Letter to the EditorHepatitis E virus in hematopoietic stem cell donors: Towards a systematic HEV screening of donors?

- Hepatitis E virus could be transmitted through hematopoietic stem cell products.
- We report the first study about HEV prevalence among hematopoietic stem cell donors.
- The rate of HEV seroprevalence in donors was 9% (13% in adult donors).
- HEV seroprevalence increased to 18% in donors originating from South France.
- Anti-HEV IgM and HEV RNA were not detected in any donor.
