Coronaviruses are a class of RNA viruses that can cause respiratory and intestinal infections in animals and humans. SARS‐CoV, MERS‐CoV, and a novel coronavirus (SARS‐CoV‐2 [2019‐nCoV]) belong to the family Coronaviridae and the genus Betacoronavirus. At present, the understanding of SARS‐CoV‐2 is getting deeper and deeper. In order to better prevent and treat SARS‐CoV‐2, this article compares the infectivity, pathogenicity, and related clinical characteristics of the three human pathogenic coronaviruses, SARS‐CoV‐2, SARS‐CoV, and MERS‐CoV to help us further understand the pathogenic characteristics of novel coronaviruses.

与新型冠状病毒SARS-CoV-2，SARS-CoV和MERS-CoV相关的病毒性肺炎的研究：文献综述。

冠状病毒是一类RNA病毒，可引起动物和人类的呼吸道和肠道感染。SARS-CoV，MERS-CoV和新型冠状病毒（SARS-CoV-2 [2019-nCoV]）属于冠状病毒科和Betacoronavirus属。目前，对SARS-CoV-2的理解越来越深入。为了更好地预防和治疗SARS-CoV-2，本文比较了三种人类致病冠状病毒SARS-CoV-2，SARS-CoV和MERS-CoV的传染性，致病性和相关的临床特征，以帮助我们进一步发展了解新型冠状病毒的致病特征。
