Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a new virus from the coronavirus family (1) regarded as enveloped, positive-sense, single-stranded ribonucleic acid (RNA) viruses with helical symmetric nucleocapsid (2). According to the whole genome sequencing and phylogenetic analysis of coronavirus strains, a distinct clade of betacoronavirus is shown to be associated with severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (3). This novel clade is called the 2019 novel coronavirus (2019-nCoV) and due to more similarity to the SARS virus is also called severe acute respiratory syndrome coronavirus 2. The disease is known as COVID-19.
