【摘要】 目的评估江苏省国家血吸虫病监测点疫情,为进一步完善敏感可靠的血吸虫病监测体系提供参考。方法 2015—2019年江苏省根据《全国血吸虫病监测方案(2014年版)》的要求开展血吸虫病监测工作,对历年的病情和螺情进行描述性及空间聚集性分析。结果 2015—2019年江苏省本地人群平均血检阳性率为1.55%,流动人群平均血检阳性率0.51%;2016年本地人群血检阳性率相较2015年增长46.45%,其余年份均呈现下降趋势;每年本地人群的血检阳性率均高于流动人群(χ~2=42.74、120.51、74.50、73.67和60.64,P均<0.01),未查到粪检阳性患者。年均查出有螺面积229.60 hm~2,其中新发面积1.75 hm~2,复现面积57.22 hm~2,钉螺密度0.013 0只/0.1m~2,未查到感染性钉螺。钉螺面积和钉螺密度有所升高,历年钉螺聚集区主要在宁镇扬(南京、镇江、扬州)一带。结论近年来江苏省采取的血防策略显著推动了全省血吸虫病传播阻断达标进程,今后需继续健全监测体系,防止血吸虫病疫情反弹。更多还原

【Abstract】 Objective To evaluate the endemic situation of schistosomiasis prevalence in the national surveillance sits in Jiangsu Province for guidelines to improve the surveillance system that can be reliable and sensitive.Methods By the requirements in the National Schistosomiasis Monitoring Scheme(2014 Edition),we conducted monitoring over schistosomiasis prevalence in Jiangsu Province from 2015 through 2019,and analyzed the surveillance data, including infection rate in population, areas with snails by statistics and spatial clustering.Results The average seropositive rate for schistosomiasis was 1.55% in local residents and 0.51% in floating population between 2015 and 2019.The seropositive rate was increased by 46.45% in 2016 compared to that in 2015 and then showed a decreasing trend.Nevertheless, annul seropositive rate was higher in local residents than in floating population(χ~2=42.74,120.51,74.50,73.67 and 60.64,respectively, all P<0.01).No positive case was detected by fecal test.Annual survey revealed average snail areas being 229.60 hm~2,where snails were emerged in 1.75 hm~2,and re-emerged in 57.22 hm~2.The yearly average snail density was 0.013 0/0.1 m~2.No infected snails were found.Snail areas and snail density was increased to a certain degree, and snail areas were mainly limited within the regions of Nanjing-Zhenjiang-Yangzhou Town.Conclusion Schistosomiasis control strategies in Jiangsu in the past years have produced obvious effects on the way to the criteria of schistosomiasis interruption across the province.However, the surveillance system should be perfected in following prevention and control work in order to prevent reemergence of schistosomiasis.更多还原
