    Abstract:
    AIM: To evaluate knowledge and perception of hepatitis B, including prevention, among Moroccan health care workers (HCWs) and to estimate seroprevalence of hepatitis B and vaccine coverage (VC). METHODS: Four hundred and twenty HCWs were randomly selected and stratified by site: 120 in Rabat, 140 in Taza and 160 in Témara-Skhirat. The study included an anonymous questionnaire about knowledge of hepatitis B and its prevention and a serological survey. Oral statements and vaccine registers were used to analyse the VC of the HCWs. Serological testing and VC were analysed according to the occupational exposure. RESULTS: Participation rates in the questionnaire and serological tests were 68% (285/420) and 66% (276/420), respectively. Fifteen (5%) HCWs had a history of hepatitis B. All HCWs considered that hepatitis B virus (HBV) infection may be acquired through blood exposure. Vaccination was acknowledged as a necessary means against HBV transmission by 276 (98%) HCWs. Forty-two per cent HCWs had no HBV serological markers. The prevalence of hepatitis B surface antigen was 1%. The mean prevalence of hepatitis B core antibody (anti-HBc) was 28% and was significantly higher (P < 0.05) among nursing auxiliaries (57%), nurses (30%), medical physicians (31%) and midwives (25%) than among laboratory technicians (13%). According to the vaccination registers (available in two sites), VC (> or =3 doses) was 55%. VC was 75% among midwives, 61% among nurses, 53% among nursing auxiliaries and 38% among medical staff. Of the fully vaccinated HCWs without anti-HBc, 51% had serological evidence of protection. CONCLUSION: HBV vaccines should be more readily available for Moroccan HCWs by reinforcing current vaccination programmes.
