摘　　要：根据现有的数据,新型冠状病毒(2019 novel coronavirus,2019-nCoV)比严重急性呼吸综合征冠状病毒(severe acute respiratory syndrome coronavirus,SARS-CoV)的传染性强、传播速度快、疫情规模大、病死率低。其传染性、传播速度和疫情规模似乎具有甲型流感病毒(influenza A virus)的特点。尽管2019-nCoV来源于何种动物尚无定论,但它与SARS-CoV同属冠状病毒,具有共同之处。如果流行过后2019-nCoV没能在人群中持续传播和存在(如同SARS-CoV一样),则控制野生动物传染源乃重中之重;如果2019-nCoV获得了能在人群中持续传播的能力,预防控制策略将与SARS-CoV明显不同,疫苗便成为至关重要的手段。Current observations demonstrated that comparing compared with severe acute respiratory syndrome coronavirus(SARS-CoV),the 2019 novel coronavirus(2019-nCoV)is more infectious judged by transmission rate,epidemic scale and lower mortality.Its human-to-human spreading power is similar to influenza virus.Although the animal origin of the 2019-nCoV is still not identified,it should have something in common with SARS-CoV,since both of them are members of coronavirus.If the 2019-nCoV could not persistently exist in the population,like SARS-CoV,the control of wild animal infectious sources should be the top priority.If 2019-nCoV could persistently exist in the population,the vaccination will become a crucial means for prevention and control of the disease.
