New Hampshire resident dies after testing positive for mosquito-borne encephalitis virus
New Hampshire health authorities say a person infected with the mosquito-borne eastern equine encephalitis virus has died
A New Hampshire resident infected with the mosquito-borne eastern equine encephalitis virus has died, state health authorities said.
The Hampstead resident's infection was the first in the state in a decade, the New Hampshire Department of Health and Human Services said Tuesday. The resident, whom the department only identified as an adult, had been hospitalized due to severe central nervous system symptoms, the department said.
About a third of people who develop encephalitis from the virus die from the infection, and survivors can suffer lifelong mental and physical disabilities. There is no vaccine or antiviral treatment available for infections, which can cause flu-like symptoms and lead to severe neurological disease along with inflammation of the brain and membranes around the spinal cord.
“When it does cause an infection, it is very, very severe. Although it’s a very rare infection, we have no treatment for it,” said Dr. Richard Ellison, immunologist and infectious disease specialist at University of Massachusetts Memorial Medical Center. “Once someone gets it, it’s just — all we can do is provide supportive care, and it can kill people.”
