Etymology: Leptospirosis is a plain technical compound, built from the genus name "Leptospira" plus the medical suffix "-osis," meaning a diseased condition. The genus name itself is a New Latin coinage from Greek roots: "leptos" meaning thin or slender, and "speira" meaning coil or spiral, a reference to the tightly coiled, thread-like bacteria that cause the infection. The word therefore describes an illness caused by a slender spiral-shaped microbe, and the name records the organism's shape rather than the disease's symptoms. The infection is passed from animals to people through contact with contaminated water, soil, or urine, which is why the disease is classed as zoonotic.
