Kawasaki disease is the leading cause of acquired heart disease in children. Its incidence is underestimated in infants aged less than 1 year. In this population, clinical manifestations are atypical. The diagnosis should therefore be suspected in infants with persistent fever, even if not all clinical signs are present, in order to avoid delaying the diagnosis and treatment and prevent harmful cardiovascular consequences. Echocardiography is a helpful diagnostic tool and should be performed promptly in case of Kawasaki disease suspicion.
