Neighbor-joining phylogenetic tree (TN93 evolutionary model) of human Puumala virus (PUUV) strains based on partial sequences of the S segment (504 nt, position 392–894). PUUV-sequence from strain Sotkamo was used as an outgroup. Sequences taken from GenBank are indicated by their accession numbers. The numbers 04 to 12 in front of the sample names indicate the year (2004–2012) when the sample was collected. Four sequences obtained in this study are colored in red (acc.-no.: KM013472-KM013475) and an additional sample (in blue) was published in an earlier study [Reference PMID: 22958255]. Phylogenetic clades are described earlier [Reference PMID: 22932394]. Scale bar indicates an evolutionary distance of 0.1 substitutions per position.
