Genomic surveillance of SARS-CoV-2 variants by LabMovel. A-B. Frequency of SARS-CoV-2 variants in the tested population according to the position of LabMovel (for information about the prevalence of positive cases, see Fig. 3). C-D. Genomic characterization of SARS-CoV-2 variants of concern (VOCs; delta-gamma) circulating in the location where LabMovel was positioned. Time-stamped maximum likelihood (ML) phylogenetic tree, including the 820 newly sequenced isolates obtained in this study as well as a representative dataset obtained by subsampling containing 360 Brazilian gamma and delta strains and 258 worldwide obtained from GISAID (https://www.gisaid.org) as of September 2021. The sequences obtained in this study are presented as green (Baixada Santista) and red (Aparecida) dots. The delta VOCs obtained from the Baixada Santista region are randomly interspersed within the phylogenetic tree, while the ones from Aparecida do Norte form a monophyletic cluster (see the box)
