The clinical characteristics and the epidemiological criteria for COVID-19 patients were described. Still, the risk factors for mortality and a clear course of the disease clinically, including viral shedding, have not been identified. Corona Virus and its Types: Coronaviruses are a group of viruses belonging to the Coronaviridae family which infect animals as well as humans.

Furthermore, the betaCoV genus divides into five sub-genera or lineages.
