ojections of glycoproteins on its surface (diameter 80–120 nm).[1] Among all the RNA viruses, the RNA genome of CoV is one among the largest.[2] The number of open reading frames (ORFs) in the CoV genome ranges from six to ten.[2] CoV genetic material is susceptible for frequent recombination process, which can give rise to new strains with alteration in virulence.[3] There are seven strains of human CoVs, which include 229E, NL63, OC43, HKU1, Middle East respiratory syndrome (MERS)-CoV, severe acute r
