Co-infections with HIV and hepatitis B (HBV) and C (HCV) viruses are common, as these three viruses share common modes of transmission. HIV infection worsens the prognosis of HCV- and HBV-related liver disease. Since the use of potent antiretroviral combinations in HIV infection, patients’ life expectancy has increased. Morbidity and mortality related to HBV and HCV have therefore become key factors to consider in their management. In this context, and following the 2001 survey on HIV-HCV co-infection, a one-day cross-sectional survey on HIV and hepatitis B and C virus co-infections was conducted among individuals receiving care for HIV infection (HIV+) in short-stay healthcare facilities. Coordinated by the French Institute for Public Health Surveillance, the primary objective of this study was to estimate the prevalence of HIV-HBV, HIV-HCV, and HIV-HBV-HCV co-infections in this population. Secondary objectives included describing the demographic and epidemiological characteristics of HBV and HCV co-infections, estimating HBV vaccination coverage, and describing the diagnostic and therapeutic management of chronic hepatitis.
