目的：确定沙眼的患病率，并衡量SAFE战略（世界卫生组织2020年战略）在赞比亚南部格温贝地区治疗沙眼的影响。设计：这是一项采用协作方法的SAFE策略的引入及其对该地区沙眼的影响的观察性研究。参与者：本研究包括赞比亚南部格温贝地区26个井场社区的三千八百九十二人。方法：在所确定的26个村庄中，在当地监督下，每个村庄都打了新的清洁水井。居住在水井附近村庄的所有人都接受了沙眼筛查，然后在需要时接受抗生素治疗。由训练有素的志愿者提供个人和环境卫生教育。受倒睫和角膜瘢痕影响的患者在可能的情况下接受局部手术。采取了清理村庄、圈养牲畜和挖厕所等措施来控制苍蝇的数量。这是在当地村民和政府官员的指导和协商下进行的。收集了通常与沙眼有关的变量以及与人口统计、水质、环境和卫生有关的其他变量的数据。主要结果测量：在引进安全战略两年后该地区沙眼的患病率。结果：2001年该地区沙眼总患病率为47%；然而，10岁以下儿童的患病率为55%。干预后两年，沙眼的总体患病率降至7.6%，10岁以下儿童降至10.6%，成人降至5.9%。结论：为了维持在赞比亚这一地区的沙眼控制项目，需要继续处理持续监测和风险因素。
Purpose: To determine the prevalence of trachoma and to measure the impact of the SAFE strategy (World Health Organization GET 2020 strategy) for treating trachoma in the Gwembe District of Southern Zambia. Design: This is an observational study of the introduction of the SAFE strategy employing a collaborative approach and its impact on trachoma in the area. Participants: Three thousand eight hundred ninety two persons in communities at 26 well sites in the Gwembe district of Southern Zambia were included in this study. Methods: New, clean water wells were drilled under local supervision for each of 26 identified villages. All people living in villages near the wells were screened for trachoma and then treated with antibiotic if required. Education on personal and environmental hygiene was provided by trained volunteers. Patients affected by trichiasis and corneal scarring received surgery, locally if possible. Attempts to control fly populations by cleaning villages, penning livestock, and digging latrines were undertaken. This was performed under advisement and consultation with local villagers and government officials. Data was collected on variables normally associated with trachoma and others relating to demographics, water quality, environment and hygiene. Main Outcome Measures: Prevalence of trachoma in the area at two years post introduction of SAFE strategy. Results: The overall prevalence of trachoma in the area was 47% in 2001; however, the prevalence was 55% among children under 10 years. At two years post intervention, the overall prevalence of trachoma reduced to 7.6%, and decreased to 10.6% in children under 10 years, and 5.9% among adults. Conclusions: Continued monitoring and risk factors will need to continue to be addressed in order to sustain this trachoma control project in this area of Zambia.
