Kawasaki disease, or mucocutaneous lymph node syndrome, is a disease of unknown origin that most frequently (80% of the time) affects infants and children under 5 years of age. Accurate diagnosis and early therapeutic interventions, such as aspirin and intravenous γ-globulin can decrease the approximately 20% risk of developing coronary artery abnormalities. A specific diagnostic test does not exist. Thus, diagnosis of Kawasaki disease is based on characteristic clinical signs and symptoms, which are classified as principal clinical findings and other significant findings.
