(WTNH) — Even with the cooler weather, state health officials are continuing to warn residents about the mosquito-borne eastern equine encephalitis (EEE) virus.

“Although mosquito numbers are on the wane, we continue to detect EEE virus in mosquitoes, some of which are being found in new communities,” said Dr. Philip Armstrong, Medical Entomologist at the Connecticut Agricultural Experiment Station (CAES). “We will continue to closely monitor the situation by trapping and testing mosquitoes for EEE throughout the State until the first killing frost.”

The EEE virus has been detected this season in 27 Connecticut towns:

  • North Stonington
  • Old Lyme
  • Plainfield
  • Salem
  • Shelton
  • South Windsor
  • Stamford
  • Sterling

Three fatal human cases were found this season in Old Lyme, East Haddam and East Lyme.

A Colchester resident has a confirmed case of EEE and is still in the hospital after several weeks of treatment.

On Oct. 7, more mosquitoes tested positive for EEE in East Lyme. Experts said they pose less of a threat to humans because they’re mostly bird-biting.

Bird-biting mosquitoes carrying EEE were also recently detected in Groton and Waterford.

The Connecticut Agricultural Experiment Station (CAES) continues to test bugs across the state for EEE as well as for West Nile Virus.

Several towns across the state have encouraged residents to follow suggested dawn and dusk curfews to protect them from being bitten. Municipal and school events have been rescheduled to avoid mosquitoes at dawn and dusk.

The EEE virus has been detected in 27 Connecticut towns in the 2019 season. There have been four human cases (three fatal), 6 horse cases, and one bird case as of Oct. 16 2019. Map: CAES
