The New Hampshire Department of Health and Human Services revealed that the person who died of EEE was an adult, and was hospitalized due to severe central nervous system disease before they passed away from their illness, according to a [press release](https://www.dhhs.nh.gov/news-and-media/nh-dhhs-identifies-person-infected-eastern-equine-encephalitis-virus-new-hampshire). The man was then identified by his family as 41-year-old Steven Perry. The family told [WBZ](https://www.cbsnews.com/boston/news/hampstead-new-hampshire-eee-death/) that Perry did not have any underlying conditions. This is the first New Hampshire resident to die of EEE since 2014, and the first infection in the state since that year. In 2014, DHHS identified three human infections, including two fatalities. “We believe there is an elevated risk for EEEV (the virus that causes EEE) infections this year in New England given the positive mosquito samples identified,” said New Hampshire State Epidemiologist Dr. Benjamin Chan. “The risk will continue into the fall until there is a hard frost that kills the mosquitos. Everybody should take steps to prevent mosquito bites when they are outdoors.” The press release also shared that EEE has been detected in one horse and seven mosquito batches in New Hampshire so far this summer, and it pointed to the multiple recordings of EEE in its neighboring states of Vermont and Massachusetts. [Per the Center for Disease Control (CDC),](https://www.cdc.gov/eastern-equine-encephalitis/about/index.html) EEE is incredibly rare, but it is very serious. There are typically only a handful of human cases of EEEeastern equine encephalitis in the U.S. each year —the average being 11 cases reported annually, according to the CDC. Still, the CDC cites the mortality rate for EEE as 30%, and those who survive often experience severe neurological harm. Symptoms can include fever, headache, vomiting, diarrhea, seizures, behavioral changes, and drowsiness. According to the[ Massachusetts DPH](https://www.mass.gov/info-details/eee-eastern-equine-encephalitis), inflammation and swelling of the brain, called encephalitis, is the most dangerous and frequent serious complication of EEE. There is currently no vaccine for EEE, but the CDC recommends clinical monitoring and pain management by medical health professionals in order to relieve symptoms. Humans and some mammals are what’s known as “dead-end hosts,” meaning they do not spread the virus, even though they get sick, to mosquitoes that bite them. According to the [Massachusetts Department of Public Health](https://www.mass.gov/info-details/massachusetts-arbovirus-update#eee-and-wnv-risk-level-by-city/town-), four towns in Massachusetts have raised the EEE risk level to “critical” andsix towns have also raised their EEE risk levels to “high.” **Read more**:[_What to Know About the Rare But Deadly Mosquito-Borne Virus Concerning U.S. Towns_](https://time.com/7014674/rare-but-deadly-mosquito-eastern-equine-encephalitis-virus-us-towns/) The New Hampshire DHHS provided some advice to constituents to prevent mosquito bites, especially as EEE crops up. This includes using “effective mosquito repellents,” wearing long sleeves and pants when outside. especially during peak mosquito hours in the early morning and evening— or, avoiding outdoor activities during those hours altogether. They also recommended draining standing water around the home and placing or repairing bug screens. ## Transcript [00:00] S neck wine andcephalts, [00:01] short term is triple is a virus infection [00:07] carried by mosquitoes that can cause very rarely causes disease in humans. [00:14] And when it does cause a infection is very, very severe. [00:19] Although it's a very rare infection, [00:21] we have no treatment for it to do this. [00:24] And once someone gets it, [00:26] it just all we can do is provide supportive care, [00:29] and it can kill people. [00:31] Well, this is a virus which is present in the environment in Southern New England. [00:39] So there are cases in Massachusetts, [00:42] cases in Rhode Island, cases in Connecticut. [00:45] Tends to be areas that where there were a certain kind of mosquito lives. [00:50] That tends to be areas that used to be [00:53] swamp land that's been converted and less swampy now, [00:56] but the mosquitos still find good habitat. [00:59] We don't see Tripoli activity every year in Massachusetts. [01:03] It tends to occur in outbreak cycles. [01:05] Our last outbreak cycle is 2019 through 2020. [01:10] And what we have seen over sort of the last, you know, ten, [01:16] 12 years is that we're starting to see [01:20] increases of triple activity outside of the historic hot spot. [01:26] And we're concerned that that's due to a couple of factors, [01:30] including some of the climate change likely climate change effects, [01:36] like a warming temperature, [01:38] changes in migratory bird patterns, [01:41] and changes in precipitation activity as well. [01:45] So we work very hard to make sure people are aware of where and when Tripoli is [01:51] happening and make sure they [01:53] understand the steps that they can take to help protect themselves, [01:57] including using a mosquito repellent anytime they're outside. [02:01] When it's not super hot, [02:03] you can use clothing to reduce exposed skin. [02:06] And then in areas where Triple risk is very elevated. [02:11] So not the entire state, [02:13] but parts of the state, [02:14] we make a recommendation that people avoid [02:17] outdoor activity between the hours of dusk and dawn. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/7015554/eee-death-mosquito-new-hampshire/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/7015554/eee-death-mosquito-new-hampshire/"},"headline":"Rare Mosquito-Borne Disease Causes First Death in New Hampshire","datePublished":"2024-08-28T16:55:43.000Z","dateModified":"2026-10-19T07:46:22.180Z","description":"A New Hampshire resident has died of the rare but serious Eastern Equine Encephalitis virus (EEE), health officials said Tuesday.","url":"https://time.com/7015554/eee-death-mosquito-new-hampshire/","keywords":["Disease","News Desk"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltc6b79c12aa782fb5/698a5a54b21a9c0bdb50a656/GettyImages-51149086.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Rebecca Schneid","jobTitle":"Reporter","url":"https://time.com/author/rebecca-schneid/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltc6b79c12aa782fb5/698a5a54b21a9c0bdb50a656/GettyImages-51149086.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Arizona Officials Battle West Nile Virus","caption":"Arizona Officials Battle West Nile Virus","creditText":"Jeff Toppings—2004 Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/tag/disease/","name":"Disease"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/7015554/eee-death-mosquito-new-hampshire/","name":"Rare Mosquito-Borne Disease Causes First Death in New Hampshire"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"What to Know About the Rare But Deadly Mosquito-Borne Virus Concerning U.S. Towns","description":"A coastal town in Massachusetts is shutting its parks, playgrounds, and fields from dusk to dawn due to concerns about the mosquito-borne virus Eastern equine encephalitis (EEE).","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/ekIK9jYV/poster.jpg?width=720","uploadDate":"2024-08-27T14:42:11.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/ekIK9jYV.m3u8","embedUrl":"https://time.com/7015554/eee-death-mosquito-new-hampshire/","duration":"PT2M21S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/7015554/eee-death-mosquito-new-hampshire/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
