Objective To investigate the prevalence of Hepatitis E virus (HEV) among blood donors in Wuhan urban agglomeration, aimed at providing data support for the development of HEV screening strategies for blood donors. Methods A total of 3 329 blood samples were collected from four centralized testing areas (Ezhou, Tianmen, Xiantao and Qianjiang) and screened at Wuhan Blood Center from January to December 2021. Among them, 2 737 were eligible blood samples with normal ALT (ALT normal group) and 592 were with elevated ALT (ALT elevated group). Enzyme linked immunosorbent assay (ELISA) was used to detect anti-HEV IgG, anti-HEV IgM and HEV-Ag, and Real-time PCR was used to perform single HEV RNA detection on blood samples with elevated ALT and normal ALT anti-HEV IgM+ blood samples. A two-sided Pearson’s chi-squared test or Fisher's exact test was used to evaluate the differences in the positive rates of anti-HEV IgG and anti-HEV IgM in different regions and ALT groups. Results The overall positive rates of anti-HEV IgG, anti-HEV IgM, and HEV-Ag in 3 329 blood samples from four regions were 21.63%, 1.29%, and 0%, respectively. There was a significant difference in the positive rates of anti-HEV IgG among blood donors in different regions (P
