过去十年内,巴西、埃及、加纳、马达加斯加、菲律宾、津巴布韦、坦桑尼亚、委内瑞拉及其它地区的许多血吸虫病防制项目已证明,单独使用灭螺药物或结合其它方法(化疗、环境措施、卫生教育等)控制螺类,是减少或消灭血吸虫病传播的迅速而有效的方法。因此,即使在将来选择性的人群化疗可能在综合防制策略中处于主导地位,灭螺方法(包括药物灭螺)必定仍然在血吸虫病防制措施中保持其优选地位。1965年世界卫生组织支持撰 Many schistosomiasis control programs in Brazil, Egypt, Ghana, Madagascar, the Philippines, Zimbabwe, Tanzania, Venezuela and elsewhere over the past decade have demonstrated that snail-killing drugs alone or in combination with other methods (chemotherapy, environmental measures, health education, etc.) Control snails are quick and effective ways to reduce or eliminate the spread of schistosomiasis. Therefore, even if selective population chemotherapy is likely to dominate an integrated control strategy in the future, snail-killing methods, including drug snails, must still retain their preferred status in schistosomiasis control measures. 1965 World Health Organization support essays
