Some protection against blood donations from HEV-infected persons may occur because HEV and malaria are coendemic to many countries. Our findings showed a higher HEV seroprevalence among donors with prior malaria or diarrhea deferrals; thus, malariaand diarrhea-related screening questions may reduce contributions from donors with travel-associated HEV infection. Our findings showed HEV exposure in travelers and nontravelers, suggesting the possibility of imported and locally acquired HEV in Australia. Prior HEV exposure was higher in donors who were temporarily excluded from donating blood on previous donation attempts, suggesting the current management strategy in Australia is partially effective in minimizing any risk of HEV transmission through blood transfusion. However, the presence of HEV IgG in donors who reported no overseas travel and/or no prior related deferrals, coupled with the knowledge that asymptomatic infection is possible, suggests that additional safety precautions may be warranted.
