Massachusetts Woman Dead From Deadly, Rare Mosquito-Born Virus

A Massachusetts woman died Sunday after contracting a rare and deadly mosquito virus. Laurie Sylvia, 59, of Bristol County, Massachusetts, reportedly fell ill on Aug. 19 and died after seeking treatment at a hospital.

Medical examiners' autopsy revealed that the cause of death was from the rare virus, Eastern Equine Encephalitis, or EEE. The most dangerous symptom of the virus is brain inflammation that is manifested in seizures, fever, and possibly a coma, according to the CDC.

Laboratory testing confirmed that Sylvia was the fourth cases in the state, according to the Massachusetts Department of Public Health. The department on Friday confirmed the third human EEE case in a Massachusetts was a man over the age of 60.

Those infected typically start showing symptoms four to 10 days after being bitten by an infected mosquito. One-third of those infected with EEE die, while any survivors may suffer from mild to severe brain damage.

It is spread by mosquitos already infected with the virus and is extremely rare, with only five to 10 cases reported in the U.S. every year. However, EEE has appeared to be especially active in Massachusetts this year, with Sylvia being the fourth confirmed case in the state for 2019.

The Fairhaven Health Department has worked with the Fairhaven Fire Department to warn residents about the virus and how to prevent it. State authorities have sprayed communities to slow the mosquito population.

“Today I had to say goodbye to my best friend,” Sylvia's daughter, Jen Sylvia, wrote on Facebook. “My mum was my favorite person in the world. She brought light and joy to everyone she came across. She would be there for anyone at any time. Her smile was contagious. Her jokes were priceless. She was the life of the party. She knew how to have fun and taught me how important it was to love with all you’ve got and live life to the fullest. She was the best Mimi anyone could ask for. I am grateful for the memories my children will carry.”
