Phylodynamic analysis of region 1 in a curated study of echovirus 30 (E30) viral protein 1 (VP1) sequences from 22 countries in Europe, 2010–2018. We constructed the bootstrapped maximum likelihood neighbor-joining trees using 47 full length sequences and 277 VP1 sequences extracted from GenBank. E30 groups 1–8 are labeled. A) Maximum likelihood trees constructed by using MEGA version 7.0 (https://www.megasoftware.net). Prototype E30 strain Bastianni, (GenBank accession no. AF311938) was used as a reference. Scale bar indicates nucleotide substitutions per site. B) Maximum likelihood trees constructed by using Nextstrain (https://nextstrain.org) from which we dropped several problematic sequences, including group 5.
