Childhood arthritis is called juvenile arthritis or juvenile idiopathic arthritis. It is also referred to as juvenile rheumatoid arthritis (JRA), though that is an older term.
Juvenile arthritis is actually not just one condition.
Many things can cause arthritis in children, including infections (septic arthritis), reactions to infections (reactive arthritis), and other conditions.
There are many different types of juvenile idiopathic arthritis too, including:
Oligoarthritis – only 1 to 4 joints are affected during the first six months
Polyarthritis – can be either rheumatoid factor negative or positive – 5 or more joints are affected during the first six months
Enthesitis-related arthritis – have inflammation where a tendon inserts onto a bone
Undifferentiated arthritis etc.
