Three Probable Tularemia Cases Spotlight Tick-Borne Rabbit Fever on Long Island

Suffolk County health officials report three probable tularemia cases, a rare tick- or animal contact–transmitted infection also known as rabbit fever caused by F. tularensis. It is not spread person-to-person and can be contracted via tick or fly bites, direct contact with sick animals, contaminated water, or undercooked game. Symptoms include high fever, swollen lymph nodes, body aches, and a painful sore, typically appearing 3–5 days after exposure (up to 21 days). Treatment is with antibiotics; a vaccine exists only for lab workers and is not generally available. Prevention includes avoiding ticks with protective clothing and checks, wearing gloves when skinning game, and cooking meat thoroughly. Suffolk has seen several recent cases, with 2025 data not yet available, and officials warn of a potentially tougher tick season after a mild winter.
