However, this recent study [2] did not explore the association between genetic variation in SARS-CoV-2 and the severity of COVID-19. Therefore, it is an urgent need to explore the association of the mutation pattern of SARS-CoV-2 genome with the severity and fatality of COVID-19. Based on the above discussion, we hypothesize that the genetic variation in SARS-CoV-2 may explain variable severity of COVID-19 in the population. Analysis of sequencing data of SARS-CoV-2 genome showed evidence of mutation at the beginning of the worldwide spread of COVID-19 [1] . This hypothesis can be tested by obtaining genetic sequences of SARS-CoV-2 from two groups of COVID-19 patients.	./cache/cord-344170-qrupbtem.txt	./txt/cord-344170-qrupbtem.txt
