The northern Ghana Upper East Region [UER], Upper West Region [UWR], and Northern Region (NR) lie within the African trachoma belt. The 3 regions share common features of poverty, dryness, dusty environments, and poor environmental hygiene. Trachoma has been identified previously in the NR and the UWR as a disease of public health importance and a control program is underway.
To establish baseline prevalence and risk factor parameters in the Upper East for possible control of trachoma in the region.
Population-based cross-sectional survey using multi-staged cluster sampling techniques was used. In all 26,323 participants from 4,374 households in 160 communities were examined with a 2.5x magnifying binocular loupe for trachoma; 7,763 were children aged 1-9 years and 15,191 were aged 15 years and over.
Only 3 children were identified with active trachoma (trachoma with follicles, TF = 1; trachoma with intense inflammation, TI = 2) giving regional prevalence of 0.01% (Confidence Limits, CL: 0.0-0.1) for TF and 0.03% (CL: 0.0-0.1) for TI. Trachomatous trichiasis was measured at 0.05% (CL: 0.0-0.1) while children with clean faces was measured at 95.5%. Only 3.6% of the examined households in the region had access to a toilet facility.
Trachoma is not a disease of public health importance in the UER of Ghana despite being in a trachoma endemic zone and sharing the necessary risk factors for the disease.
加纳北部的上东部地区(UER)、上西部地区(UWR)和北部地区(NR)位于非洲沙眼带内。这三个地区具有贫困、干燥、多尘环境和环境卫生差等共同特征。沙眼先前已在NR和UWR被确认为具有公共卫生重要性的疾病,并且正在实施一项控制计划。
确定上东部地区沙眼的基线患病率和风险因素参数,以便在该地区对沙眼进行可能的控制。
采用多阶段整群抽样技术进行基于人群的横断面调查。使用2.5倍放大双筒放大镜对来自160个社区4374户家庭的26323名参与者进行沙眼检查;其中7763名是1-9岁的儿童,15191名年龄在15岁及以上。
仅发现3名儿童患有活动性沙眼(有滤泡性沙眼,TF = 1;有严重炎症性沙眼,TI = 2),TF的地区患病率为0.01%(置信区间,CL:0.0 - 0.1),TI的患病率为0.03%(CL:0.0 - 0.1)。沙眼性倒睫的测量患病率为0.05%(CL:0.0 - 0.1),面部清洁的儿童比例为95.5%。该地区接受检查的家庭中只有3.6%有厕所设施。
尽管加纳上东部地区处于沙眼流行区且具备该疾病的必要风险因素,但沙眼并非该地区具有公共卫生重要性的疾病。
