Coronavirus is an RNA virus consisting of positive-sense single-stranded RNA of approximately 27–32 kb. Coronavirus belong to the family Coronaviridae, which comprises of alpha, beta, delta, and gamma coronaviruses [1,2]. As the name indicates, the spherical external spike protein displays a characteristic crown shape when observed under an electron microscope [3,4]. The virus is known to infect a wide range of hosts including humans, other mammals, and birds. Infected hosts exhibit different clinical courses, ranging from asymptomatic to severe symptoms in their respiratory, digestive, and genital organs [1,2]. There are 6 known coronaviruses that typically cause infection in humans. Among these, coronavirus 229E, OC43, NL63, and HKU1 generally cause mild cold-like symptoms, whereas severe acute respiratory syndrome-coronavirus (SARS-CoV) in 2003, and Middle East respiratory syndrome-coronavirus (MERS-CoV) in 2012, caused severe respiratory diseases such as pneumonia and death [5,6].
