West Nile virus,” said Dr. Philip Armstrong, Medical Entomologist at the CAES. “These mosquitoes are most active at nighttime when temperatures are higher than average.”

“In recent weeks the CAES has reported an increasing number of infected mosquitoes especially at trap sites in coastal towns,” said Dr. Randall Nelson, infectious disease epidemiologist with the Connecticut Department of Public Health.

Going into the holiday weekend, the DPH is reminding everyone to take steps to prevent mosquito bites. Although no human cases of WNV infection have been reported this year, the numbers of WNV infected mosquitoes responsible for transmission of the virus to people that have been trapped recently exceed the historical weekly averages.

During 2015, WNV-positive mosquitoes have now been identified in 19 towns: Bridgeport, Cheshire, Chester, Darien, East Haven, Glastonbury, Greenwich, Groton, Guilford, Hartford, New Haven, Norwalk, Stamford, Stonington, Stratford, Waterford, West Haven, Westport and Wethersfield. Of the 19 towns, 14 are located along Long Island Sound in Fairfield (7), New Haven (4) and New London (3) counties.
