In this paper, the epidemiological and clinical characteristics of severe acute respiratory syndrome (SARS), pandemic (H1N1) 2009 and COVID-19 were compared. Compared with the other two diseases, COVID-19 is more contagious, more concealed in transmission, greater infectious intensity and more severe in clinical manifestations. If the COVID-19 epidemic was not effectively controlled, it would have a serious impact on human health and even social development. Understanding the characteristics of three diseases, especially COVID-19, and improving the awareness of the harmfulness of COVID-19 are of certain significance to the implementation of the guiding principle of "scientific prevention and treatment, precise implementation of strategies" and the prevention and control of COVID-19.
本文比较了严重急性呼吸综合征（SARS）、2009年甲型H1N1流感大流行和新型冠状病毒肺炎（COVID-19）的流行病学和临床特征。与其他两种疾病相比，新型冠状病毒肺炎传染性更强、传播更隐匿、感染强度更大且临床表现更严重。如果新型冠状病毒肺炎疫情得不到有效控制，将对人类健康乃至社会发展造成严重影响。了解这三种疾病的特征，尤其是新型冠状病毒肺炎的特征，并提高对新型冠状病毒肺炎危害性的认识，对于贯彻“科学防治、精准施策”的指导方针以及新型冠状病毒肺炎的防控具有一定意义。
