Aug. 28, 2019 — Medical officials are warning residents about the rare but deadly eastern equine encephalitis virus, or EEE, which claimed the life of a Massachusetts mother late last week.
“This year, it seems to be much more severe than in past years,” says Brian Chow, MD, an infectious disease doctor at Tufts Medical Center. “It is a concern. We encourage anyone who falls ill to talk to their doctor and come in for medical care.”
Laurie Sylvia of Fairhaven, MA, died while being treated for the infection at Tufts Medical Center on Sunday. She is the fourth case of EEE in Massachusetts this year and the first fatality, The Boston Globe says.
“Today I had to say goodbye to my best friend,” her daughter, Jen Sylvia, wrote in a Facebook post. “My mum was my favorite person in the world. She brought light and joy to everyone she came across.”
In a statement last week, Massachusetts Public Health Commissioner Monica Bharel said, “We are seeing the most intense level of EEE activity that we have seen in several years.”
The virus has also been confirmed in a 14-year old Michigan girl who is fighting for her life, and it is suspected in three others in that state. The mother of Savanah DeHart said her daughter was on a ventilator and could not speak, according to news reports.
Mosquitoes near the Cicero Swamp in New York also tested positive for the virus, along with several chickens in Florida late last month.
Most EEE cases happen east of the Mississippi River between July and September, Chow says.
“It tends to happen in places where mosquitoes like to live, usually in places with still, fresh water,” he says.
People infected with a mild form of the virus usually get flu-like symptoms or may even have no symptoms. For people who are more seriously infected, signs and symptoms include fever, headache, crankiness, restlessness, drowsiness, anorexia, vomiting, diarrhea, convulsions, and coma, according to the CDC.
