State officials are confirming the second human case of eastern equine encephalitis. 

Officials say a woman in her 30s in Plymouth County has tested positive for the mosquito-borne illness. 

The state Department of Public Health reported earlier this month that a man in his 80s in Worcester County had contracted the disease, which was the state's first human case since 2020. 

Two horses have also tested positive for Triple-E in the state this summer.
