“We encourage residents of Southeast Connecticut to take simple steps such as wearing mosquito repellent and covering bare skin, especially at dusk and dawn when mosquitoes are most active,” the said. State Public Health Commissioner, Manisha Juthani. “While the detection of the EEE virus is concerning, it’s important to remember that we don’t expect to see a lot of mosquito activity in October.”
