Trachoma is the leading cause of infectious blindness worldwide. Though trachoma can be treated with antibiotics (active trachoma) or surgery (trachomatous trichiasis), it is still endemic in most parts of Ethiopia. Despite the prevalence of this infectious disease in different parts of the country, district level data is lacking. This study was thus conducted to assess the prevalence estimate of trachoma and its risk factors in Kersa District, Southwest Ethiopia.
A community based cross sectional Rapid Assessment of Trachoma was conducted using a WHO guideline. Six sub-districts were selected from Kersa District based on primary high risk assessment and from each sub-district; 21-27 households were randomly selected. Active trachoma for children aged 1-9 years, trachomatous trichiasis for people above 15 years old and environmental risk factors for trachoma were assessed. Data were analyzed using SPSS version 16.
The overall prevalence estimate of active trachoma was 25.2% (95% CI: 20.7-30.4%). Forty three percent of children had unclean faces, 11.5% of households had water source at more than half hour walking distance, 18.2% did not have functional latrine, and 95.3% of the households had solid waste disposal within a distance of 20 meters. Households with environmental risk factors were at an increased risk to active trachoma, but the association was not statistically significant (p>0.05). The prevalence estimate of trachomatous trichiasis inclusive of "trachoma suspects" was 4.5%.
Trachoma is endemic in Kersa District with active trachoma being a public health problem in the studied sub-districts. Hence, SAFE strategy should be implemented.
沙眼是全球传染性失明的主要原因。虽然沙眼可用抗生素治疗(活动性沙眼)或手术治疗(沙眼性倒睫),但在埃塞俄比亚大部分地区仍是地方病。尽管该国不同地区都有这种传染病流行,但缺乏地区层面的数据。因此,本研究旨在评估埃塞俄比亚西南部克萨区沙眼的患病率及其危险因素。
采用世界卫生组织指南进行基于社区的横断面沙眼快速评估。根据初步高风险评估从克萨区选取6个分区,从每个分区中随机选取21 - 27户家庭。评估1 - 9岁儿童的活动性沙眼、15岁以上人群的沙眼性倒睫以及沙眼的环境危险因素。使用SPSS 16版软件分析数据。
活动性沙眼的总体患病率估计为25.2%(95%置信区间:20.7 - 30.4%)。43%的儿童面部不清洁,11.5%的家庭水源距离超过半小时步行路程,18.2%没有可用厕所,95.3%的家庭在20米范围内进行固体废物处理。存在环境危险因素的家庭患活动性沙眼的风险增加,但这种关联无统计学意义(p>0.05)。包括“沙眼疑似病例”在内的沙眼性倒睫患病率估计为4.5%。
沙眼在克萨区呈地方病流行,在所研究的分区中活动性沙眼是一个公共卫生问题。因此,应实施SAFE策略。
