Trachoma is an eye disease caused by the bacterium Chlamydia trachomatis (Ct). It can lead to permanent vision loss. Since 2007, Burundi has included trachoma elimination as part of its fight against neglected tropical diseases and blindness. This study presents the results of trachoma baseline, impact and surveillance surveys conducted in Burundi between 2018 and 2021.
Areas were grouped into evaluation units (EU) with resident populations of between 100,000 and 250,000 people. Baseline surveys were conducted in 15 EUs, impact surveys in 2 EUs and surveillance surveys in 5 EUs; in each survey, 23 clusters of about 30 households were included. Consenting residents of those households were screened for clinical signs of trachoma. Access to water, sanitation and hygiene (WASH) was recorded.
A total of 63,800 individuals were examined. The prevalence of TF in 1-9-year-olds was above the elimination threshold of 5% in a single EU at baseline, but fell below the threshold in subsequent impact and surveillance surveys. The prevalence of TT was below the 0.2% elimination threshold in ≥15-year-olds in all EUs surveyed. A high proportion (83%) of households had access to safe drinking water, while only a minority (~8%) had access to improved latrines.
Burundi has demonstrated the prevalence levels necessary for trachoma elimination status. With continued effort and the maintenance of existing management plans, trachoma elimination in Burundi is within reach.
沙眼是一种由沙眼衣原体（Ct）细菌引起的眼部疾病。它可导致永久性视力丧失。自2007年以来，布隆迪已将消除沙眼作为其抗击被忽视热带病和失明工作的一部分。本研究展示了2018年至2021年期间在布隆迪进行的沙眼基线、影响和监测调查的结果。
将地区划分为评估单位（EU），每个评估单位的常住人口在10万至25万人之间。在15个评估单位进行了基线调查，在2个评估单位进行了影响调查，在5个评估单位进行了监测调查；每次调查纳入约30户家庭的23个群组。对这些家庭中同意参与的居民进行沙眼临床症状筛查。记录水、环境卫生和个人卫生（WASH）的获取情况。
共检查了63,800人。在基线时，1至9岁儿童中TF的患病率在单个评估单位高于5%的消除阈值，但在随后的影响和监测调查中降至阈值以下。在所有接受调查的评估单位中，≥15岁人群中TT的患病率低于0.2%的消除阈值。很大一部分（83%）家庭能够获得安全饮用水，而只有少数家庭（约8%）能够使用改良厕所。
布隆迪已达到消除沙眼所需的流行率水平。通过持续努力和维持现有管理计划，布隆迪消除沙眼指日可待。
