Lyme disease is a multisystem tick-borne zoonosis primarily caused by spirochetes of the *Borrelia burgdorferi* sensu lato complex, transmitted through the bite of infected *Ixodes* species ticks If untreated, hematogenous dissemination can involve the nervous system, myocardium, and joints, producing cranial nerve palsies, carditis with conduction blocks, or recurrent oligoarticular arthritis, most notably in the knees
