Fig. 4: Lineage B.1.106 phylogenetic tree and dispersion throughout KZN.

a, Phylogenetic tree of B.1.1.106 sequences by nosocomial outbreak (designated CH1 and CH3) and district location. b, Proportion of sequences classified as B.1.106 over time in KZN. c, Mapping the spread of the B.1.106 lineage from phylogeographic reconstructions. Time scale is specified in decimal dates from 2019.8 (October 2019) to 2020.5 (June 2020). Shade circular patterns represent confidence intervals of location estimation.
