摘要
目的探讨2013-2015年湖南省毒蘑菇中毒的时空分布和聚类特征,为科学防控毒蕈中毒提供依据。方法以湖南省2013-2015年毒蕈中毒事件的监测数据为研究对象,利用ArcGIS10.2软件建立病例地理信息数据库,采用OpenGeoDa进行全局、局部空间自相关分析。SaTScan 9.1.1进行时空扫描聚类,结果通过ArcGIS10.2进行可视化展示。结果 2013-2015年湖南省共报告毒蕈中毒事件136起,发病人数565人,中毒高峰为每年5~9月。趋势面分析显示毒蕈中毒发病率总体分布由西向东逐渐降低,由南向北先增加再降低。局部空间自相关结果显示冷水滩区、零陵区为高-高区域;芷江侗族自治县、新宁县、湘乡市为低-高区域;新晃侗族自治县、鹤城区、洞口县为高-低区域。时空扫描发现所有聚类时间段集中在2015年6月~9月,一类聚集区主要位于邵阳市、怀化市、永州市。二类聚集区位于长沙市、湘潭市。结论湖南省毒蕈中毒存在时空聚集性,各时空聚集区将为探索有针对性的防控措施提供参考。
Objective To analyze the spatial distribution of mushroom poisoning in Hunan province from 2013 to 2015, so as to provide scientific evidence for control strategy. Methods Data of mushroom poisoning events in Hunan Province from 2013 to 2015 were collected. Based on geographical information system database ,which Constructed by ArcGIS 10.2 , conducting retrospective time -space analysis（via SaTScan9.1.1） and autocorrelation analysis（via OpenGeoDa） to detect the spatial and spatio-temporal clusters of mushroom poisoning cases. Results There were 136 mushroom poisoning events reported from 2013 to 2015, including 565 patients. The poisoning peak occurred in 5-9th month annually. According to the local Moran’’’’’’’’’’’’’’’’s I, Lengshuitan, Lingling lay in high-high region; Zhijiang, Xinning, Xiangxiang lay in low-high region; xinhuang, Hecheng, Dongkou lay in high-low region. All the spatio-temporal clusters were between 2015/6-2015/9, the most likely cluster was in Shaoyang, Huaihua, Yongzhou. The secondary cluster included Changsha, Xiangtan. Conclusion There are significant spatio-temporal cluster pattern for the distribution of mushroom poisoning in Hunan, which could provide reference for the futher target prevent and control.
