Objectives Features of occult hepatitis B virus (HBV) infection among the anti‐hepatitis B core antigen (anti‐HBc) positives have yet to be described in more details. This study aimed to determine the molecular prevalence of occult HBV infection (OBI), and association to risk factors among seroposit...
