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 epidemic situation of schistosomiasis in watershed after the construction of the Hexi Reservoir. Methods From 2012 to 2015, Xinyuan Village, Coal Town, Beijian, Hexi Reservoir was selected as the monitoring point. According to the monitoring program of schistosomiasis surveillance in Zhejiang Province, the condition and snail status of human and animal schistosomiasis in the monitoring sites were monitored . Results A total of 167 environments with an area of 21.68 hm ~ 2 were surveyed from 2012 to 2015. There were 2 snail patches with an area of 0.1 hm ~ 2, a screw frame with a rate of 0.12% and a live spiral density of 0.019 2 Only /0.1 m2, 374 snails were dissected, and no snails infected with schistosomiasis were found. 970 local residents and 8 748 floating population were detected. No schistosoma infection was found in the samples. A total of 3 085 cattle were monitored. Conclusions The epidemic situation of schistosomiasis in the co-Hexi reservoir area is stable and the source of infection of endogenous schistosomiasis has been eliminated. The epidemic situation of imported schistosomiasis should be strengthened, the monitoring of snail infection and the environmental improvement should be intensified, and the snail area should be effectively compressed.
