Schistosomiasis remains one of the most prevalent parasitic diseases in developing countries. After malaria, schistosomiasis is the most important tropical disease in terms of human morbidity with significant economic and public health consequences. Although schistosomiasis has recently attracted increased focus and funding for control, it has been estimated that less than 20% of the funding needed to control the disease in Africa is currently available. In this article the following issues are discussed: the rationale, development and objectives of the Schistosomiasis Control Initiative (SCI)-supported programmes; the management approaches followed to achieve implementation by each country; mapping, monitoring and evaluation activities with quantifiable impact of control programmes; monitoring for any potential drug resistance; and finally exit strategies within each country. The results have demonstrated that morbidity due to schistosomiasis has been reduced by the control programmes. While challenges remain, the case for the control of schistosomiasis has been strengthened by research by SCI teams and the principle that a national programme using 'preventive chemotherapy' can be successfully implemented in sub-Saharan Africa, whenever the resources are available. SCI and partners are now actively striving to raise further funds to expand the coverage of integrated control of neglected tropical diseases (NTDs) in sub-Saharan Africa.
血吸虫病仍然是发展中国家最流行的寄生虫病之一。在疟疾之后,血吸虫病是对人类发病率影响最大的热带病,对经济和公共卫生有重大影响。尽管血吸虫病最近受到了更多的关注和控制资金,但据估计,目前用于控制非洲血吸虫病的资金还不到所需资金的 20%。本文讨论了以下问题:血吸虫病控制倡议(SCI)支持的方案的基本原理、制定和目标;为实现每个国家的实施而采取的管理方法;具有量化控制方案影响的绘图、监测和评估活动;监测任何潜在的药物耐药性;以及每个国家的最终退出策略。结果表明,控制方案已降低了血吸虫病的发病率。虽然仍面临挑战,但 SCI 团队的研究以及以下原则加强了控制血吸虫病的理由,即只要有资源,就可以在撒哈拉以南非洲成功实施使用“预防性化疗”的国家方案。SCI 和合作伙伴目前正在积极努力筹集更多资金,以扩大撒哈拉以南非洲被忽视的热带病(NTDs)综合控制的覆盖范围。
