Juvenile Idiopathic Arthritis (JIA)

Children with juvenile idiopathic arthritis (JIA) have swelling or pain ranging from very mild limited joint involvement to severe systemic disease associated with high fever, rash and lymph node enlargement. There are several types of JIA. The three major subtypes are:

  • Oligoarticular JIA
  • Polyarticular JIA
  • Systemic JIA

In the past, these diseases were called “juvenile rheumatoid arthritis,” or “JRA,” "juvenile arthritis" or "juvenile chronic arthritis."  

Juvenile idiopathic arthritis is the most common type of arthritis in children. It is a chronic disease. This means it will probably last a long time. About one in 1,000 children have JIA. The number of new cases per year is estimated at nine per 100,000 people. These numbers tell us that about 40-50 children in the Cincinnati area will be diagnosed with JIA each year.
