To understand the epidemiologic characteristics and spatial-temporal distribution of hepatitis E in Shanghai between 2006 and 2016. The reported incidence of hepatitis E and health facilities' information between 2006 and 2016 were collected from the China Information System for Disease Control and Prevention. The geographic information were from Shanghai Surveying and Mapping Institute. The map scale was 1∶750 000. Global and local autocorrelation, and spatial-temporal detection methods were applied to determine the spatial-temporal characteristics of hepatitis E. Software ArcGIS 10.1 was used to analyze global and local spatial auto correlation of hepatitis E spatial clusters. Software SaTScan 9.4.4 was used to conduct scan for exploring the areas of hepatitis E temporal spatial clusters. A total of 6 048 cases of hepatitis E were reported in Shanghai during 2006-2016. The average incidence was 2.14/100 000. Spatial auto correlation analysis indicated that there was significant spatial positive correlations and spatial-temporal clustering of hepatitis E in Shanghai, and the "high-high cluster" was mainly located in the downtown of the city. Understanding the spatial-temporal clustering areas of hepatitis E cases in Shanghai from 2006 to 2016 is important to the reasonable allocation of public health resources and effective prevention and control of hepatitis E.
为了解2006年至2016年上海市戊型肝炎的流行病学特征及时空分布。从中国疾病预防控制信息系统收集2006年至2016年戊型肝炎报告发病率及医疗机构信息。地理信息来自上海市测绘院,地图比例尺为1∶750 000。应用全局和局部自相关以及时空探测方法确定戊型肝炎的时空特征。采用ArcGIS 10.1软件分析戊型肝炎空间聚集的全局和局部空间自相关。使用SaTScan 9.4.4软件进行扫描以探索戊型肝炎时空聚集区域。2006 - 2016年上海市共报告戊型肝炎病例6048例,平均发病率为2.14/10万。空间自相关分析表明,上海市戊型肝炎存在显著的空间正相关及时空聚集,“高高聚集”主要位于市中心城区。了解2006年至2016年上海市戊型肝炎病例的时空聚集区域对于合理配置公共卫生资源及有效防控戊型肝炎具有重要意义。
