In brief: Autoimmune
Jra (also called jia) for juvenille idiopathic arthritis is a disease of unknown etiology.
There are many theories for why it happens, many believe there is a virus responsible. The damage to the joints, pain and stiffness is due to an inappropriate immune response which results in the immune system attacking tissues of the host (patient). Rheumatologists can provide appropriate DX and rx.

In brief: We don't really know
There seems to be a genetic predisposition to developing jra.
It is thought that there may be environmental factors that trigger ones immune system to inappropriately attack one body tissues. (autoimmune) for example exposure to smoking has been implicated. Considerable research is being conducted on finding the exact triggers and autoimmune pathways.
