Phylogenetic analyses of HRV and HEV. This illustrates that recombination events are much more prevalent in the untranslated regions (UTRs) compared with a translated region (VP4/VP2). Separate alignments of the coding (VP4/VP2; 464 nt) and untranslated (5’UTR; 555 nt) regions’ sequences were constructed using MUSCLE v.3.8.31. Maximum likelihood phylogenetic trees were inferred separately for the non-coding and coding regions using PhyML v.3.0 using a general-reversible substitution model with gamma-distributed among-site rate variability. Samples are labeled by following format: “Sample code / Country of collection / Month- Year of collection.” Phylogenetic trees were colored by HRV species: HRV-A, HRV-B, HRV-C, and four types of HEV (HEV-A, HEV-B, HEV-C and HEV-D). In addition, four HRV-C clades show different recombination events and these are denoted individually as HRV-C.I to IV.
