Phylogenetic tree obtained by Bayesian inference for all the RHDV strains analyzed. Numbers above branches indicate bootstrap values above 50 for ML analysis, and posterior probabilities above 0.80 for BI are shown below branches. Year and region of isolation is indicated for all samples. 95% HPD for the tMRCA of the main lineages found are indicated. Iberian clades within Lineage I are shown based on previous studies [24, 42] and new data. Names in italics indicate avirulent RHDV strains.
