COLCHESTER, CT (WFSB) -- Cities and towns across the state have been altering events and activities due to the threat of Eastern Equine Encephalitis, or EEE.
Colchester is postponing a fireworks display that was set to be held during its annual 57 Fest on Saturday.
In a post on Facebook, Colchester Parks & Recreation said due to the increased risk of EEE in the area “we are taking a conservative approach to protecting the well-being of the Colchester community. Mosquitoes are most active during the hour before dusk, so we have decided to postpone the fireworks to a later date.”
On Monday, the Dept. of Public Health announced the first human case of EEE in the state after an adult from East Lyme tested positive.
While the person is from East Lyme, it is unclear at this time where EEE was contracted.
East Lyme, Norwich, and New London also announced outdoor community-run activities would end by dusk going forward while the threat of EEE exists.
The Colchester festival will still go on, but the fireworks will be postponed to a later date.
EEE has not been detected in Colchester, but the town is simply taking precautions.
However, EEE has been detected in 12 towns already this year.
Peak times for exposure are at dusk and dawn.
EEE is still a mysterious deadly virus, and doctors said some people infected may not have any symptoms, but others can die if the virus spreads to the brain. Doctors say that can happen in 4 or 5 percent of cases.
"Some people are infected and have no symptoms. Other patients who are infected will have a viral like illness, fevers, chills, bones and joints may ache and they’ll feel tired," said Dr. Virginia Bieluch, chief of Infectious Diseases at the Hospital of Central Connecticut.
Doctors said if the virus spreads to the brain, a third of those patients will die.
Those who survive can have serious brain complications for the rest of their lives.
Since there’s no treatment or vaccination for EEE, the best prevention is avoiding the mosquitoes.
While EEE can affect anyone, doctors say the most at-risk age group are those under 15 and those older than 50.
