In a tragic turn of events, a resident of Ulster County, New York, has died after being diagnosed with Eastern Equine Encephalitis (EEE), a rare but deadly mosquito-borne illness. This marks the first confirmed case of EEE in the state in nearly 10 years, prompting Governor Kathy Hochul to declare the disease an imminent public health threat. The news follows an uptick in reported cases across the United States, heightening concerns about the potential for further infections.

What Is Eastern Equine Encephalitis?
Eastern Equine Encephalitis (EEE) is a viral infection transmitted through the bite of an infected mosquito. Although rare, the disease can cause severe neurological complications, including swelling of the brain (encephalitis), and has a mortality rate of approximately 33% in humans. Those who survive are often left with lifelong disabilities, such as cognitive impairments and motor dysfunction.
According to the Centers for Disease Control and Prevention (CDC), EEE is considered endemic in North America, meaning that cases occur regularly but infrequently. Symptoms often begin with fever, headache, and chills but can rapidly escalate to seizures, coma, and death in severe cases. There is currently no vaccine or specific antiviral treatment for the disease, making prevention critical.
The Ulster County Case and Rising Concerns
The victim in New York, whose identity has not been disclosed, was confirmed to have contracted the virus on September 20, 2024. This tragic death marks the second EEE-related fatality in the U.S. this year, following the death of a 41-year-old man in New Hampshire in August.
The Ulster County case stands out not only because it’s the first in the state since 2015 but also due to the rapid spread of the virus in mosquitoes across New York. James McDonald, New York’s Health Commissioner, has expressed heightened concern, noting that EEE-positive mosquitoes were detected in 15 counties, compared to the usual two to three. This includes Suffolk County on Long Island, a region not typically associated with EEE cases.
“EEE is different this year. Mosquitoes, once a nuisance, are now a threat,” McDonald emphasized, urging New Yorkers to take protective measures, such as using insect repellent, wearing long-sleeved clothing, and eliminating standing water near their homes to reduce mosquito breeding grounds.
Government Response to the Crisis
In response to this alarming development, Governor Hochul has implemented a series of measures aimed at curbing the spread of the disease. These include:
- Increased Public Awareness: State parks will display signage warning visitors about the risks of EEE, and mosquito repellent will be made readily available at park offices and visitor centers.
- Consultations with Local Health Departments: Discussions are ongoing about potentially limiting park hours or even closing certain areas during peak mosquito activity periods, such as dusk and dawn.
- Social Media Campaigns: The Department of Environmental Conservation (DEC) and other state agencies will use social media to spread crucial information about how to protect against mosquito bites.
These efforts are intended to minimize the risk of further infections as New York approaches the end of mosquito season, typically marked by the first frost in mid-October.
The Nationwide Picture
EEE is not just a New York problem. So far in 2024, ten human cases have been confirmed across several states, including Massachusetts, New Jersey, Rhode Island, Vermont, and Wisconsin. The CDC has recorded sporadic outbreaks over the years, with the most notable occurring in 2019 when 38 cases and 12 deaths were reported, the largest outbreak in over half a century.
While EEE garners significant attention due to its high fatality rate, other mosquito-borne diseases also pose a serious risk. As of mid-September, the CDC reported 659 cases of West Nile virus across the country. Although less deadly than EEE, West Nile remains a significant health concern.
Who Is at Risk?
Anyone can contract EEE if bitten by an infected mosquito, but certain populations are more vulnerable. Those most at risk include:
- Children under 15 and adults over 50
- People living in areas with large mosquito populations, particularly in rural and forested regions
- Individuals who spend extended periods outdoors, especially during peak mosquito activity hours
In addition to humans, EEE also severely impacts animals, particularly horses. The mortality rate for infected horses can be as high as 90%, and cases have been reported in New York this year, including the deaths of two horses in Ulster County. Even more rare, two emus in Rensselaer County recently died from EEE.
How to Protect Yourself from EEE
Given the absence of a vaccine or treatment, preventing mosquito bites is the best defense against EEE. New Yorkers, especially those in counties where infected mosquitoes have been detected, should take the following precautions:
- Use EPA-registered insect repellents that contain DEET, picaridin, or oil of lemon eucalyptus.
- Wear long-sleeved clothing and pants when outdoors, particularly during dawn and dusk, when mosquitoes are most active.
- Eliminate standing water around your home, such as in flower pots, gutters, and birdbaths, as mosquitoes breed in stagnant water.
- Keep window screens intact to prevent mosquitoes from entering homes.
Conclusion
The death of an Ulster County resident from EEE is a stark reminder of the growing threat posed by mosquito-borne diseases. As cases rise, it’s essential for New Yorkers and residents of other affected states to remain vigilant. The state’s response is comprehensive, but individual efforts to prevent mosquito bites remain a critical part of the battle against this deadly virus. With no known cure, proactive prevention is the only way to protect yourself and your loved ones from this devastating disease.
By taking the necessary precautions, we can minimize the risk of future infections and fatalities as we work together to combat the spread of EEE.
