沙眼的流行现状及防治的研究进展

Research progress of the epidemic situation and the prevention and control of trachom a

沙眼是由沙眼衣原体感染所致的一种传染性角结膜炎,目前在世界57个国家流行。1998年世界卫生组织(World Health Organization,WHO)将2020年全球消灭致盲性沙眼(global alliance to eliminate blinding trachoma by 2020,GET2020)列为其防盲工作的主要目标之一。世界卫生组织制定了辨认和命名沙眼的简化分级系统及以社区干预为基础的防治沙眼的SAFE策略,此后10余年各国对此策略进行了不断推广、执行,目前世界上沙眼的流行趋势较之此前有了一定的变化,我国也启动了"计划2016年前在中国根治致盲性沙眼"的防盲工作。本文就SAFE策略推广以来沙眼诊断、治疗及流行趋势等方面的进展做一综述。

Trachoma, a contagious keratoconjunctivitis （ KC ） , caused by Chlamydia trachomatis infection, is rife in 57 countries in the world at present. The World Health Organization （ WHO） listed the global alliance to eliminate blinding trachoma by 2020 as one of top priorities of its blindness prevention in 1998. A simplified classification system for identifying and naming trachoma, designated by WHO, and the SAFE strategy based on community intervention were extended continuously in the world in 10 years since then. The trachoma prevalence trend has showed a change compared with that in the past. China has launched the blindness prevention action, aimed to eliminate blinding trachoma by 2016. In this paper, we reviews progress in diagnosis, treatment and epidemic of trachoma since the extension of the SAFE strategy.
