摘  要:目的分析湖北省重点县人群血吸虫病乡村级尺度空间聚集性,为下阶段血吸虫病防控工作提供决策支持。方法以湖北省公安县、江陵县为代表,以乡村级尺度为研究单元,选取两县2015年血吸虫病粪便检查阳性病例(粪阳)和2016—2018年血吸虫病血清学检测阳性抗体效价在1∶80及以上(血阳高)病例为研究对象。采用Kulldorff圆形扫描统计量对人群血吸虫感染情况进行空间聚集性分析。结果公安县2015年粪阳病例,2016—2018年血阳高病例均在乡村级尺度上存在空间聚集性,其中以公安县沿长江流域分布的东北区域麻豪口镇、闸口镇、杨家厂镇、夹竹园镇、斗湖堤镇等5个流行乡镇覆盖的86个流行村最为突出。江陵县2015年粪阳病例,2016、2018年血阳高病例在乡村级尺度上均存在空间聚集性,其中以江陵县沿长江流域分布的西南区域普济镇、熊河镇等2个流行乡镇覆盖的57个流行村最为突出。结论湖北省公安县、江陵县的人群血吸虫病病情在乡村级尺度上存在空间聚集性,与以往研究相比,人群病例聚集性呈现缩小与下降趋势。故疫情现况对各地在推进血吸虫病消除工作进程中实施精准防治提出了更高要求。Objective To analyze the spatial clustering of human schistosomiasis at the village level in key counties in Hubei Province,to provide scientific evidence for formulating strategies for human schistosomiasis prevention and control in the next stage.Methods Gong′an County and Jiangling County in Hubei Province were selected as representative counties for this study.A town or village was set up as a research unit.Schistosomiasis cases of a positive fecal examination in 2015 and cases with positive detection for schistosomiasis serological antibody titer equal or above 80 in 2016-2018 were selected as research subjects in these two counties.The Kulldorff circular scan statistic was used for the spatial clustering analysis of human schistosomiasis infection status in the population.Results There was spatial clustering of positive schistosomiasis cases of fecal examination,at the level of a town or village in both counties in 2015.There was spatial clustering of positive human serological antibody detection at the level of town or village from 2016-2018.Eighty-six endemic villages in five towns in the northeast of Gong′an County,along the Yangtze river,including Mahaokou Town,Zhakou Town,Yangjiachang Town,Jiazhuyuan Town and Douhuti Town,were the most prominent.There was no spatial clustering of positive results of human serological antibody detection at the town and village level in Jiangling County,in2017,while there was spatial clustering of human serological antibody detection in 2016 and 2018,respectively.Fifty-seven endemic villages in two towns(Puji Town and Xionghe Town)in the southwest of Jiangling County,along the Yangtze river,were the most prominent.Conclusion There were spatial clustering of human schistosomiasis epidemic at village level both in Gong′an County and Jiangling County,Hubei Province.Compared with the previous studies,there was a trend of shrink and decline of clustering areas.Therefore,the current situation of the epidemic has put forward higher requirements for the implementation of p
