What is the difference between stills disease and reactive arthritis?

Very different: Reactive arthritis (previously called reiter's disease) is a self-limited arthritis that develops as an autoimmune response to an infection (some diarrheal infections, some sexually transmitted infections, some respiratory infections).Very painful swollen joints, sometimes with eye inflammation (uveitis), and urethral inflammation.Still's disease is systemic jia when in kids and is a chronic disease.

Maybe none!: If we do not know the infectious trigger, jia or still's in adults or children are therefore not caslled reactive arthritis. My personal belief is that they are all reactive arthritities. Children do not develop rheumatoid arthritis, unless usally females after puberty.
