To characterize viral hepatitis co-infections in a cohort of immigrants living in southern Italy. In a prospective multicenter study, all undocumented immigrants and low-income refugees consecutively evaluated for a clinical consultation at one of the five first-level clinical centers in southern Italy from January 2012 to February 2020 were enrolled. All subjects included in the study were screened for hepatitis B surface antigen (HBsAg), anti-hepatitis C virus (HCV) and anti-HIV; the HBsAg-positive were screened also for anti-delta.
