The nCoV reported at present includes severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV) and recently discovered 2019 new coronavirus (2019-nCoV). nCoV is a new type of coronavirus. ncov can cause severe acute respiratory infection (SARI), acute respiratory distress syndrome, septic shock, renal failure and other critical disease states. It is urgent to improve the clinicians' understanding of the diagnosis and treatment of nCoV infection. To improve the ability of outpatient triage and early identification, to strengthen the prevention and control of nosocomial infection, to improve the comprehensive treatment ability of severe patients and to strengthen clinical research are the key to deal with the epidemic situation of nCoV infection.
