Fatality of New Hampshire resident due to mosquito-transmitted encephalitis virus infection

A New Hampshire resident has recently passed away after contracting the eastern equine encephalitis virus transmitted by mosquitoes, as confirmed by state health officials. This infection in a resident of Hampstead marks the first case in the state in ten years, according to the New Hampshire Department of Health and Human Services. The individual, identified by the department only as an adult, was hospitalized for severe central nervous system symptoms related to the virus.

Eastern equine encephalitis is a serious illness that can lead to encephalitis, a swelling of the brain, causing flu-like symptoms and potentially resulting in severe neurological issues and inflammation around the brain and spinal cord. Approximately a third of individuals who develop encephalitis due to this virus do not survive and those who do may face long-term mental and physical impairments. Sadly, there is no vaccine or specific antiviral treatment available for this infection, making it particularly challenging to manage once contracted.

Dr. Richard Ellison, an immunologist and infectious disease specialist at the University of Massachusetts Memorial Medical Center, emphasized the severe nature of the infection, highlighting the lack of effective treatment options available. The virus has been detected in a horse, as well as in several mosquito populations in New Hampshire this summer. Cases of infected individuals in Massachusetts and Vermont have also been reported, indicating a broader regional concern.

Given the heightened risk of eastern equine encephalitis infections this year, health authorities are urging residents to take precautions to avoid mosquito bites. This includes using insect repellent, wearing long-sleeved clothing, and staying indoors during peak mosquito activity times, such as early morning and evening. Additionally, eliminating sources of standing water, where mosquitoes breed, is crucial in preventing the spread of the virus.

In response to the increased threat of mosquito-borne illnesses, some Massachusetts towns have recommended avoiding outdoor activities at night this summer. Authorities in Massachusetts have initiated spraying programs to mitigate the mosquito population and reduce the risk of infections in communities. Efforts to prevent mosquito bites and control mosquito populations are crucial in protecting public health as the risk of eastern equine encephalitis and other mosquito-borne diseases persists in the region until the arrival of a hard frost.
