The State of Connecticut Mosquito Management Program announced that mosquitoes trapped in Mianus River Park have tested positive for West Nile Virus (WNV). These are the first positive mosquitoes identified by the Connecticut Agriculture Experiment Station (CAES) in Greenwich this year. In addition to Greenwich, WNV positive mosquito pools have been found in Darien, Milford, New Haven, South Windsor, Stamford and Waterford. The mosquitoes trapped (Culex pipiens, Culex restuans) are generally bird and mammal biting which breed in standing water often found in artificial containers like discarded tires, birdbaths and catch basins. During 2020, eight (8) Connecticut residents developed WNV-associated illness including two (2) Greenwich residents, the cases were not fatal. So far this year EEE has not been isolated in mosquitoes in Connecticut. The State Mosquito Management Program continues to trap and test mosquitoes at three testing sites in Greenwich as part of their program and will continue through October 2021.
