Juvenile arthritis (JIA) is generally considered an uncommon group of conditions in children, but “rare” does not mean “low impact.” Even though it is not frequent, JIA can significantly affect growth and development, school participation, physical activity, and quality of life. A major challenge in less common diseases is delayed recognition—limping or morning stiffness may be dismissed as temporary. That is why awareness among families and primary care clinicians is important. With early diagnosis and structured monitoring, many children achieve good control. Some subtypes also carry silent yet important risks such as uveitis. The “rare” label should not reduce urgency; it should strengthen the case for planned follow-up and treat-to-target discipline.
