Fig. 7. Relative Re of SARS-CoV-2 VOCs in Amazonas.
a Observed and estimated frequencies of SARS-CoV-2 variants in the Amazonas state. Circles, triangles, and plus signs represent weekly observed frequencies of Gamma, Delta, and Omicron BA-1, respectively. Red, blue, and orange solid lines are estimated average frequencies of Gamma, Delta, and Omicron, respectively, and paled-colored areas represent their 95% confidence intervals. b The estimated average relative Re of SARS-CoV-2 infections with respect to Delta. Solid lines represent the maximum likelihood estimates, and dotted lines represent their 95% confidence intervals (CI). c Temporal variation in the Re of major SARS-CoV-2 clades circulating in Manaus, estimated using the BDSKY approach. The estimates’ median (solid lines) and 95% HPD intervals (shaded areas) are represented.
