According to the genome analysis, 2019-nCoV belongs to Sarbecovirus subgenus, Betacoronavirus genus of the subfamily Orthocoronavirinae in the family Coronaviridae of the suborder cornidovirineae of the order Nidovirales [20,26]. Similarly to other coronaviruses, 2019-nCoV is an enveloped, single-stranded positive-sense RNA (+ssRNA) with around 29,900 nt, showing a typical coronavirus appearance under electron microscopy [20]. The genome organization is 5′-leader-UTR-replicase-S (Spike)-E (Envelope)-M (Membrane)-N (Nucleocapsid)-3′UTRpoly (A) tail with accessory genes interspersed within the structural genes and the 3′ end of the genome [26].
