Causes

By Mayo Clinic staff

Reactive arthritis develops in reaction to an infection in another part of your body, often in your intestines, genitals or urinary tract. You may not be aware of the triggering infection because it may cause only mild symptoms or none at all.

Numerous bacteria can cause reactive arthritis. The most common ones include:

  • Chlamydia
  • Salmonella
  • Shigella
  • Yersinia
  • Campylobacter

Reactive arthritis isn't contagious. However, the bacteria that cause it can pass from person to person, such as during sexual contact and food preparation. But only a few of the people who are exposed to these bacteria develop reactive arthritis.
