a Stacked bar chart showing the chronological distribution of lineages for IMSSC2 samples (n = 4595). Colors represent the Delta (B.1.617.2) variant, including all its sublineages, and Omicron sublineages, including recombinants that emerged over the observation period. The solid line indicates the total count of samples sequenced within the IMSSC2 laboratory network on a weekly basis. The stacked bar plot was created in R (version 4.2.2) using the ggplot2 library (version 3.4.0). b Mutational profiles of SARS-CoV-2 sublineages illustrating mutation patterns in the spike protein of the respective Omicron sublineages, based on a minimal mutation prevalence of 75%, according to outbreak.info.org. c Map of Germany representing the geographic distribution of IMSSC2 network laboratories (highlighted in yellow) according to population density. The map is adapted from https://www.deutschlandatlas.bund.de/DE/Karten/Wo-wir-leben/006-Bevoelkerungsdichte.htmld Phylogenetic analysis of German SARS-CoV-2 genomes identified by the IMSSC2 laboratory network. The phylogenetic tree, colored according to Pangolin lineage assignment and with branch length representing genetic divergence, is based on sequences randomly collected (n = 4,595).
