中东呼吸综合征（MERS）是一种由新型冠状病毒引起的病毒性呼吸道疾病。截至2015年7月17日，世界卫生组织（WHO）通报全球共报告1 368例确诊病例，其中至少490例死亡，病死率达35.82%。自2015年5月20日确诊首例病例至7月19日，韩国累计报告186例，其中1例输入至我国。鉴于我国与中东地区及韩国有持续的人员往来，不排除再次发生输入性病例的可能。本文就MERS疫情进展、防控应对等进行阐述。

Middle East respiratory syndrome (MERS) is a viral respiratory disease caused by a novel coronavirus. The first case of MERS was reported in Saudi Arabia in 2012. As of 17 July 2015, 1 368 laboratory-confirmed cases (490 deaths; mortality 35.82%) have been reported to World Health Organization (WHO). Since the first case reported on 20 May 2015, and as of 19 July, Republic of Korea has reported 186 confirmed MERS cases, including one case exported to China. Considering the continuous personnel exchanges between China and the Middle East Area, Republic of Korea, the possibility cannot be ruled out that imported MERS cases could emerge again in China. This review elaborates the epidemic characteristics and strategies of prevention and control of MERS.
