Fig. 3: Phylogenetic tree of the B.1.1.7 lineage from our samples and those sub-sampled globally.

From: Temporal lineage replacements and dominance of imported variants of concern during the COVID-19 pandemic in Kenya

The tree was constructed with 546 genomes, 381 from Kenya (182 from our study) and 165 sub-sampled from the globe. Genomes from other parts of the world include 44 genomes sampled from the earliest reported Alpha variants. The tree is rooted against the Wuhan/WHO1/2019 and Wuhan/Hu-1/2019 reference genomes (Genbank accession no. LR757998 and MN908947, respectively). The genomes from the study are shown in dark blue circular tips while other Kenyan genomes are shown in light blue circular tips. Genomes from other parts of the globe are shown in yellow circular tips. Kenyan samples branched from different parts of the tree, indicating multiple independent seeding events. Black arrows show samples from one of the first reported outbreak of the B.1.1.7 lineage in Kenya. Encircled red dots indicate earlier two independent introductions (18 January 2021) of the alpha variant outside the Nanyuki outbreak.
