New York Resident Dies from Rare Mosquito-Borne EEE Virus

New York state officials confirmed the death of a resident from Ulster County due to Eastern equine encephalitis (EEE), marking the state’s first case of the virus in nearly a decade. The case was diagnosed on September 20th by the state Department of Health, and a declaration of an imminent public health threat was issued shortly after. The declaration allows for expanded efforts to combat the mosquito-borne disease, including ongoing mosquito spraying through November 30, 2024.

EEE is a rare but severe illness transmitted by infected mosquitoes. It can lead to encephalitis, or brain inflammation, and has a fatality rate of approximately 30% in severe cases. The New York Department of Health noted that the virus has been spreading more aggressively this year, with mosquitoes carrying the virus found in 15 counties across the state. State Health Commissioner Dr. James McDonald emphasized the seriousness of the situation, stating, “Mosquitoes, once a nuisance, are now a threat.”

The Ulster County resident’s death follows a nationwide increase in EEE cases, with at least 11 reported in the United States so far this year. Other states, including Massachusetts, New Hampshire, and New Jersey, have also reported cases. The Centers for Disease Control and Prevention (CDC) warns that while many infected individuals show no symptoms, severe cases can result in fever, headache, vomiting, and neurological complications such as seizures and paralysis.

Governor Kathy Hochul expressed her condolences to the victim’s family, stating that “keeping New Yorkers safe is my top priority.”  She said, “Following the first confirmed human case of EEE, my administration took statewide action to help protect communities – and with today’s declaration we’re making more State resources available to local departments to support their public health response.” In response to the growing threat, the state has initiated public awareness campaigns, encouraging residents to use insect repellents and eliminate standing water where mosquitoes breed. Park hours may also be curtailed to reduce the risk of exposure.

Officials urge residents to remain vigilant as the mosquito population may persist until freezing temperatures arrive. Preventive measures, such as wearing long sleeves and using repellents, are critical as there is no vaccine available for EEE. The state continues to monitor the situation and take measures to protect public health.
