To establish that trachoma is a public health problem in Burundi, and to provide baseline data on the prevalence of active trachoma and unclean faces prior to the commencement of trachoma elimination activities in endemic districts.
For each of 11 pilot districts, eight collines (hills) (estimated population generally 1000-8000) were selected at random using a population-proportional-to-size technique; from each selected colline, one sous-colline (of which there are generally 3-5 per colline) was selected at random by simple random draw. In each selected sous-colline, all available 1-9-year-old children were examined for clinical signs of trachoma, and for signs of an unclean face (defined as eye discharge, nose discharge and/or presence of one or more flies on the face during the time taken to examine the eyes).
A mean of 230 children were examined per sous-colline (range 44-600); in all, 20,659 children were examined in 90 sous-collines of 11 districts. (In one district, 10 rather than eight sous-collines were selected.) In three contiguous districts (Buhiga, Nyabikere and Muyinga) in the country's north-east, the prevalence of the sign "trachomatous inflammation-follicular" (TF) in 1-9-year-olds was >10%. In nine districts, the prevalence of unclean faces was >10%.
Trachoma is a public health problem in Burundi. Implementation of trachoma control activities is indicated in at least Buhiga, Nyabikere and Muyinga. Further work should be carried out to establish the likely backlog of unoperated trachomatous trichiasis.
确定沙眼在布隆迪是一个公共卫生问题，并在流行地区开展沙眼消除活动之前，提供关于活动性沙眼患病率和面部不清洁情况的基线数据。
对于11个试点地区中的每个地区，采用按人口规模比例抽样技术随机选择8个山丘（估计人口一般为1000 - 8000）；从每个选定的山丘中，通过简单随机抽样随机选择1个小山丘（每个山丘一般有3 - 5个小山丘）。在每个选定的小山丘中，对所有1 - 9岁的儿童进行沙眼临床体征检查，以及面部不清洁体征检查（定义为在检查眼睛期间眼睛有分泌物、鼻子有分泌物和/或面部有一只或多只苍蝇）。
每个小山丘平均检查230名儿童（范围为44 - 600）；总共在11个地区的90个小山丘中检查了20659名儿童。（在一个地区，选择了10个而不是8个小山丘。）在该国东北部的三个相邻地区（布希加、尼亚比凯尔和穆因加），1 - 9岁儿童中“沙眼性炎症 - 滤泡型”（TF）体征的患病率>10%。在9个地区，面部不清洁的患病率>10%。
沙眼在布隆迪是一个公共卫生问题。至少在布希加、尼亚比凯尔和穆因加应开展沙眼控制活动。应进一步开展工作，以确定未经手术治疗的沙眼性倒睫可能的积压情况。
