The World Health Organization (WHO) recognizes schistosomiasis as one of the Neglected Tropical Diseases targeted for global elimination in the 2030 Agenda of the Sustainable Development Goals. In Brazil, schistosomiasis mansoni is considered a public health problem, particularly prevalent among vulnerable populations living in areas with poor environmental and sanitary conditions. In 2022, the WHO published a Guideline encompassing recommendations to assist national programs in endemic countries in achieving morbidity control, eliminating schistosomiasis as a public health problem, and advancing towards interrupting transmission. The perspectives presented here, collectively prepared by members of the Oswaldo Cruz Foundation's (Fiocruz) Schistosomiasis Translational Program (FioSchisto), along with invited experts, examine the feasibility of the WHO recommendations for the Brazilian settings, providing appropriate recommendations for public health policies applicable to the epidemiological reality of Brazil, and suggests future research to address relevant issues. In Brazil, the provision of safe water and sanitation should be the key action to achieve schistosomiasis elimination goals. The agencies involved in measures implementation should act together with the Primary Care teams for planning, executing, monitoring, and evaluating actions in priority municipalities based on their epidemiological indicators. Host snails control should prioritize judicious ecological interventions at breeding sites. The Information, Education, and Communication (IEC) strategy should be associated with water and sanitation and other control actions, actively involving school community. To identify infected carriers, FioSchisto recommends a two-stage approach of immunological and molecular tests to verify transmission interruption during the intervention and beyond. Praziquantel administration should be done under medical supervision at the Primary Care level. MDA should be considered in exceptional settings, as a measure of initial attack strategy in locations presenting high endemicity, always integrated with water and sanitation, IEC, and snail control. To assist decision-making, as well as the monitoring and evaluation of strategic actions, there is a need for an Information System. FioSchisto considers this systematization essential to make investments in strategic research to support the improvement of schistosomiasis control actions. Efforts toward schistosomiasis elimination in Brazil will succeed with a paradigm shift from the vertical prescriptive framework to a community-centered approach involving intersectoral and interdisciplinary collaboration.
世界卫生组织(WHO)将血吸虫病列为 2030 年可持续发展目标议程中需要消除的 10 种被忽视热带病之一。在巴西,曼氏血吸虫病被认为是一个公共卫生问题,尤其在生活在环境和卫生条件差的脆弱人群中普遍存在。2022 年,世界卫生组织发布了一份指南,其中包含了为协助流行国家的国家规划实现发病率控制、消除血吸虫病作为公共卫生问题以及推进传播中断的建议。这里提出的观点是由奥斯瓦尔多·克鲁兹基金会(Fiocruz)的血吸虫病转化计划(FioSchisto)的成员与受邀专家共同提出的,他们审查了世界卫生组织建议在巴西环境中的可行性,为适用于巴西流行病学现实的公共卫生政策提供了适当的建议,并提出了未来研究以解决相关问题。在巴西,提供安全用水和卫生设施应该是实现血吸虫病消除目标的关键行动。参与措施实施的机构应与初级保健团队一起行动,根据其流行病学指标,在优先市规划、执行、监测和评估行动。宿主蜗牛控制应优先考虑在繁殖地进行明智的生态干预。信息、教育和宣传(IEC)策略应与水和卫生设施及其他控制措施相结合,积极调动学校社区。为了识别受感染的携带者,FioSchisto 建议采用免疫和分子测试的两阶段方法,以在干预期间和之后验证传播中断。在初级保健层面,应在医疗监督下使用吡喹酮进行治疗。在特殊情况下,应考虑 MDA,作为在高流行地区的初始攻击策略的措施,始终与水和卫生设施、IEC 和蜗牛控制相结合。为了协助决策以及监测和评估战略行动,需要一个信息系统。FioSchisto 认为这种系统化对于投资于战略研究以支持改善血吸虫病控制行动至关重要。巴西的血吸虫病消除工作将取得成功,需要从垂直指令性框架转变为以社区为中心的方法,涉及跨部门和跨学科的合作。
