^* Data shown are from blood donors with the exception of those marked *, which are from healthy adults. HEV RNA was genotype 3 in all cases, except where stated.

¹ Deconstructed solvent–detergent treated mini–pools.

² Only 1,939 donors tested.

³ Of those with HEV viraemia, 57% were genotype1 and 43% genotype4.
