Detection and characterization of hepatitis E virus genotype 3 in HIV-infected patients and blood donors from southern Brazil

Abstract

The prevalence rates of HEV infection were comparable between HIV-seropositive patients who were not severely immunocompromised and blood donors. The blood donor's HEV isolate showed high similarity with swine HEV strains from Brazilian herds in the same region, thus indicating a potential risk of foodborne and parenteral transmission via blood transfusion.
