BURLINGTON (AP) - The Vermont Department of Health says the Eastern Equine Encephalitis virus brought by mosquitoes has been detected in a batch of the insects collected in the town of Grand Isle.

The department says the mosquitoes were trapped on June 17, making this the earliest detection of the virus in the Northeast.

This is also the first time EEE virus has been detected in Grand Isle County. Two horses from Franklin County and a batch of mosquitoes in Milton tested positive for the virus in 2013.

Mosquitoes carrying the West Nile virus also have been found in Vermont in the past.
