Mosquitoes in another Connecticut community have tested positive for Eastern Equine Encephalitis.
On Monday the Ledge Light Health District announced a mosquito trapped in East Lyme tested positive for EEE.
The deadly virus has claimed three lives and sickened a fourth person. One of the people who died is from East Lyme. The other cases were reported in residents from Colchester, East Haddam and Old Lyme.
According to the latest state data, EEE has been detected in mosquitoes in 20 towns - Bethany, Chester, Groton, East Lyme, Haddam, Hampton, Killingworth, Ledyard, Lyme, Madison, Middlefield, North Stonington, Old Lyme, Plainfield, Shelton, South Windsor, Stamford, Stonington, Voluntown, Waterford.
The disease has also been detected in horses in Colchester, Columbia, Montville, Salem, Sterling and Voluntown, and pheasants or partridges in North Stonington.
Health officials said while chillier temperatures are helping to reduce the threat of mosquito bites, there is still a risk.
Many towns and cities have rescheduled or canceled outdoor events after dark amid the EEE threat. Public health officials will be providing an update Tuesday on whether they can move outdoor activites back to their regularly scheduled times.
For now, residents are advised to limit outdoor activities between dusk and dawn, when mosquitoes are most active. If you have to be outside, public health officials advise covering as much skin as possible with long sleeves and pants, and wearing insect repellent.
