The aim of this study was to estimate the incidence and describe the epidemiological characteristics of Kawasaki disease among children in Korea.


Questionnaires for surveying the epidemiology of Kawasaki disease were distributed to a total of 101 hospitals that conduct pediatric residency programs. Then, we retrospectively obtained the data, which covered a three-year period (2006-2008) and analyzed them.


During the three-year study period, a total of 9039 cases of Kawasaki disease were reported from 84 hospitals (response rate, 83.2%), comprising 5375 boys and 3664 girls (male:female ratio, 1.47:1). The outbreak rate per 100,000 children <5 years old was 108.7 in 2006, 118.3 in 2007 and 112.5 in 2008 (average rate, 113.1). The seasonal distribution showed a slightly higher incidence rate in winter and summer. The patients' mean age of onset was 32.6 months, while the proportions of sibling cases and recurrent cases were 0.17% and 2.2%, respectively. Coronary arterial abnormalities were detected during follow up by echocardiogram in 17.5% of all cases including dilatations (16.4%) and aneurysms (2.1%).


The average annual incidence rate of Kawasaki disease in Korea has been continuously increasing, and reached 113.1/100,000 children <5 years old, which is the second highest rate in the world.
