The “triple e” alert, for eastern equine encephalitis, has been raised to “high” in five south shore communities, including Hanover, Hanson, Rockland, Weymouth and Whitman.
Some towns, such as Whitman, have sent “code red messages” via the Plymouth County Sheriff’s Department to their residents.
Whitman’s message says in part, “a recent case of EEE involved a woman who had spent time in both Weymouth and Whitman”
Whitman is curtailing outdoor activities from dusk to dawn.
The Hanson board of health is also curtailing all outdoor activities from 6:30 pm to 6:00 am.
Several other towns have had their risk level raised as well to “moderate”. Those towns include Braintree, Holbrook, Abington, East Bridgewater, Hingham, Norwell, Pembroke and the city of Brockton.
There has been one confirmed case of EEE this year in a Massachusetts resident.
