Coronaviruses (CoVs) are enveloped positive sense, single-stranded RNA viruses that belong to the subfamily Coronavirinae, family Coronavirdiae, order Nidovirales. Four genera of CoVs, namely, Alphacoronavirus (αCoV), Betacoronavirus (βCoV), Deltacoronavirus (δCoV), and Gammacoronavirus (γCoV), are distinguished. This group of viruses is of zoonotic origin with αCoV and βCoV found in bats and rodents while δCoV and γCoV are found in avian …
