State health officials are confirming a fourth case of Eastern equine encephalitis in Massachusetts.
State Public Health officials said late yesterday the Marshfield man in his 60s is hospitalized.
Marshfield Public Health officials say in a statement, “effective immediately, the Marshfield Board of Health orders the restriction of all public outdoor group activities (sports, recreational, and gatherings) between the hours of dusk and dawn, starting at 6:15 p.m. until further notice (first frost).”
Because of the new cases, the DPH raised the mosquito threat level for EEE to “high” in Duxbury, Marshfield, Norwell and Plymouth, and urged cancellation of outdoor evening activities.
Officials also announced a 14th case of West Nile virus, in a Hampden County man in his 50s who has been discharged from a hospital.
Both illnesses area carried by mosquitoes.
A Worcester County man in his 70s died of EEE last month.
The West Nile threat was raised to “high” in Agawam, Easthampton, Hadley, Northampton, Southampton, and Westfield.
