The immune reaction that causes reactive arthritis can also affect other organs, notably the eyes. Eye inflammation is an associated symptom along with inflammation of the skin, mouth, and other organs. Reactive arthritis is more frequent in men and in people 20-40 years of age.

Causes of reactive arthritis

An infection on the genital, urinary, or gastrointestinal systems by bacteria such as Chlamydia trachomatis, Shigella, Salmonella, or Campylobacter is most often the cause of reactive arthritis. Medical researchers believe the arthritis arises due to an activation of the immune system to the infection.
