在过去的五十年里,血吸虫病的分布情况发生了变化,并且也有一些成功的防治项目,但据估计,感染或有感染风险的人数并没有减少。如今,据估计85%的感染者在非洲大陆,而那里几乎没有采取什么防治措施。因此,就疾病负担而言,撒哈拉以南非洲地区与世界其他地区之间的差距越来越大。世界卫生组织现在制定了一项控制血吸虫病的双重策略:一种是适应高负担地区公共卫生状况的控制发病率的策略,另一种是在已达到低流行水平且有可能实现消除的地区巩固控制的策略。基于这一新的愿景,一些研究需求被指出。
While the distribution of schistosomiasis has changed over the last fifty years and there have been successful control programmes, the number of people estimated to be infected or at risk of infection has not been reduced. Today, 85% of the number of infected people are estimated to be on the African continent where few control efforts are made. In terms of disease burden, there is therefore a growing discrepancy between sub-Saharan Africa and the rest of the world. WHO has now developed a dual strategy for the control of schistosomiasis: a strategy for morbidity control adapted to the public health context in high burden areas, and a strategy to consolidate control in areas where a low endemic level has been reached and elimination may be feasible. Related to this new vision, some research needs are pointed out.
