Reactive arthritis can be triggered by infections in which body systems?

Explanation:
Reactive arthritis is driven by an immune reaction that follows infection at mucosal surfaces. The classic triggers come from the gastrointestinal tract and the genitourinary tract. Infections in these two systems—GI infections like Shigella, Salmonella, Yersinia, Campylobacter and GU infections such as Chlamydia trachomatis—can precede and precipitate the arthritis. Because respiratory infections are not typical triggers for reactive arthritis, they don’t fit as well. So infections in both the GI and GU systems best explain how reactive arthritis is triggered.
