The purpose of these surveys was to determine the prevalence of trachomatous inflammation-follicular (TF) in children aged 1-9 years and trichiasis prevalence in persons aged ≥15 years, in 13 Local Government Areas (LGAs) of Taraba State, Nigeria.
The surveys followed Global Trachoma Mapping Project (GTMP) protocols. Twenty-five households were selected from each of 25 clusters in each LGA, using two-stage cluster sampling providing probability of selection proportional to cluster size. Survey teams examined all the residents of selected households aged ≥1 year for the clinical signs TF, trachomatous inflammation-intense (TI) and trichiasis.
The prevalence of TF in children aged 1-9 years in the 13 LGAs ranged from 0.0-5.0%; Ussa LGA had the highest prevalence of 5% (95%CI: 3.4-7.2). Trichiasis prevalence ranged from 0.0-0.8%; seven LGAs had trichiasis prevalences above the threshold for elimination. The backlog of trichiasis in the 13 LGAs (estimated combined population 1,959,375) was 3,185 people. There is need to perform surgery for at least 1,835 people to attain a trichiasis prevalence in each LGA of <0.2% in persons aged ≥15 years. In six of the 13 LGAs, 80% of households could access washing water within 1 km of the household, but only one LGA had >80% of households with access to improved latrines.
One of 13 LGAs requires antibiotic mass drug administration for active trachoma. Community-based trichiasis surgery needs to be provided in seven LGAs. There is a need to increase household-level access to improved washing water and latrines across the State.
这些调查旨在确定尼日利亚塔拉巴州13个地方政府辖区内1至9岁儿童沙眼性炎症-滤泡型（TF）的患病率以及15岁及以上人群倒睫的患病率。
调查遵循全球沙眼地图绘制项目（GTMP）的方案。每个地方政府辖区通过两阶段整群抽样从25个群组中各选取25户家庭，抽样概率与群组规模成正比。调查团队检查了所选家庭中所有年龄≥1岁居民的TF、沙眼性炎症-重度（TI）和倒睫等临床体征。
13个地方政府辖区内1至9岁儿童的TF患病率在0.0%至5.0%之间；乌萨地方政府辖区患病率最高，为5%（95%置信区间：3.4 - 7.2）。倒睫患病率在0.0%至0.8%之间；7个地方政府辖区的倒睫患病率高于消除阈值。13个地方政府辖区（估计总人口为1,959,375）的倒睫积压人数为3,185人。需要为至少1,835人实施手术，以使每个地方政府辖区内15岁及以上人群的倒睫患病率低于0.2%。在13个地方政府辖区中的6个，80%的家庭能够在距家1公里范围内获取洗涤用水，但只有1个地方政府辖区有超过80%的家庭能够使用改良厕所。
13个地方政府辖区中有1个需要进行抗生素群体给药以治疗活动性沙眼。需要在7个地方政府辖区提供基于社区的倒睫手术。有必要在全州范围内增加家庭层面获取改良洗涤用水和厕所的机会。
