The study's aim is to evaluate the vaccination status against viral hepatitis B and the prevalence of HBs antigen in the medical staff of the University Hospital of Marrakech. This cross-sectional survey was conducted at the level of the various hospital services with the medical staff of Med VI University Hospital of Marrakech. A systematic search for the antigen /antibody pair level (Ag HBs/Ac antiHBs) and anti-nucleocapsid antibodies (Ac antiHBc) was performed in every person who participated in this study. A total of 172 doctors participated in the screening; the participation rate was 74%. 93% of the screened physicians were unaware of their serologic status with respect to the hepatitis B virus and 36% were not vaccinated against hepatitis B. The prevalence of HBsAg was 1.7% in our context with only one identified case of cure. As for the risk factors studied. In properly vaccinated doctors, 77% were immunized (≥100 IU / l) and this immunization rate was 8% in people who received 2 doses of vaccine. Health personnel constitute a population at risk for both infection and transmission of the Hepatitis B virus. Hence, raising staff awareness and introducing compulsory HBV vaccination for all health professionals is important.
