Extended Data Fig. 1. Spatiotemporal expansion of the SARS-CoV-2 Gamma variant across Brazil.
SARS-CoV-2 genome sequences were obtained from the GISAID repository23 along with confirmed lineage assignments. The frequency of the Gamma variant (dots) in weekly SARS-CoV-2 genome sequence counts (size of dots) is shown along with posterior median estimates of Gamma’s variant frequencies (black line) under the Bayesian multi-strain fatality model and 95% credible intervals (grey ribbon).
