Reactive arthritis, also known as Reiter’s syndrome, is a type of arthritis that occurs as a reaction to an infection somewhere in the body. Most infections that cause the disease originate in the genitourinary tract (the bladder, urethra, penis, or vagina) and are spread through sexual intercourse, a form of the disease called genitourinary Reiter’s syndrome, or urogenital Reiter’s syndrome. Other infections that can cause reactive arthritis include gastrointestinal infections due to eating contaminated food or handling contaminated substances, a form of the disease called gastrointestinal Reiter’s syndrome, or enteric Reiter’s syndrome.

About 75 percent of persons with the tendency to develop this disease have a special gene marker called HLA-B27.
