To validate the accuracy of previously published US seroprevalence estimates for hepatitis D virus (HDV) antibody, we retested National Health and Nutrition Examination Survey samples from 2007‒2018 using a different assay. We found the HDV seroprevalence among hepatitis B surface antigen positive participants aged ≥6 years to be 1.26%.
Casillas et al. (Wed,) studied this question.
