BACKGROUND Trachoma is a contagious infection of the eye by specific strains of the bacteria Chlamydia trachomatis. It is the leading cause of blindness worldwide. Mass drug administration (MDA) with azithromycin is a cornerstone of World Health Organization (WHO)'s global effort to eliminate trachoma by 2020. This coverage survey was aimed to assess trachoma post-mass drug administration (MDA) coverage among six selected districts of East Wollega, Horo Guduru Wollega, and West Shewa zones in2017. METHODS A community based cross-sectional coverage survey was conducted. The sample size was calculated automatically using Coverage Survey Builder (CSB) tool in microsoft excel. Thirty segments were selected per each selected districts of the three zones. A separate Results Entry Form for each district surveyed was completed, saved and uploaded directly into the online Coverage Survey Analysis Tool to estimate the surveycoverage and the program reach along with the corresponding 95% confidence limits and design effects. EPI-INFO 7.0 and SPSS version 20 was used for further analysis of survey data. RESULT A total of 1,747 households were surveyed, out of which 10,700 individuals were interviewed. Most respondents (95.1%) stated that they heard about trachoma MDA and most of them replied that they got the information from health workers. Program reach ranged between 89.5% in Jimma Geneti district and 94.8% in Dirre Hinchini district. The most common mentioned reasons for not having taken azithromycin included not knowing about the campaign, fear of side effects and being absent during the MDA campaign. CONCLUSION In this survey, four of the six districts met the target threshold (i.e. 80%) for effective coverage; Ambo rural and Jimma Geneti did not meet the target threshold.Therefore, programmatic improvements should be made for the future campaign to reach the expected thresholds while the campaign in four of the six districts should be encouraged.

2017年，埃塞俄比亚西部奥罗米亚六个区的沙眼大规模药物管理（MDA）后的覆盖范围评估调查。

背景技术沙眼是由沙眼衣原体细菌的特定菌株引起的眼睛的传染性感染。它是全世界失明的主要原因。含阿奇霉素的大规模药物管理（MDA）是世界卫生组织（WHO）到2020年在全球消除沙眼的全球努力的基石。这项覆盖率调查旨在评估在六个选定地区中沙眼的大剂量药物管理（MDA）覆盖率。 2017年的东Wollega，Horo Guduru Wollega和West Shewa地区。方法进行了基于社区的横断面覆盖率调查。样本大小是使用Microsoft Excel中的Coverage Survey Builder（CSB）工具自动计算的。在三个区域的每个选定区域中选择了30个细分市场。为每个接受调查的地区填写了一个单独的“结果输入表”，保存并直接上传到在线Coverage Survey Analysis工具中，以估计调查覆盖率和计划的覆盖范围以及相应的95％置信度限制和设计效果。EPI-INFO 7.0和SPSS版本20用于进一步分析调查数据。结果总共调查了1,747户家庭，其中有10,700人接受了采访。大多数受访者（95.1％）表示他们听说过沙眼MDA，并且大多数人回答说他们从卫生工作者那里得到了信息。吉马吉内蒂区的计划普及率在89.5％之间，而迪尔·欣奇尼区的计划普及率在94.8％之间。未服用阿奇霉素的最常见原因包括对运动不了解，担心副作用以及在MDA运动中缺席。结论在本调查中，六个区中有四个达到有效覆盖的目标阈值（即80％）；安博乡村和吉马·吉内蒂（Jimma Geneti）没有达到目标阈值，因此应在计划上进行改进，以使未来的运动达到预期的阈值，同时应鼓励在六个地区中的四个地区进行运动。
