Juvenile Idiopathic Arthritis is a form of arthritis occurring in kids. This is an autoimmune disease. In this disease, there is infection occurring in the joints of small kids leading to inflammation, pain, redness, or other reactions etc. According to the studies made, here, the white blood cells of the body cannot distinguish between the bacteria or foreign particles and body’s own healthy cells. Due to this, many of the body’s healthy cells and tissues get engulfed through the process of phagocytosis leading to cell death.
