ABSTRACT
In order to assess the importance of mother-child transmission of the hepatitis B virus (HBV) in the Tunisian Sahel, 81 HBsAg-positive mothers have been selected at delivery in a representative sample of 1940 who delivered in maternities of this region. Each HBsAg-positive mother was matched for age and parity particularly with two HBsAg-negative mothers. Children born to these 66 HBsAg+ and 120 HBsAg- mothers were traced at 28 months and tested by ELISA for HBV serologic markers (HBsAg, anti-HBs and anti-HBc). The distribution of these markers was significantly different according to the maternal status for HBsAg. The overall prevalence rate of HBV markers was higher in children born to HBsAg+ mothers as compared to children born to HBsAg- mothers (33.3% vs 13.3%, OR = 2.5, 95% CI1.4-4.2). For HBsAg, the figures were 27.3% and 9.2% respectively (OR = 2.9, 95% CI 1.5-5.9). Given the prevalence rate of HBsAg in mothers (4.2%), the role of mother-child transmission in the spread of HBV infection and the intensity and precocity of horizontal transmission, systemic vaccination against HBV at birth should be recommended in the Tunisian Sahel in the context of the EPI. However this decision should take into account, in terms of cost/efficacy ratio, the other public health problems concerning this area.
