Massachusetts Towns Caution People After Outbreak of 'Rare' Deadly Mosquito Virus

Washington: A rare but deadly disease spread by mosquitoes has one town in Massachusetts closing its parks and fields each evening. Four other towns are urging people to avoid going outdoors at night.

First Human Case Widespread Concern

They're concerned about eastern equine encephalitis. State health officials announced last week a man in his 80s had caught the disease, the first human case found in Massachusetts since 2020.

The town of Plymouth, about 40 miles (64 kilometers) southeast of Boston, announced Friday that it's closing public outdoor recreation facilities from dusk until dawn each day after a horse in the town was infected with the disease.

Cluster of Towns at "Critical Risk" Following Second Infection

Meanwhile, state health officials warned that a cluster of four towns south of Worcester Douglas, Oxford, Sutton and Webster are at “critical risk” after a man from Oxford caught the virus.

State and local health officials urged people in those towns to avoid the peak mosquito biting times by finishing outdoor activities by 6 p.m. until September 30 and then by 5 p.m. after that, until the first hard frost.

Public Health Advisory

They also recommend that people across Massachusetts use mosquito repellents when outdoors and drain any standing water around their homes.

Family of Infected Man Issues a Serious Warning

Jennifer Callahan, Oxford's town manager, wrote in a memo that the family of the man who caught the virus in mid-August had reached out to her office.

“They want people to be aware this is an extremely serious disease with terrible physical and emotional consequences, regardless if the person manages to live,” Callahan wrote.

She said the infected person had often recounted to his family how he never got bitten by mosquitoes. But just before he became symptomatic, he told them he had been bitten. She said the man remains hospitalized and is “courageously battling” the virus.

Callahan said the family is urging people to take the public health advice seriously and to do their utmost to protect themselves.

EEE Presence Confirmed in Mosquitoes Across the State

The presence of the virus in Massachusetts this year was confirmed last month in a mosquito sample, and has been found in other mosquitoes across the state since then. In a 2019 outbreak, there were six deaths among 12 confirmed cases in Massachusetts. The outbreak continued the following year with five more cases and another death.

No Vaccines or Treatments Available for EEE

There are no vaccines or treatments for EEE. The US Centres for Disease Control and Prevention says that although rare, EEE is very serious and about 30 per cent of people who become infected die. Symptoms include fever, headache, vomiting, diarrhea and seizures.

Long-Term Impact on Survivors Can Be Severe

People who survive are often permanently disabled, and few completely recover, Massachusetts authorities say. The disease is prevalent in birds, and although humans and some other mammals can catch EEE, they don't spread the disease.

The CDC says only a few cases of EEE are reported in the US each year, with most infections found in the eastern and Gulf Coast states.
