摘　　要：目的基于地理信息系统(geographic information system,GIS)技术分析2008-2017年贵港市手足口病的流行病学特征,为该市手足口病的防控提供科学依据。方法调用2008-2017年贵港市手足口病的监测数据及人口数据,以乡镇为单位,采用SPSS 19.0和ArcGIS 10.2软件分析手足口病的流行病学特征。结果2008-2017年贵港市手足口病累计发病67520例,年均发病率为126.99/10万,发病高峰期基本呈现双高峰状态,第一发病高峰在4~7月,次峰在9~10月。0~5岁儿童为主要发病人群,占86.97%;男性发病高于女性,男女性别比1.62∶1。GIS地图显示2008-2017年贵港市手足口病大部分集中在西南部,其次是东北部。全局自相关显示,手足口病发病存在空间聚集性。趋势面分析,手足口病总体分布由东向西,由北向南逐渐升高。结论贵港市手足口病处于高发、增长态势,小于5岁的男性儿童为高危人群;每年发病呈双峰;地区分布集中在西南部和东北部。Objective To understand the epidemiological features of hand-foot-mouth disease(HFMD)in Guigang with GIS technology,to provide scientific basis for the prevention and control of HFMD.Methods The monitoring and demographic data of HFMD in Guigang from 2008 to 2017 were collected.Take township as unit,SPSS 19.0 and ArcGIS 10.2 were used to analyze the epidemiological characteristics of HFMD.Results A total of 67520 cases of HFMD were reported from 2008 to 2017.The average annual incidence rate was 126.99/100000.The incidence took on double peak phenomenon,with the first peak from April to July and the secondary peak from September to October.Most cases focused on children aged 0~5 years old,accounting for 86.97%.And the incidence rate of male was higher than that of female,with a sex ratio of 1.62∶1.GIS map showed that the incidence was mainly concentrated in southwest followed by northeast from 2008 to 2017.The global spatial autocorrelation showed that the incidence of HFMD existed spatial aggregation in Guigang.The trend surface analysis showed that the overall distribution of HFMD gradually increased from east to west and from north to south.Conclusion The incidence of HFMD in Guigang was at an increasing rate.Most cases focused on children aged less than 5.The annual incidence showed a double peak.And the incidence is mainly concentrated in southwest followed by northeast.
