Lineage and phylogenetic analysis.

(A) Phylogenetic tree of SARS-CoV-2 sequences representing global and Mozambique subsets during the first 25 months of the pandemic. Taxa obtained from Mozambique are illustrated with circles and the lines represent taxa from the global dataset. (B) Lineage through time plots illustrate the change in genetic diversity of sequenced genomes sampled in Mozambique throughout the study period.
