Kawasaki Syndrome is an acute febrile illness that occurs predominantly in previously healthy young children. It is of unknown etiology and was first described in Japan in 1967. The illness carries an acute mortality rate of approximately 3 percent. The Centers for Disease Control defines Kawasaki Syndrome as a fever lasting five or more days for which no explanation can be found. Patients also must have at least four of the following symptoms: bilateral conjunctival infection; infected or fissured lips, pharynx, or a 'strawberry tongue'; erythema of the palms or soles, or edema of the hands or feet, or generalized or periungual desquamation; rash; and cervical lymphadenopathy.
