What is juvenile idiopathic arthritis?

Juvenile idiopathic arthritis (JIA) is the name given to a number of types of arthritis that occur in children.

The name comes from:
Juvenile: referring to children under the age of sixteen years.
Idiopathic: meaning it has no known cause.
Arthritis: conditions that cause joint inflammation and pain.

What are the main symptoms of JIA?

• joint pain, swelling, tenderness, stiffness, redness and warmth
• fatigue (tiredness and lack of energy), fevers, loss of appetite or weight, and generally feeling unwell
• skin rashes
• inflammation of the eyes (uveitis) and other organs of the body in some forms of the disease.

Information for extended family

Information for kids and young people.

Understanding JIA and how it affects someone can be difficult for people of all ages. We’ve made these animations to help young people understand more about JIA, whether that be friends, family or classmates. These videos are designed to help young people who don’t have JIA understand more about the condition and how it may affect someone.

Information for teachers and school staff

School staff play an important part in helping children and young people living with JIA manage their condition during the school day. This animation is designed to help teachers and other school staff understand more about the condition, how it may affect activities and tasks during the school day, and things that may help.
