摘　　要：目的了解聊城市流行性感冒流行病学特征及时空聚集性特征,为流感的防控提供科学依据。方法描述性流行病学方法分析2019年全市流行性感冒疫情资料三间(人间、时间、空间)分布;使用SaTScan v 9.6进行时空聚集性分析。结果2019年聊城市报告流行性感冒病例10160例,年发病率为167.26/10万。报告病例居前3位的县(市、区)分别为东昌府区(5892例)、阳谷县(888例)、茌平区(871例)。全年有3个发病高峰,分别为1、4和12月。男性发病率(186.04/10万)高于女性(147.42/10万)(P<0.01)。发病年龄以10岁以下儿童为主,占病例总数的76.37%。病例以散居儿童发病为主,其次为学生、幼托儿童,分别占病例总数的41.90%、22.00%、18.63%。时空扫描分析显示高发聚集地区主要集中在东昌府区,高发聚集时间主要集中在12月(RR=15.99、对数似然比=3780.32,P<0.01)。结论聊城市流行性感冒发病具有明显时空聚集区。Objective To understand the epidemiological characteristics and spatio-temporal aggregation analysis of influenza in Liaocheng city,so as to provide scientific basis for the control and prevention of the disease.Methods Descriptive epidemiological method was used to analyze the distribution of influenza epidemic data in epidemic distribution in human,time and space in the whole city in 2019.SaTScan v 9.6 was used for spatial-temporal aggregation analysis.Results A total of 10160 cases were reported in Liaocheng city in 2019,with the annual incidence of 167.26/105.The top 3 counties with the highest number of cases were Dongchangfu district(5892 cases),Yanggu county(888 cases)and Chiping district(871 cases).There were 3 peaks in the whole year,January,April and December.The incidence of male(186.04/105)was higher than that of female(147.42/105)(P<0.01).The casesmainly distributed in children aged under 10 years old,accounting for 76.37%of the total cases.The cases concentrated in scattered children,followed by students and children in kindergartens,accounting for 41.90%,22.00%and 18.63%of the total cases respectively.Spatiotemporal scanning analysis shows that the high incidence areas were mainly concentrated in Dongchangfu district,and the time of high incidence was mainly in December(RR=15.99,LLR=3780.32,P<0.01).Conclusion The incidence of influenza in Liaocheng city has obvious time and space gathering area,so the prevention and control efforts should be strengthened in critical areas.
