From: A small number of early introductions seeded widespread transmission of SARS-CoV-2 in Québec, Canada
A minority of introduction events are successful and spread across regions. A Distribution of Québec transmission lineage sizes, inferred using maximum likelihood ASR, n = 615. B Correlation between transmission lineage size and the number of Québec health regions in which it was sampled (Pearson’s r = 0.62, 95% CI = 0.57–0.67, p < 2.2 × 10−16). C Transmission lineage sizes generated by each PANGO lineage. Each point represents an independent introduction event into Québec. D Estimates of dN/dS for each PANGO lineage in Québec. For each PANGO lineage, the boxplots represent the distribution of dN/dS across sampled genomes compared to the ancestral reference genome (Wuhan-1; Genbank Accession MN908947.3)
