Hepatitis E virus (HEV)-positive plasma donations, identified by a plasma mini-pool screening approach, were analysed using serological methods for the presence of anti-HEV IgM and IgG. Avidity testing was performed on the IgG-reactive donations. Anti-HEV IgG with high avidity was observed in two donors together with high viral loads, but with the absence of anti-HEV IgM. These data are suggestive of re-infection in a small proportion of plasma donors, which has not previously been reported.
