2008-2017年湖北省荆州市手足口病时空特征分析

Spatial-temporal distribution characteristics of hand, foot and mouth disease in Jingzhou, Hubei, 2008–2017

目的分析2008-2017年湖北省荆州市手足口病时空分布特征,为手足口病防控工作提供依据。方法在街道/乡镇尺度采用ArcGIS 10软件对手足口病发病数据空间聚集性进行全局和局部自相关分析,采用SaTScan 9.4软件对手足口病发病数据时空聚集性进行分析。结果荆州市累计报告发病53 159例,年平均发病率为91.59/10万。空间自相关分析显示,发病率存在空间正相关,主聚集区域位于荆州市中心城区及周边县(市)与其接壤的乡镇,发病率存在明显时空聚集性特征。结论在街道/乡镇尺度上掌握荆州市手足口病发病数据的空间分布、时空聚集等分布特征,对于合理配置公共卫生资源、有效预防和控制手足口病有重要公共卫生学意义。

Objective To analyze the spatial-temporal distribution characteristics of hand,foot and mouth disease(HFMD)in Jingzhou,Hubei province,from 2008 to 2017,and provide evidence for the prevention and control of HFMD.Methods The global and local autocorrelation analyses on the spatiotemporal clustering of the incidence data of HFMD at street/township scale in Jinzhou during this period were performed by using software ArcGIS 10,and the spatiotemporal clustering analysis on the incidence data of HFMD was performed by using software SaTScan 9.4.Results A total of 53 159 cases were reported in Jingzhou from 2008 to 2017,with an average annual incidence rate of 91.59/100 000.Spatial autocorrelation analysis showed that the incidence rate of HFMD had positive spatial correlation.The incidence rate of HFMD had obvious spatiotemporal clustering characteristics,the main clustering area was found in the central urban area of Jingzhou and adjacent counties and townships.Conclusion Understanding the spatial and temporal distribution and spatial clustering characteristics of the incidence data of HFMD at street/township scale in Jingzhou has important public health significance for the allocation of public health resources,effective prevention and control of HFMD.
