SARS-CoV-2 is a betacoronavirus that belongs to the family Coronaviridae and the order Nidovirales [1]. Up to date, six coronavirus species have been identified to infect humans and cause disease. Among them, 229E, OC43, NL63, and HKU1 infections are frequently mild, mostly caused common cold symptoms [2]. The other two species, severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), might cause fatal illness [3]. SARS-CoV-2 is the seventh member of the coronaviruses that infects humans [4]. Infected patients predominantly presented with fever, cough, and radiological ground glass lung opacities, which resemble SARS-CoV and MERS-CoV infections [5].
