Abstract: Recently discovered coronavirus causes coronavirus disease COVID-19 is a novel coronavirus with an outbreak of uncommon viral pneumonia which appeared in Wuhan, China and spread around the world.COVID-19is a single-stranded RNA viruses with a highly transmittable and pathogenic viral infection results in severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). COVID-19 belongs to genera Beta-coronavirus. There are more one kinds of human Beta-coronaviruses are;severe acute respiratory syndrome coronavirus (SARS-CoV or SARS-CoV-1), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID-19, andMiddle East respiratory syndrome (MERS)that are many similarities, but there is some differences in their genotypic and phenotypic structure that played critical roleintheir pathogenesis. As previously known that......
