Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a type of pediatric autoimmune disease that commonly affects infants and young children, especially those under the age of five. The exact mechanisms and causes of the disease are still unclear. The primary pathological change is systemic vasculitis, frequently affecting the coronary arteries. The recurrence rate of Kawasaki disease is between 1%-3%, with a few cases experiencing three or even four occurrences. The interval between recurrences ranges from three months to one year, averaging one year and five months. Studies have shown that being younger than three years old at the time of the first episode and having vascular damage are risk factors for recurrence.
