Maximum-likelihood phylogenetic inference of complete viral protein 1 nucleotide sequences of norovirus GII.17 Kawasaki. The tree was constructed using MEGA6 (http://www.megasoftware.net) (Technical Appendix). The red asterisk denotes the reference sequence of GII.17 Kawasaki virus (Hu/GII/JP/2015/GII.P17_GII.17/Kawasaki308; GenBank accession no. LC037415). The tree is rooted to genotype GII.21 (not shown for clarity). Bootstrap values >70 (percentage) are shown at nodes. Sublineages SL1 to SL3 are defined by the topology of haplotype network shown in Figure 2. Branches are colored by the continent of sequence origin. The tree is drawn in scale; scale bar indicates nucleotide substitutions per site.
