[Virological characteristics of SARS-CoV-2 and COVID-19]

ABSTRACT

Summary The new coronavirus (SARS-CoV-2) is genetically similar to the SARS-CoV that emerged in 2003. SARS-CoV-2 is transmitted by the binding of its major antigen, the S protein, to the ACE2 receptor. In the case of SARS-CoV-2, the main antigen, S protein, binds to the ACE2 receptor. The development of vaccines and the clinical application of antiviral drugs are crucial for the control of COVID-19 infection in the future.
