Abstract：
BACKGROUND: The World Health Organization recommends house-to-house case searches as an option to evidence whether the elimination of trachomatous trichiasis (TT) has been reached. We sought to determine the number of trachoma-endemic countries and districts that will require either documented full geographic coverage (DFGC) or TT-only surveys.
METHODS: We conducted a secondary analysis of data from the Trachoma Atlas to identify evaluation units (EUs) that require house-to-house case searches or TT-only surveys to demonstrate achievement of the elimination of TT.
RESULTS: There were 1710 EUs with TT above the elimination prevalence target in all trachoma-endemic countries. Of those EUs, 852 (49.8%) do not have a future survey planned and will therefore potentially have to evidence through DFGC or TT-only surveys whether the elimination prevalence target for TT has been reached.
CONCLUSIONS: Of the large number of EUs that require TT-related activities, nearly half of them will need to evidence that every household in the EU has been visited by a case finder and all confirmed cases managed. Given that this is a relatively new way to evidence elimination, and countries face different sociopolitical challenges, cross-country learning and improved guidance is key to support global elimination.

摘要：
背景：世界卫生组织建议进行逐户病例搜索，以证明是否已经消除了沙眼倒霉（TT）。我们试图确定沙眼流行国家和地区的数量，这些国家和地区需要记录在案的全地理覆盖（DFGC）或仅TT调查。
方法：我们对沙眼图集的数据进行了二次分析，以确定需要挨家挨户进行病例搜索或仅进行TT调查的评估单位（EU），以证明消除TT的成就。
结果：在所有沙眼流行国家中，有1710例患者的TT高于消除患病率目标。在这些欧盟中，852（49.8％）没有计划未来的调查，因此可能必须通过DFGC或仅TT调查来证明是否已达到TT的消除患病率目标。
结论：在大量需要TT相关活动的欧盟中，其中近一半将需要证据表明，欧盟的每个家庭都有一个病例发现者访问过，所有确诊病例都得到了管理。鉴于这是一种相对较新的证据消除方法，各国面临着不同的社会政治挑战，跨国学习和改进指导是支持全球消除的关键。
