[Epidemiological and clinical characteristics of Kawasaki disease in Shanxi province].

Objective: The objective of this paper is to describe the epidemiological and clinical characteristics of Kawasaki disease (KD) in Shanxi province, China during a 5 year - period from January 1993 to December 1997.
Methods: A province - wide epidemiological survey on Kawasaki disease (KD) was carried ont by the China - Japan Kawasaki disease study group. The questionnaire form and the diagnostic criteria of KD which was prepared by the Japan Kawasaki disease research committee and translated into Chinese were sent of the departments of pediatrics of all the hospitals with 100 or more beds in Shanxi province. All the KD patients who were diagnosed during the observation period from 1993 to 1997 were asked to report to this survey. The database of reported KD in this survey was analyzed at the Department of pediatrics of the Shanxi provincial people's hospital, Xian, China. All the patients that satisfied the diagnostic criteria were included.
Results: A total of 105 (70%) hospitals responded and 376 cases of KD were confirmed. More cases were reported in 1993 and 1994. Of the total patients reported, 69% were children under 3 years old with male to female ratio of 1.6:1. The proportion of patients with cardiac sequelae was 19% with male to female ratio: 3:1. There were 4 fatal cases with a fatality rate of 1%.
Conclusions: Since KD is common in China continuous surveillance is necessary to maintain high awareness of KD so as to identify possible risk factors and its association with other disease.
