2009-2017年梧州市手足口病流行病学特征及时空聚集性分析

目的 分析2009-2017年梧州市手足口病流行特征和时空聚集特点,为防控工作提供理论依据。方法 收集《中国疾病预防控制信息系统》中2009-2017年梧州市网络直报的手足口病病例,使用Excel2013描述手足口病的流行病学特征,使用SaTScan9.6软件进行时空聚集性分析,使用ArcGIS10.2对分析结果进行可视化。结果 2009-2017年梧州市累计报告手足口病病例79 367例,发病率总体呈逐年上升,平均发病率263.1/10万。每年的4-7月和8-10月分别出现发病主高峰和次高峰。疫情高发地区是梧州市北部,男女性别比为1.56〖DK〗∶1,男性发病率(160.23/10万)高于女性(102.87/10万),0~5岁儿童占了发病总数的94.07%。2009-2017年梧州市手足口病发病在时间和空间存在明显的聚集性,聚集时间为每年的4-10月,一级聚集区和二级聚集区可重复出现在相同或相邻的乡镇。结论 梧州市手足口病发病率呈逐年上升趋势,部分地区存在显著的时空聚集性,在手足口病发病高峰时段应重点加强这些地区的防控。

Epidemiological characteristics and spatiotemporal clustering of hand,foot and mouth disease in Wuzhou,2009-2017

Objective To analyze the epidemiological characteristics and spatiotemporal clustering of hand,foot and mouth disease(HFMD)in Wuzhou from 2009 to 2017,and to provide evidence for the prevention and control of the disease.Methods The incidence data of HFMD in Wuzhou from 2009 to 2017 were collected from China information system for disease control and prevention.The epidemiological characteristics of HFMD were described by with Excel2013.The spatiotemporal clustering analysis was carried out with SaTScan9.6 software,and the analysis results were visualized with ArcGIS10.2.Results From 2009 to 2017,a total of 79367 cases of HFMD were reported in Wuzhou,with an overall incidence increasing year by year,the average incidence rate was 263.1/100000 population.The main peak and secondary peak occurred from April to July and August to October of respectively.The high incidence area of the epidemic was the northern part of Wuzhou city.The male-to-female sex ratio was 1.56〖DK〗∶1,the incidence rate of males(160.23/100000)was higher than that of females(102.87/100000),and children aged 0 to 5 years accounted for 94.07% of the total number of cases.From 2009 to 2017,the incidence of HFMD in Wuzhou had a significant aggregation in time and space.The significant clusters were from April to October every year.Primary clusters and secondary clusters were repeated every year in the same or adjacent town.Conclusion The incidence of HFMD in Wuzhou city is increasing year by year,some areas have significant temporal-spatial aggregation in some regions,during the peak period of HFMD,the prevention and control of these areas should be strengthened.
