About JIA

Some facts you should know about JIA as a parent or caregiver:

• JIA's cause is unknown, but it has been linked to genetic and environmental factors.
• JIA affects each child differently-—with symptoms ranging from a mild short-term condition causing stiffness and some inflammation to a severe disease that causes serious permanent joint and tissue damage.
• Your child may experience other symptoms besides joint pain or swelling.
• These are the types of JIA:
  • Oligoarthritis: Involves fewer than five joints
  • Polyarticular arthritis: Involves five or more joints
  • Systemic arthritis: Characterized by fevers, rash, and organ inflammation, plus arthritis
  • Enthesitis-related arthritis: Involves the spine, hips, and points of bone to tendon attachment (entheses)
  • Psoriatic arthritis: Includes children with arthritis who also have a psoriasis rash
