It may also cause inflammation of the eyes, skin and urinary and genital systems. Causes The exact cause of reactive arthritis is unknown. However, it most often follows an infection, but the joint itself is not infected. Reactive arthritis most often occurs in men between the ages of 20 and 40, although it does sometimes affect women. It may follow an infection in the urethra after unprotected sex. The most common bacteria that cause such infections is called Chlamydia trachomatis. Reactive arthritis can also follow a gastrointestinal infection (such as food poisoning). In up to one half of people thought to have reactive arthritis, there may be no infection. It is possible that such cases are a form of spondyloarthritis.SpondyloarthritisAnkylosing spondylitis (AS) is a chronic form of arthritis.
