Massachusetts Responds to Rare Mosquito Virus with Increased Precautions

A rare but deadly mosquito-borne disease has led one Massachusetts town to close its parks and fields each evening. Four other towns are advising residents to stay indoors at night due to concerns about eastern equine encephalitis (EEE). State health officials recently reported the first human case in Massachusetts since 2020, involving a man in his 80s.

The town of Plymouth, located about 40 miles southeast of Boston, announced on Friday that it would close public outdoor recreation facilities from dusk until dawn after a horse in the town was infected with EEE. Meanwhile, state health officials have warned that Douglas, Oxford, Sutton, and Webster are at "critical risk" after a man from Oxford contracted the virus.

Precautionary Measures

Residents in these towns are urged to avoid peak mosquito biting times by finishing outdoor activities by 6 p.m. until September 30 and then by 5 p.m. thereafter until the first hard frost. Additionally, people across Massachusetts are advised to use mosquito repellents when outdoors and to eliminate any standing water around their homes.

Jennifer Callahan, Oxford's town manager, shared in a memo that the family of the man who contracted the virus in mid-August had contacted 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.

Impact on Infected Individuals

Callahan mentioned that the infected individual had often told his family he never got bitten by mosquitoes. However, just before showing symptoms, he reported being bitten. The man remains hospitalized and is "courageously battling" the virus. The family urges everyone to take public health advice seriously and protect themselves.

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

Severity of EEE

The US Centres for Disease Control and Prevention (CDC) states that although EEE is rare, it is very serious, with about 30 per cent of infected individuals dying. Symptoms include fever, headache, vomiting, diarrhea, and seizures. Survivors often face permanent disabilities, with few making a full recovery.

EEE is prevalent in birds, and while humans and some other mammals can contract it, they do not spread the disease. The CDC notes that only a few cases of EEE are reported annually in the US, primarily in eastern and Gulf Coast states.

There are no vaccines or treatments available for EEE. Health officials continue to stress the importance of preventive measures to reduce the risk of infection.

The situation remains critical as communities work together to mitigate the spread of this dangerous disease.
