Distribution of mutation frequency across the viral genome in our cohort of 249 COVID-19 patients. (A) Sample distribution for patients infected with Delta and Omicron variant, categorised based on their clinical outcomes - recovered and mortality. (B) Mutational landscape for all the four subgroups, depicting the cohort frequency of mutations according to its genome coordinates. (C) Intersection of mutations between the subgroups – Delta mortality, Omicron mortality, Omicron recovered and Delta recovered. (D) Visual representation of gene normalisation for both the VOCs, wherein the number of mutations were normalised with respect to the length of the gene.
