A) Maps showing virus movements inferred using continuous phylogeographic analysis for the fourth, sixth and seventh largest transmission lineages. Direction of movement is anti-clockwise, and dots are coloured by date. Cumulative number of UTLAs that the five largest Delta transmission lineages are sampled in absolute (B) and relative (C) time.
