Genetic relatedness between HEV strains from human and non-human sources and from various countries. Minimal spanning trees of 81 sequences of 148 nucleotides HEV RNA showing genetic distances between genotype 3 HEV strains from humans and animals. A: strains labeled by geographical origin. B: strains labeled by biological origin. The 13 recent Dutch cases are marked with ID numbers inside the colored circles.
