A new strain of coronavirus, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2, as named by the International Committee on Taxonomy of Viruses) discovered in Wuhan, China, in December 2019, has caused a global disruption and COVID-19 pandemic. SARS-CoV-2 is classified as Betacoronavirus. In general, coronavirus is the name of viruses that belong to the family Coronaviridae. These are classified into four categories: Alphacoronavirus, Betacoronavirus, Gammacoronavirus, and Deltacoronavirus. Alpha- and betacoronaviruses infect mammals, gammacoronaviruses infect avian species, and deltacoronaviruses infect both mammalian and avian species (Li, 2016). Coronaviruses are typically spherical, fatty enveloped viruses, which encapsulate large single-stranded RNA genomes, notably, the largest genome among all RNA viruses, typically ranging from 27 to 32 kb. The genome is packed inside a helical capsid formed by the nucleocapsid protein (N) and further surrounded by the envelope.
