Thus both the host body or internal environment and the external environment performs equally as a source, responsible for shaping the genetic evolution of the SARS-CoV-2 towards theCOVID-19 disease fitness in nature in a pandemic form. The probable line of development for such pandemic outcomes happened by continuous evolutionary procedure within different species or host environment exposure, by mutation during replication or genetic recombination between two different viral species and ultimate adaptation to a susceptible host by natural selection of the new version of the viable pathogen resulting infection [7, 8] . Then genetically close different subtypes of SARS-CoV-2 develops unique spike protein receptor binding domain with high degree of receptor binding property to human cells and adapt itself to fit the character inside the host body.	./cache/cord-292657-gq3965se.txt	./txt/cord-292657-gq3965se.txt
