title: Epidemiologic survey of Kawasaki disease in Inner Mongolia, China, between 2001 and 2013.
abstract: The epidemiologic features of Kawasaki disease (KD) in the Inner Mongolia Autonomous Region of China has not been previously determined, to the best of our knowledge. Therefore, the aim of the present study was to investigate the epidemiology of KD in Inner Mongolia. Clinical data from 518 patients treated for KD in Inner Mongolia between January 2001 and December 2013 were analyzed. The results indicated that the mean annual incidence rate was 3.55±2.96 per 100,000 children under the age of 5 years between 2001 and 2013. The age at diagnosis ranged between 49 days and 14 years, while the disease occurred more frequently in the spring and summer. In addition, the incidence of coronary artery lesion (CAL) was reported to be 40.2% in the present survey. KD patients in the Han Chinese ethnic group were more likely to be complicated by CAL, whereas patients with incidence of KD in July were less likely to be complicated by CAL. In conclusion, the incidence of KD was observed to be increasing in Inner Mongolia, while the ethnic group and month of onset may be associated with the incidence of CAL in KD patients.
