摘　　要：目的了解合溪水库兴建后流域内血吸虫病疫情变化。方法 2012-2015年选择合溪水库北涧入口处煤山镇新源村作为监测点,按照《浙江省血吸虫病监测点监测方案》的方法,对监测点内人畜血吸虫病病情和螺情开展监测。结果2012-2015年监测点内累计调查167个环境,面积21.68 hm^2,查到有螺条块2个,面积0.1 hm^2,有螺框出现率为0.12%,活螺密度为0.019 2只/0.1 m2,解剖钉螺374只,未发现血吸虫感染性钉螺;监测本地居民970人,流动人群8 748人,未发现血吸虫感染病人;监测黄牛3 085头,未发现血吸虫感染病牛。结论合溪水库流域血吸虫病疫情稳定,内源性血吸虫病传染源已消除;应加强输入性血吸虫病疫情监测,加大合溪水库流域螺情监测和环境改造力度,有效压缩钉螺面积。Objective To understand the changes of schistosomiasis epidemic situation,so as to provide the evidence for formulating schistosomiasis control strategy in the Hexi reservoir area. Methods From 2012 to 2015,Xinyuan Village,Meishan Town in the north entrance of Hexi reservoir was selected as a monitoring site. According to the requirements of the monitoring program of schistosomiasis surveillance in Zhejiang Province,the Schistosoma japonicum infection was investigated by using the serological screening（IHA）,and the basic situation of the surveillance site was also investigated. Results From 2012 to2015,167 environments（21.68 hm^2）were surveyed,and 2 slices（0.1 hm^2）were found with Oncomelania hupensis snails. The detection rate of frames with snails was 0.12%,and the living snail density was 0.0192 snails per 0.1 m2. Totally 374 snails were dissected and no schistosome infected snails were found. A total of 970 local residents and 8 748 mobile people were investigated with the serological tests,and no schistosome infected people were found. In addition,3 085 cattle were investigated and no infected ones were found. Conclusion The schistosomiasis epidemic situation is stable in the Hexi reservoir area,but we still should strengthen the monitoring of imported source of infection and snail status,and increase the efforts of environmental transformation.
