The aim of this study was to assess vaccination coverage against HBV in children in Brazzaville. Patients and Methods: This was a cross-sectional analytical study conducted in Brazzaville health centres from January to September 2019. It involved children aged between six months and six years who received a vaccination against HBV. Sampling was exhaustive and based on stratified sampling. Results: The overall prevalence of children vaccinated against HBV in Brazzaville was 96.2%. It was insufficient in the Talangai health district (79%). The pentavalent vaccine was administered to 97.7% of children, 85% of whom had received all three doses. The reasons for incomplete vaccination were parents’ ignorance of HVB (85.6%) and of vaccination (14.3%). Conclusion: Although the prevalence of vaccinated children is high in Brazzaville, it is still insufficient in some health districts, particularly Talangai, because parents are unaware of the disease and of vaccination. Pentavalent is the only vaccine available in the national vaccination programme, which is why an effective national vaccination policy needs to be put in place. .展开更多

Knowledge of transmission routes and prevention methods could play a key role in limiting and reducing the spread of the disease. Aim: This was a prospective study that was carried out from July 1 to September 30, 2018 in the department of gastroenterology and internal medicine in people carrying the hepatitis B virus. All patients were asked about their knowledge, attitudes and practices regarding viral hepatitis B. Materials and Methods: This was a cross-sectional study, collecting prospective data, which was carried out from July 1 to September 30, 2018 in the gastroenterology department of CHUB (University Hospital of Brazzaville). Eligible for the study were all patients who consulted or were followed in the ward for HBV infection during the study period. All patients were asked about their knowledge, attitudes and practices regarding viral hepatitis B. After obtaining informed consent, we asked patients about knowledge, attitudes and practices towards the hepatitis B virus. The data was collected on a pre-established survey sheet respecting anonymity and confidentiality. CSPro 7 software and SPSS 17 software were used for data entry and analysis. Chi-square was used to compare the percentages. These were expressed with their 95% confidence intervals [95% CI]. A value of p 0.005 was considered significant. Results: Forty-two patients were included in the study, these were 66.7% (n = 28) men and 33.3% (n = 14) women. The average age was 38.76 ± 10.9 years. 45.2% of them (n = 19) were single and 59.5% (n = 25) had the next highest level of education. Thirty-nine patients had no knowledge of the source of their contamination;the sexual route was the most cited (61.9%). Alcohol consumption was rated badly by 38 patients (90.5%);of these 22 (52.4%) thought it worsened the disease. Lack of knowledge of an HBV carrier in the family was noted in 33 (78.6%) patients;20 (47.6%) patients did not talk about their illness in th展开更多
