Abstract

In Brazzaville (Congo), the prevalence of chronic carriage of HBs Ag (7.31%) we observed, is similar to the ones previously reported in 1981, 1982 and 1988. The sero-prevalence of anti-HBc is 67.21%. Anti-HBc are considered to be very relevant for the screening of VHB infection. Our study clearly points out that the highest prevalence of HBs Ag was observed among midwives. In all, the frequency distribution of the two serological markers we studied was similar in health workers and general population.

Abstract

Serum samples taken from 6,624 blood donors since 1984 to 1987, were tested for Hepatitis B virus surface antigen (HBs Ag) using a microhemagglutination assay and for anti-HIV antibodies by ELISA test. The mean carrier state of HBs Ag was 10.68% and that of anti-HIV antibodies was 6.99%. The association of HBs Ag and anti-HIV antibodies was discovered in 4.84% donors but without correlation for the period of the study.
