Etymology: Echinococcosis is built from two pieces that each carry their own history. The first, "Echinococcus," is the genus name for the tapeworms that cause the infection. It comes from Greek "echinos," meaning "hedgehog" or "sea urchin," with "kokkos," meaning "berry" or "grain." The name refers to the hooked, spiny structure on the tapeworm's head (the scolex), which looks like a prickly seed. The second part, "-osis," is a suffix from Greek used in medicine to denote a diseased or abnormal condition, so the whole word names the disease caused by Echinococcus infection.
