The detection of EEE in mosquitoes is a reminder of the potential for mosquito-borne illnesses, even late in the season. While the risk of human transmission is currently low, EEE is a serious and potentially fatal disease, with a 30% fatality rate among severe cases. Survivors may experience long-term neurological issues. The virus is primarily transmitted between birds and mosquitoes, but human cases can occur if the virus spreads to human-biting mosquito species. Residents in Connecticut, particularly in eastern areas like Colchester, are advised to remain cautious and take preventive measures.
