From: A small number of early introductions seeded widespread transmission of SARS-CoV-2 in Québec, Canada
Introduction and duration of the 12 largest Québec transmission lineages each responsible for 40 or more sequenced cases. Left: Timelines are colored by the health region in which each Québec transmission lineage predominantly spread, and which SARS-CoV-2 lineage (Pangolin nomenclature) was responsible. Squares represent the date the lineage was first sampled, colored by their inferred origin. Open circles show the median TMRCA of each transmission lineage, with whiskers showing HPD 95% intervals estimated with BEAST. Right: median and HPD 95% interval of the effective reproductive number, Re, for each transmission lineage, estimated using BEAST (Methods). These transmission lineages were inferred by ML ASR. See Figure S2 for TMRCA estimates for the 21 largest transmission lineages, represented by at least 20 sequences
