JIA was once called juvenile rheumatoid arthritis (JRA), but it has been renamed because it is not a childhood version of an adult disease. The term "juvenile arthritis" is used to describe all joint conditions that affect children and teens, including JIA.
What are the three types of JIA?
The three main types are: Oligo joint JIA (arthritis of 4 joints or less) Polyarticular JIA (arthritis of 5 joints or more) Whole body JIA (arthritis and fever, rash, large lymph node)
When will JIA become Ra?
Over the years, the definition of juvenile idiopathic arthritis (JIA) has expanded. It currently includes all types of arthritis that begin before the age of 16 and last for more than 6 weeks.
