NY Declares EEE “Imminent Threat” After Ulster County Resident Dies from Rare Mosquito-Borne Virus

An Ulster County resident who was recently diagnosed with Eastern equine encephalitis (EEE) has died, Governor Kathy Hochul announced on Monday. This marks the first case of EEE in New York since 2015, and the state’s Department of Health is urging residents to take precautions to avoid mosquito bites, which transmit the virus.

In response to the death, State Health Commissioner Dr. James McDonald declared EEE an “imminent threat to public health,” enabling local health departments to access additional state resources. These include mosquito spraying and other preventive measures to control the spread of the disease.

“I extend my sincere condolences to the patient’s family and loved ones. This is the first human case of EEE in New York since 2015, and the Ulster County Health Department is working closely with New York State and other partners to monitor the situation and keep the public informed of any additional cases. I urge Ulster County residents to take all precautions to avoid mosquito bites, including by using repellent, wearing long sleeves and long pants, and avoiding outdoor activity at dawn and dusk,” said Ulster County
County Executive Jen Metzger.

Eastern equine encephalitis is a rare but serious viral infection that causes inflammation of the brain. The Department of Health is advising New Yorkers to limit outdoor activities during peak mosquito hours and to use insect repellent to minimize the risk of infection.

Governor Hochul’s announcement underscores the state’s commitment to curbing the spread of mosquito-borne illnesses. The last known case of EEE in the state occurred nearly a decade ago, but the recent resurgence is raising concerns about the threat mosquitoes pose during warmer months.
