目的评价通江河道混凝土护坡综合治理控制血吸虫病的效果。方法选择便民河句容段为实验区,采用混凝土护坡和综合治理控制血吸虫病。选择3个监测点,对主、支流河道螺情,人、畜血吸虫病情,河水感染性等情况进行监测;设对照区采用常规防治措施加以比较。结果实验区2003年主河道连续4年查不到钉螺,支河道有螺面积较治理前下降了72.62%,有螺框出现率下降了87.31%,钉螺感染率下降了100.00%;未检出血吸虫病人、病畜,河水感染性监测为阴性。对照区主河道钉螺面积2003年较1998年增加51.49%,有螺框出现率下降46.32%,钉螺感染率为0.27%;支河道有螺面积增加2.41%,有螺框出现率下降58.64%,钉螺感染率为0.29%,人血吸虫病患病率为0.30%;牛血吸虫病患病率为5.66%,河水哨鼠感染率为59.00%。结论通江河道混凝土护坡综合治理控制血吸虫病效果非常显著。
Objective To evaluate the effect of comprehensive treatment of schistosomiasis by concrete slope protection in Tongjiang River. Methods The Minyong River Jurong Section was selected as the experimental area, and concrete slope protection and comprehensive treatment were used to control schistosomiasis. Three monitoring points were selected to monitor the predation of tributaries, river snails, human schistosomiasis and river water infectivity. The control areas were compared with conventional control measures. Results In 2003, the snail area was not found in the main channel of the experimental area for four consecutive years. The snail area in the branch channel decreased by 72.62% compared with that before treatment. The occurrence rate of snail box decreased by 87.31% and the infection rate of snails decreased by 100.00% Patients, sick animals, river water infectivity monitoring was negative. The area of snail in main channel of control area increased 51.49% from 2003 to 1998, the occurrence rate of snail box decreased 46.32% and the infection rate of snail was 0.27%. The area of snail supported by river increased 2.41% and the occurrence rate of snail box decreased 58.64% The infection rate was 0.29%, the prevalence rate of human schistosomiasis was 0.30%, the prevalence rate of bovine schistosomiasis was 5.66%, and the infection rate of river water sentinel disease was 59.00%. Conclusion Tongjiang River concrete slope protection comprehensive control of schistosomiasis effect is very significant.
