Phylogenetic tree comparing the six Tunisian SARS-CoV-2 with 268 previously published sequences. The tree was performed using the neighbor joining method and the kimura-2 parameter model. Topology was supported by 1000 bootstrap replicates. For better clarity of the tree, lineages from the same country were collapsed and bootstrap values lower than 50 were not indicated (a). Phylogenetic clusters including SARS-CoV-2 Tunisian genome sequences were detailed in (b to g). The sequences reported in this study are shown in red bold, and indicated by the accession number, laboratory code, district, country code, week and year of isolation. The sequences downloaded from GISAID and NCBI database are indicated by their accession number followed by the country code and the year of isolation
