Objectives: To determine the prevalence of HBV, HCV and HIV in pregnant women and identify risk factors. Materials and Methods: Descriptive and analytical study on pregnant women in the community Maniema (DRC) between 24 June and 24 July 2013. We enrolled a total of 581 pregnant women. Results: Prevalence among pregnant women was 4.1% (2.5% to 6.3%) for HIV, 5.9% (3.9% to 8.4%) for the HBsAg and 4.1% (2.5% to 6.4%) for hepatitis C. The risk factor was for HIV, blood transfusion history in women. For HBsAg the main risk factor was the tattoo history and no statistically significant factor was found for hepatitis C. Conclusion: To reduce the risk of transmission of hepatitis from mother to child, all pregnant women should be screened prenatally. A strengthening of routine screening of blood products must be done and a health education of the population on the mode of contamination should be conducted.

Objectives: To determine the prevalence of HBV, HCV and HIV among children 6 to 59 months and determine the risk factors. Materials and Methods: Descriptive and analytical study on children aged 6 to 59 months of community Maniema (DRC) conducted between 24 June and 24 July 2013. We enrolled 781 children aged 6 to 59 months. For association between the presence of viral markers and potential risk factors the chi-square test of Pearson was applied, the odds ratios (OR) and their 95% confidence intervals (95% CIs) were calculated. The Fisher exact test was used when the conditions for application of the chi-square test of Pearson were not met. Results: The median age of the children was 34 months, 51% of female children. Ten percent of children had a history of blood transfusion; 6.6% and 64% had fever and anemia. The prevalence of HBsAg was 3.6%, the prevalence of antibodies against hepatitis C was 2.8% and HIV was 3.7%. The risk factors were HBsAg, male gender (5.5% male vs 2.0 % female; OR = 2.8(1.3 -6.9) p = 0.001) and urban areas (5.0% rural vs 0.5% urban, OR = 0.1 (0.01 -0.72), p = 0.01). For HCV and HIV, these factors were the history of blood transfusion in the child and the mother. For HCV 7.6% of children with blood transfusion history; OR = 3.2 (1.1 -8.5); p = 0.05 and 11.1% history's mother blood transfusion, OR = 5.6 (2.1 -14.1). For HIV 11.4% of children with blood transfusion history, OR = 3.8, p = 0.005 and 9.8% history's mother blood transfusion, OR = 2.9, p = 0.04. Conclusion: Vaccination against hepatitis B in children must be widespread, educational messages to the population must target the risk factors for these viruses. A screening of hepatitis in pregnant women must be J. M. Kabinda et al. 172coupled with rigorous selection policy for blood donors before each donation and qualification of any unit of blood.
