(a) The distribution of SARS-CoV-2 lineages in Thailand from January to December 2024 includes each lineage along with its descendant lineages. (b) The variation frequencies over time are shown, where the size of each point indicates the weekly collection of sequences. These data points are assessed through logistic regression, with the shaded areas denoting the 95% confidence interval. Only the variants with the highest prevalence during the study period are displayed, emphasizing the most significant trends in variant distribution and their statistical reliability.
