Fig. 1. A schematic of the follow-up data from the 17 blood donors who were positive for both the HEV antigen and RNA (n=17).

Among these 17 donors, 10 showed persistent viremia and/or antigenemia for ≥70 days after donation and increased anti-HEV IgG levels were observed in 3 donors. The other 7 donors showed negative conversion of pathogens (with both HEV antigen and RNA becoming negative) without a serologic response. Increasing IgG: increasing anti-HEV IgG level; Ag: HEV antigen
