From: Sequential viral introductions and spread of BA.1 across Pakistan provinces during the Omicron wave
Evolutionary relatedness of the first reported Omicron variant from each region of Pakistan. A Phylogenetic tree for 944 Omicron genomes and related strains sharing the most recent common ancestor (MRCA). The first BA.1 sequence from each region, B Balochistan (purple); C Sindh (green); D AJK (light red); E Gilgit-Baltistan and KPK (yellow); F Punjab and ICT (light blue). Data are presented as Figtree v. 1.4.4 outputs using the maximum-likelihood tree generated using IQTREE v. 2.2.0. Grey triangles represent collapsed nodes of relatively distant sequences from the first Omicron sequences in each region. Scale bar presents nucleotide substitution/site
