OBSERVATION ON THE EFFECT OF DIFFERENT STRATEGIES TO CONTROL INFECTION SOURCES OF SCHISTOSOMIASIS AND CONTAMINATION IN RIVER BEACH REGIONS

目的江滩地区不同防治对策控制血吸病传染源及滩地污染效果的观察。方法根据江滩地区血吸虫病流行特点,分别实施“人畜化疗+健康教育”及“江滩综合治理+人畜化疗+健康教育”策略。与实施一般防治对策的对照试区进行效果比较。结果表明各试区人群血吸虫感染率下降了80％以上,感染度下降了90％以上,耕牛血吸虫感染率下降了70％;滩地野粪阳性率显著下降。滩地污染得到有效控制。结论“人畜化疗+健康教育”及“江滩综合治理+人畜化疗+健康教育”策略。较实施一般防治对策的对照试区更能有效地控制传染源,人畜血吸虫感染率显著下降。

Object Observation on the effcct of different strategies to control infection sources of schistosomiasis and contamination in river beach regions. Methods According to the epidemiological characeristics of schistosomiasis in river beach regions, we made and carried out different control strategies "chemotherapy + thealth edvcation" or "beach harnessingt + chemotherapy + health education. " then comparing it with the areas where general control strategy was carried out. Results The results showed that the people’s infection rate with schistosma japonicum reduced more than 80%, the infectiosity reduced more than 90%, the infection rate of cattle reduced more than 70%; the infection rate of wild faeces declined remarkably, the contaminaion in beach was controlled effectively. Conclusion Control strategies of "chemotherapy + health education" or "beach harnessing + chemotherapy + health education" was carried out in river beach regions, both of them cauld control the infection sources of schistosomiasis and contamination effectively.
