    Article - En anglais

    Hepatitis B surface antigen (HBsAg) was detected in 3.3% of 7162 pregnant Tunisian women tested and HBeAg in 9.6% of the HBsAg-positive mothers.

    Family members of 46 of these HBsAg-positive mothers (33 husbands and 61 children aged 1-6 years) were investigated) for the presence of HBV markers.

    HBsAg was detected in 21% of the children and 18% of the husbands.

    Fifty children born to HBsAg-positive mothers received hepatitis B vaccine at birth, at the age of 2-3 months and at the age of 9 months.

    After immunization, anti-HBs were detected in 92% of them with an anti-HBs geometric mean titre of 415 mIU ml-1.
