(A) Phylogenetic tree showing the evolution of SARS-CoV-2 from the initial origin China (2020/01/17). The tree represents the mutations or SNPs that resulted in the evolution of current SARS-CoV-2 in the last three months. Individual countries are colored in as shown in the color key. (B) Position and number of SNPs across are the genome is denoted with bar graph. (C) The key mutations with change in amino acid observed across the whole genome of 12 countries are listed and highlighted in red lines. Enlarged view showing the mutations occurred in spike glycoprotein. (D) Bar graph depicting the number of mutations and position is complete genome.
