目的探讨安徽省2004-2015年甲型病毒性肝炎(简称“甲肝”)发病的时空分布特点。方法从传染病报告信息管理系统收集安徽省2004-2015年甲肝疫情监测资料,使用MapInfo建立甲肝疫情地理信息系统(Geographic Information Systems,GIS)数据库。应用空间统计分析软件(GeoDa 1.8.12)对建立的GIS数据库进行全局和局部空间自相关分析;用时间-空间扫描统计软件(SaTScan 9.4.4)进行时空扫描统计。结果安徽省2004-2015年共报告甲肝病例17 194例。2004-2014年甲肝发病存在着显著的空间聚集,共探测到61个高-高聚集区;时空扫描统计探测到5个时空聚集区;这些聚集区大部分位于安徽省的沿淮河流域、长江流域和北部的部分县区。结论安徽省甲肝发病存在时空聚集性。
Objective To investigate the spatio-temporal distribution of hepatitis A virus in Anhui Province from 2004 to 2015. Methods A surveillance data of hepatitis A in Anhui Province from 2004 to 2015 was collected from the information system of infectious disease reporting and a database of Geographic Information Systems (GIS) of the outbreak of hepatitis A was established using MapInfo. The spatial and statistical analysis software (GeoDa 1.8.12) was used to conduct global and local spatial autocorrelation analysis on the established GIS database. Spatial and temporal scanning statistics were obtained using time-space scanning statistical software (SaTScan 9.4.4). Results A total of 17 194 hepatitis A cases were reported in Anhui Province from 2004 to 2015. In 2004-2014, there were significant spatial aggressions of Hepatitis A, a total of 61 high-high agglomeration areas were detected. Five spatiotemporal accumulation areas were detected by spatio-temporal scanning statistics. Most of these areas were located in the Huaihe River Basin in Anhui Province and the Yangtze River Basin And the northern part of the county. Conclusion There is spatiotemporal aggregation of hepatitis A in Anhui province.
