Massachusetts health officials reported a second confirmed case of the eastern equine encephalitis virus in the state, along with a second case in a horse. The human case involves a woman in her 30s who, along with the horse, was exposed in Plymouth County before aerial spraying occurred on Tuesday. This announcement follows the recent death of a New Hampshire resident from the same virus, marking the first case in a decade for New Hampshire.
Eastern equine encephalitis is a rare yet serious disease that can be transmitted through the bite of an infected mosquito and can be fatal. The first case in Massachusetts this year was a male in his 80s from southern Worcester County. Public health officials emphasize the importance of preventing mosquito bites to reduce the risk of infection, particularly as there is no vaccine or specific treatment available for the virus.
Authorities warn that approximately one-third of those who develop encephalitis from the virus may die, with survivors potentially experiencing lifelong disabilities. This year, 76 mosquito samples in Massachusetts have tested positive for EEE, prompting some towns to advise residents to avoid outdoor activities at night due to concerns over the virus.
In 2019, there were six deaths among 12 confirmed EEE cases in Massachusetts, with the outbreak carrying over into the following year with five more cases and an additional death. In 2014, two out of the three individuals infected in New Hampshire succumbed to the virus. Massachusetts Public Health Commissioner, Robbie Goldstein, stresses the importance of taking precautions against mosquito bites to mitigate the risk of EEE, despite aerial spraying efforts to control the spread of the virus.
