Answer

Genitourinary infections, especially those due to Chlamydia trachomatis, are the second most common cause of reactive arthritis. The arthritis of Lyme disease usually results from immunologic mechanisms, with a minority of cases due to direct invasion by an organism.

A reactive/postexposure process may occur months after the gastrointestinal or genitourinary process has resolved.
