摘　　要：目的对上海市松江区2018—2022年其他感染性腹泻病例开展时空聚集性分析,为科学防控肠道传染病提供数据支持。方法收集2018—2022年上海市松江区其他感染性腹泻监测资料,使用ArcMAP 10.7进行空间自相关分析,使用SaTScan 10.1.2进行时空扫描分析。结果2018—2022年,松江区累计报告其他感染性腹泻病例2996例,年均发病率为29.26/10万。病例男女性别比为1.24∶1,以0~4岁年龄组(44.91%)最多见,职业以散居儿童(42.36%)、学生(9.91%)、托幼儿童(8.98%)为主。空间自相关分析结果显示,2018—2021年松江区其他感染性腹泻呈现正相关性。发病热点区集中于松江区主城区的方松街道、岳阳街道、中山街道、永丰街道。时空扫描分析探测到三个时空聚集区:一类聚集区位于主城区的四个街道(RR=4.06,LRR=515.06,P<0.05),二类聚集区位于东北部的2个街镇(RR=2.59,LRR=12.04,P<0.05),三类聚集区位于主城区及西北部的4个街镇(RR=2.65,LRR=11.51,P<0.05)。结论2018—2022年,松江区其他感染性腹泻发病整体呈波动下降趋势,且存在一定的时空聚集性,应在流行季前在聚集区加强对重点人群的防控措施。Objective To analyze the spatial-temporal aggregation of other infectious diarrhea(OID)in Songjiang District,Shanghai,from 2018 to 2022,and to provide a basis for the formulation of scientific prevention and control measures of intestinal infectious disease.Methods Surveillance data of OID cases in Songjiang District,Shanghai,from 2018 to 2022 were collected from China Information System for Disease Control and Prevention.ArcMap software version 10.7 was applied to detect spatial autocorrelation analysis,and SaTScan software version 10.1.2 was applied in spatial-temporal scan analysis.Results A total of 2996 OID cases were reported in Songjiang District between 2018 and 2022,with an average annual incidence rate of 29.26/100000.The sex ratio of OID cases was 1.24∶1,and majority of cases occurred in the age group 0-4 years(44.91%).Occupation of OID cases was mainly scattered children(42.36%),students(9.91%)and children in kindergarten or nursery(8.98%).Positive spatial autocorrelation of OID between 2018 and 2021 was identified at the township level in the global spatial autocorrelation analysis.Local spatial autocorrelation analysis indicated that the hotspot areas of OID incidence were Fangsong Street,Yueyang Street,Zhongshan Street and Yongfeng Street,respectively,which were all distributed in the main urban area of Songjiang District.Three high-risk spatial-temporal clusters of OID incidence were identified through the spatial-temporal scan analysis.The primary spatial-temporal cluster covered 4 streets in the main urban area of Songjiang(RR=4.06,LRR=515.06,P<0.05).The secondary spatial-temporal cluster covered 2 streets/towns in northeastern area of Songjiang(RR=2.59,LRR=12.04,P<0.05).The tertiary spatial-temporal aggregation areas covered 4 streets/towns in both northwestern and main urban area of Songjiang(RR=2.65,LRR=11.51,P<0.05).Conclusion From 2018 to 2022,the overall incidence of other infectious diarrhea in Songjiang District showed a fluctuating downward trend,and there was a certain degree of spat
