本文提出的螺类控制主要指对传播曼氏血吸虫的双脐螺控制。1950年以来,血吸虫病控制经历了1950至1975年的螺控制和1975年至今的对终宿主的药物控制两个阶段。基于埃及、苏丹等国在实施灌溉计划前未认识螺类无法的生物学特性及其在传播血吸虫中的作用,留下失败的教训,有人即认为以控制螺类无法消灭血吸虫病,但也有人乐观地认为,在现代药物与杀螺剂出现之前,日本由于建造了内砌水泥的灌溉渠道,并使用了杀螺剂,消灭了血吸虫。50年代至70年代社区水平的血吸虫控制随合成的灭螺剂的不断
The snail control proposed in this paper mainly refers to the control of Schistosoma mansoni double snail transmission. Since 1950, schistosomiasis control has undergone spiral control from 1950 to 1975 and drug control of end-hosts from 1975 to the present. Based on the fact that Egypt, Sudan and other countries failed to recognize the biological characteristics of spirochaeta and its role in the transmission of schistosomiasis before the implementation of the irrigation plan, leaving some lessons for failure. Some people think that the control of spirochaeta can not eradicate schistosomiasis. However, some people It is optimistic that prior to the advent of modern drugs and narcotics, Japan had eliminated schistosomes as a result of the construction of internal irrigation channels and the use of snail killing agents. From the 1950s to the 1970s, community-level schistosomiasis was controlled by the continuous generation of molluscicides
