text: Kawasaki<unk>  is diagnosed clinically (by medical signs and symptoms), and there are no specific confirmatory laboratory tests. It is normally difficult to establish the diagnosis, especially early in the course of illness, and frequently children are not diagnosed until they have seen a physician several times. Many other serious illnesses can cause similar symptoms, and must be considered in the differential diagnoses, including scarlet fever, toxic shock syndrome, and juvenile idiopathic arthritis. Classically, five days of fever plus four of five diagnostic criteria must be met in order to establish the diagnosis. These include mucositis (erythema of the palatine mucosa), fissured erythematous lips, "strawberry tongue", rash (polymorphus, usually urticarial erythematous rash mainly on extremities and/or trunk), changes in extremities (edema of hands and feet, erythema of palms & soles, desquamation of fingertips, bilateral non-exudative conjunctival erythema), and cervical lymphadenopathy of at least 15 milimeters.
