Maximum likelihood analysis of Delta variant lineages with 4338 samples, numbers within with squares are aLRT branch support of respective clades. Black dots represent support ≥ 0.8. Colorful tips based on Brazilian regions and the 5 countries that presented the highest number of sequences recovered via blast. A. Complete tree. B. Weel supported subclades including Rio Grande do Sul samples. Bold sample lanes represent genomes sequenced in this study. Complete figure with branch support and uncollapsed clade is available on SupplementaryData7.
