Two new human cases of the mosquito-borne Eastern Equine Encephalitis virus have been confirmed in Massachusetts, the Massachusetts Department of Health announced Friday.
The newest cases were found in a woman in her 60s from eastern Worcester County and a girl under 18 from southwestern Middlesex County.
Risk levels in four communities have been raised to critical as a result of the newly confirmed cases. The communities newly listed as at critical risk are Framingham, Marlborough, Northborough, and Sudbury.
Risk levels in six communities — Berlin, Boylston, Hudson, Maynard, Stow, and Wayland — have been raised to high.
