What is polyarticular course JIA?

Polyarticular JIA is an autoimmune disease. This means that the body’s immune system, which normally attacks germs, mistakenly attacks the joints. This causes inflammation (swelling and irritation) in the joints and other problems. Polyarticular JIA usually starts when kids are 1–3 years old, or 10–14 years old.
