In the recent two decades, three global viral infectious diseases, severe acute respiratory syndrome (SARS), middle east respiratory syndrome (MERS), and coronavirus disease (COVID-19), have occurred worldwide. SARS occurred in November 2002, causing 8096 infected cases, as well as 774 deaths. MERS occurred in June, 2012, causing 2519 confirmed cases, along with 866 associated deaths. COVID-19 occurred in December 2019, as of 30 April 2020, a total of 3,024,059 clinical cases have been reported, including 208,112 deaths. Healthcare workers (HCWs) need to be in close contact with these virus-infected patients and their contaminated environments at work, thus leading to be infected in some of them, even a few of them are died in line of duty. In this review, we summarized the infection status of HCWs during the outbreak of SARS, MERS and COVID-19, with in-depth discussion, hoping to provoke sufficient attention to the HCWs infection status by more people.

在最近的二十年中，全球已发生三种全球病毒感染性疾病，即严重急性呼吸道综合症（SARS），中东呼吸综合症（MERS）和冠状病毒病（COVID-19）。SARS发生于2002年11月，造成8096例感染病例，造成774人死亡。中东呼吸综合征于2012年6月发生，造成2519例确诊病例以及866例相关死亡。COVID-19于2019年12月发生，截至2020年4月30日，已报告了3,024,059例临床病例，包括208,112例死亡。医护人员（HCW）需要在工作中与这些感​​染了病毒的患者及其受污染的环境保持密切联系，从而导致其中一些人被感染，甚至其中一些人因公死亡。在这篇评论中，我们总结了SARS，MERS和COVID-19爆发期间HCW的感染状况，
