Fig. 3

Geographic distribution of absolute numbers of SARS-CoV-2 sample sequences from the Pre-Omicron (a) and Post-Omicron (b) groups and the normalized distribution of sequences by Brazilian state per 100,000 inhabitants. In panel (a), the state of Acre (AC) is identified below the respective values, while in both panels (a) and (b), the state of Espirito Santo (ES) is labeled for clarity. The numbers represent the composition of the dataset selection based on the similarity of the sequences from Espirito Santo in the Post-Omicron group and do not reflect the actual number of sequences deposited in GISAID. (The maps were generated using Microsoft Excel 365 (Microsoft® Excel® for Microsoft 365 MSO, Version 2501 Build 16.0.18429.20132, 64-bit, www.microsoft.com) with built-in mapping features.).
