Tremendous progress has been made towards the goal of global elimination of lymphatic filariasis (LF) transmission by 2020. The number of endemic countries reducing LF transmission through mass drug administration continues to increase, and therefore, the need for effective post-intervention surveillance also continues to increase. Togo is the first sub-Saharan African country to implement LF surveillance, and it has 6 years of experience with this passive surveillance system. We herein report the results of a recent evaluation of the Togolese LF surveillance system, including an evaluation of blood donors as a surveillance population, and provide updated results of ongoing surveillance, including expansion in remote areas. Since implementation of LF surveillance in 2006, only three cases of positive Wuchereria bancrofti filaremia have been detected, suggesting that interruption of transmission has been sustained. Given the impracticality of validating the surveillance system in the absence of ongoing transmission, we confirmed the lack of transmission through a nationwide reassessment survey.
在 2020 年实现全球消除淋巴丝虫病（LF）传播的目标方面取得了巨大进展。通过大规模药物治疗来减少 LF 传播的流行国家数量不断增加，因此，对有效干预后监测的需求也在不断增加。多哥是第一个在撒哈拉以南非洲实施 LF 监测的国家，并且已经有 6 年的被动监测系统经验。我们在此报告了对多哥 LF 监测系统的最新评估结果，包括对献血者作为监测人群的评估，并提供了正在进行的监测的最新结果，包括在偏远地区的扩展。自 2006 年实施 LF 监测以来，仅检测到 3 例阳性班氏丝虫血症，表明传播已被阻断。鉴于在没有持续传播的情况下验证监测系统的不切实际性，我们通过全国范围的重新评估调查确认了没有传播的情况。
