Juvenile Arthritis (or better known as Juvenile Idiopathic Arthritis-JIA) is the most common chronic condition affecting the joints with pain and/or swelling. Sometimes in young children the developmental skills are lost, or in the teenager or young adult sports participation is not possible. With about one in 1000 children affected, it makes it slightly more common than diabetes in children. There are different types of JIA depending on how many joints affected, or if there are any other symptoms such as fever or rash. For example Systemic Arthritis (previously known as Still’s Disease) commonly presnets with fevers and rashes in an unwell child.
