Results of an International Cooperative Study on Kawasaki Disease

Kawasaki disease is a febrile illness of unknown etiology affecting mainly children under 5 years of age—20% of whom develop coronary artery aneurysms. Cases have been reported worldwide, and epidemics apparently occur every 2–3 years. Its annual rate (in passive surveillance systems) in nonepidemic times appears to be in the area of 1–10 per 100,000 children below 5 years of age.
