Among the measures used in attempts to control the snail host of S. japonicum in Leyte Province, Philippines, where the terrain is unsuited to the application of molluscicides, have been removal of vegetation in and around infested streams, drainage of water-logged areas, filling low-lying areas with earth or flooding them, and digging fishponds in sluggish streams. Each of these measures is described in detail.Experiments carried out in rice-fields, which harbour great numbers of snails, have shown that improvements in rice-growing methods will not only markedly reduce the snail population but also double the rice yield.A campaign to promote the use of pit latrines encountered the serious difficulty that such latrines were not acceptable to the people. However, there is evidence that use of pit latrines does bring about a reduction in snail infection rates.No single control measure is recommended for all snail habitats, the choice of method depending on local circumstances; in many areas a combination of methods proved advantageous. It is felt that mass treatment of infected persons would not be fully effective until transmission is more thoroughly under control.
在菲律宾莱特省，由于地形不适于使用杀螺剂，人们采取了多种措施来控制日本血吸虫的螺蛳宿主，包括清除受感染溪流及其周边的植被、排干涝渍地区的积水、用泥土填埋低洼地区或使其被水淹没，以及在水流缓慢的溪流中挖掘鱼塘。文中对每一项措施都进行了详细描述。在螺蛳大量滋生的稻田里进行的实验表明，改进水稻种植方法不仅能显著减少螺蛳数量，还能使水稻产量翻番。一场推广使用坑式厕所的运动遇到了严重困难，即这种厕所不被人们接受。然而，有证据表明使用坑式厕所确实能降低螺蛳感染率。并非所有螺蛳栖息地都推荐采用单一的控制措施，方法的选择取决于当地情况；在许多地区，多种方法结合使用被证明是有利的。人们认为，在传播得到更彻底控制之前，对感染者进行大规模治疗不会完全有效。
