BOSTON -- Mosquitoes from the town of Berkley have tested positive for Eastern equine encephalitis, and samples from several towns tested positive for West Nile virus, the Department of Public Health announced Tuesday.

The mosquito samples were collected from the communities of Boston, Clinton, Foxborough, New Bedford, Newton, Northampton, Norton, Wayland, Westport and Westwood.

In addition to these mosquito samples, West Nile virus has also been found in crows from Barnstable, Edgartown, East Longmeadow, Longmeadow, Norfolk, North Andover and Hatfield, and in blue jays from Barnstable, Carlisle, Hampden, Scituate and Watertown.

"Even though many of us think of Labor Day Weekend as the end of summer, mosquitoes will be around until a hard frost,” said DPH State Epidemiologist Dr. Al DeMaria. “We are still seeing a lot of virus around -- in every part of the state. Kids will soon be involved in after school activities during the time of day when mosquitoes are most active, so we want parents and schools to remind young people to cover up and use bug spray to help prevent mosquito bites.”

While there weren’t any human cases of EEE during 2007, there were 13 cases with 6 deaths from 2004 through 2006. In 2007, there were six human cases of West Nile virus in Massachusetts.

Both EEE and West Nile virus are usually spread to humans through the bite of an infected mosquito. West Nile virus can infect people of all ages, but people over the age of 50 are at higher risk for severe disease. EEE is a generally more serious disease in all ages and can even cause death.
