Figure 1. Phylogenetic analysis of 1st Bangladeshi SARS-CoV-2 complete genome sequences retrieved in this study, with available complete sequences from different countries (n=33 genome sequences). GISAID: Global Initiative on Sharing All Influenza Data; HKY: Hasegawa, Kishino, and Yano; MEGA 7: Molecular Evolutionary Genetics Analysis across Computing Platforms; SARS-CoV-2: severe acute respiratory syndrome coronavirus. Main clusters are highlighted in blue colors. The Wuhan reference genome is in navy color marked as reference sequence (GenBank accession number: NC_045512.2). The scale bar at the bottom of the tree represents 0.000050 nt substitutions per site. The cluster containing the viral sequence of the 1stBangladeshi SARS-Cov-2 genome sequence (GISAID accession ID: EPI_ISL_437912) is in red. The viral genome sequence from all other countries are divided in to fide clade marked as Cluster A to Cluster E. tree was built by using the best fitting substitution model (HKY) through MEGA 7 software.
