2020年全球消除致盲性沙眼联盟（GET2020）
The significant reduction in the global prevalence of trachoma has resulted from increased political will in endemic countries, expansion of control measures and generation of high-quality data.
In 1996, WHO launched GET2020, and with other partners in the Alliance, supports country implementation of the SAFE strategy and strengthening of national capacity for epidemiological assessment, monitoring, surveillance, project evaluation and resource mobilization.
