摘　　要：目的了解聊城市水痘流行病学特征及发病趋势,为制定防控策略提供依据。方法收集2008~2017年聊城市水痘病例发病时间、发病年龄、职业等资料,采用描述流行病学方法对其进行分析;应用ArcGis10.2、Geoda软件进行全局与局部空间自相关分析,对水痘发病空间聚集特征进行分析,找到发病“热点”地区及变迁规律。结果10年间聊城市累计报告水痘6923例,年平均发病率为11.78/10万。发病集中在冬、春季,高峰期发病(4274例)明显高于非高峰期(2649例)(P<0.01)。性别发病比为1.61∶1,男性明显多于女性病例(P<0.01);以0~12岁人群居多(5680例、82.00%),其中4~9岁组为高发年龄段(3630例、52.43%)。各类职业中,以学生、托幼儿童、散居儿童居多,占发病总数的91.33%。空间分布特征为发病“热点”地区主要集中在东昌府区,尤其以柳园街道、新区街道、古楼街道、东城街道最为明显。结论2008~2017年聊城市水痘发病历年变化不大,冬春季为发病季节高峰,4~9岁儿童为主要发病人群,发病主要集中在人口密度较大的城区。Objective To understand the epidemiological characteristics and incidence trend of varicella in Liaocheng city,so as to provide the evidence for formulating prevention and control strategies.Methods The data of time,age and occupation of the varicella cases in Liaocheng city were collected during 2008-2017 and analyzed by descriptive epidemiological method.Using Arc Gis 10.2 and Geoda software,the information of varicella epidemic situation in Liaocheng city was taken as a global and local spatial autocorrelation.The spatial clustering characteristics of varicella were analyzed,and the"hot spot"areas and changing rules were found.Results During the 10 years,a total of 6923 cases of varicella were reported,with an average annual incidence of 11.78/10~5.The incidence was concentrated in winter and spring.The number of cases in peak period(4274 cases)was significantly higher than the non-peak period(2649 cases)(P<0.01).The sex incidence ratio was 1.61∶1,and the male had significantly higher incidence than the female(P<0.01);cases concentrated in children aged 0-12 years old(5680 cases,82.00%),mainly those aged 4-9 year old(3630 cases,52.43%).Among all kinds of occupations,students,childcare children and scattered children accounted for 91.33%.The feature of spatial distribution showed that the area of"hot spot"was mainly concentrated in Dongchangfu district,especially in Liuyuan street,Xinqu street,Gulou street and Dongcheng street.Conclusion From 2008 to 2017,there is little change in the incidence of varicella in Liaocheng city.The peak season is winter and spring.Children aged 4-9 years are the main population.The varicella cases are mainly concentrated in urban areas with large population density.
