Fig. 3From: A small number of early introductions seeded widespread transmission of SARS-CoV-2 in Québec, CanadaPhylogeny of SARS-CoV-2 genomes sampled from Québec in global context. A Pink dots on the time-scaled phylogeny show the most recent common ancestors (MRCA) of introduction events into Québec, inferred with ML ASR. Blue dots are all Québec sequences in the dataset. The heatmap shows Nextstrain clade designations for all sequences in the tree. B The same phylogeny, highlighting (blue branches) the eight Québec transmission lineages that gave rise to over 50 sequenced cases. Their introductions (large circles) are colored by their inferred region of origin. The colored heatmap shows the geographic origin of all sequences in the treeBack to article page
