Phylogenetic tree of West Pomeranian SARS-CoV-2 sequences (n = 122) with an international context. Maximum likelihood tree of West Pomeranian SARS-CoV-2 sequences and a subset of BLAST sequences (n = 376) from GISAID database. Thirty countries of isolates’ origin have been identified. For eight countries that had a minimum of four (>1%) distinguished sequences, branches are colored. Multicolor rings correspond to the PANGO and Nextstrain virus classification. The blue, green, and orange triangles mark the node origins of the Clades 1–3.
