ALBANY, New York – The first confirmed case of Eastern equine encephalitis (EEE) in nearly a decade in New York has resulted in the death of a resident, leading health authorities to declare an imminent threat to public health. The individual from Ulster County, diagnosed with EEE on September 20, tragically passed away, as announced by Governor Kathy Hochul on Monday.
This recent case of EEE is the first in New York since 2015, prompting an investigation by the county’s health department, according to statements released by state officials. EEE is a rare mosquito-borne illness that can be serious and potentially deadly.
Following the diagnosis of the Ulster County patient who succumbed to EEE last week, State Health Commissioner Dr. James McDonald issued a declaration of imminent threat to public health. This declaration enables the mobilization of state resources to aid in EEE prevention efforts, including ongoing mosquito spraying, until November 30.
In response to the EEE case in Ulster County, multiple state agencies such as the Department of Environmental Conservation and the Parks Department have taken action to enhance access to bug repellent in public sites. Governor Hochul expressed her priority of keeping New Yorkers safe and extended her condolences to the family of the deceased patient.
As EEE poses a significant risk to public health, visitors to state parks and other public sites will see increased signage regarding EEE risks, along with more mosquito spray available. Park hours and camping availability may also be adjusted during periods of heightened mosquito activity.
Eastern equine encephalitis, spread by infected mosquitoes, is a rare but severe disease that can result in death for about 30% of cases. Health experts warn that symptoms of severe cases include headache, high fever, chills, and vomiting. The disease has no available human vaccine and is particularly dangerous this year due to the increased presence of infected mosquitoes across New York State.
Dr. McDonald emphasized the seriousness of EEE this year as the mosquitoes have been detected in 15 counties so far, compared to the usual two to three counties annually. The threat of EEE mosquitoes may persist until freezing temperatures occur, potentially lingering into the winter months.
Apart from New York, EEE cases have been reported across the U.S. this year, with fatalities recorded in New Hampshire as well. Additionally, the virus has been identified in several horses in various New York counties. While there have been no human cases reported in Suffolk County, health officials urge residents to remain vigilant and take precautions against mosquito bites to prevent further spread of EEE.
