B Virus

The infection with the Hepatitis B virus (HBV) is a global health problem. Hepatitis B virus (HBV) infections are rapidly spreading in developing countries due to the lack of health education, poverty, illiteracy and Hepatitis B vaccination. No widespread population based data of HBV is available in the country's aspect. So, a population-based serological survey was done to determine the prevalence of the Hepatitis B core antibody total (IgM+IgG) in an impoverished Urban Community in Dhaka, Bangladesh. A descriptive cross-sectional study was conducted among 384 healthy individuals and age between 18-60 years from the urban slum in Dhaka city. The study was implemented through collaboration with Shaheed Suhrawardy Medical College, Dhaka from January 2013 to June 2013. The study participants were selected through systematic sampling procedure and blood tested for anti-HBc. Anti-HBc estimations were carried out by VITROS Immune diagnostic assay. The study was pertained Ethical permission from Bangladesh Medical Research Council (BMRC) and every participant was informed regarding their written informed consent. Among the 384 respondents, 183(47.6%) individuals were positive for the core antibody of hepatitis B virus (anti-HBc). The anti HBc positive group consisted almost of equal number of male 93, (24.2%) and female 90 (23.4%). There was a significantly increasing prevalence of the core antibody among young adults and middle age of the respondents (28.7%). Major risk factors for exposure to Hepatitis B appeared to be Ear-nose-body piercing, Circumcision by Hajam, unsafe blood transfusion and unsterile dental intervention. High prevalence of hepatitis B Core antibody (47.6%) indicates that the members of this urban community are highly exposed to hepatitis B virus.

INTRODUCTION: Viral hepatitis is an important public health problem in Brazil and around the world. OBJECTIVE: To evaluate vaccination coverage against hepatitis B in adolescents and to identify the associated factors and reasons for non-adherence. METHODS: A cross-sectional population-based study with sampling by clusters and in two stages, carried out from records of 702 adolescents aged 11 to 19 years old, non-institutionalized, living in an urban area of Campinas, São Paulo, Brazil, in 2008/2009. The data were obtained from the Health Survey in the city of Campinas (ISACamp). RESULTS: The prevalence of vaccination (3 doses) was 72.2%. An independent and negative association with the vaccine was observed for the adolescents who were not born in the municipality. The orientation of a health care provider was positively and significantly associated with vaccination. The main reasons for non-adherence were the lack of orientation and not considering the vaccine necessary. Socioeconomic factors, health behaviors and conditions did not restrict the access to vaccination, but the coverage was below the target established by the Ministry of Health in Brazil. CONCLUSION: Health education programs, addressing the importance of vaccination to prevent the disease; strategies to actively reach out adolescents that did not complete the schedule; as well as orientation from the health care professional about the benefits of the vaccine to the adolescents, parents and guardians can extend the vaccination coverage.

The Impact

Introduction: This study aimed to determine the seroprevalence of hepatitis B virus (HBV) infection in children and females in the middle Black Sea Region of Turkey and to assess the impact of the universal infant hepatitis B vaccination program started in 1998. Methodology: The laboratory records of 12,057 patients who attended the Samsun Maternity and Children’s Hospital between January 2007 and November 2009 were evaluated retrospectively. In this period, hepatitis B surface antigen (HBsAg), the antibody to hepatitis B surface antigen (anti-HBs), was studied from serum samples using the enzyme linked immunosorbent assay method. Results: In the total population, HBsAg seropositivity was found to be 3.8% (456/12010); anti-HBs was 32.6% (3526/10800). HBsAg was 3.5%, in the 0-14 year age group, 8.2% in the 15-18 group, 3.3% in the 19-49 group, and 8.0% in the over 49 group. The seropositivity of HBsAg decreased by half in patients between zero and 14 years of age (4.2%) who were included in the universal vaccination program when compared with those in the 15-18 year group (8.2%) who were not included in the program. There was a significant difference in HBsAg seropositivity between boys (5.8%) and girls (3.9%) (p < 0.05). Conclusions: According to the hepatitis B seroprevalence records of our region, HBsAg was 3.5% in the 0-14 year age group, 8.2% in the 15-18 year group. It may therefore be suggested that, since 1998, the vaccination program in our region has been successful.

The Impact

Background: Hepatitis B vaccine has been introduced in Nigeria for over a decade now, yet, data on sero-conversion status of the immunized cohort in the population are scarce. Such data are important for objective evaluation of the impact and effectiveness of the HBV vaccination program. This study therefore aims at determining the sero-conversion status and the prevalence of HBV infection among immunized cohort of children in Ekiti state, Nigeria. Methodology: This cross-sectional study was conducted across the three senatorial districts of Ekiti state, between October and December, 2017. A total of 441 children consisting of 226 males and 215 females (Male to female ratio= 1.1:1). Immunization was confirmed by immunization cards. Multistage sampling technique was used. Questionaire were administered after caregiver’s consent and assent from subjects, 2 to 5 mls of blood samples were then collected and tested for the various hepatitis B viral markers (HBeAg, HBeAb, HBcAb, HBsAb and HBsAg) using Hepatitis B combo kit manufactured by Innovita Biological Technology. Very low levels antibody titres which may not be detectable by qualitative detection method used is a limitation to this study. Results: Subjects were between 5 to 10 years. All subjects had 3 full doses of hepatitis B vaccination before the age of 1 year and all subjects were negative for HBsAg, HBeAg, HBeAB and HBcAb. However, only 47 (10.7%) had detectable HBsAb. Among HBsAb positive patients 22 were males while 25 were females. Our findings showed zero prevalence of hepatitis B but minimal seroconversion rate among vaccinated children in Ekiti state, Nigeria. Conclusion: Hepatitis B vaccination protects children against HBV in the study population. However, seroconversion rate showed that majority of the children may be at risk of HBV infection at a later age. We recommend a booster dose of HBV vaccination.

Detailed knowledge about hepatitis B virus (HBV) vaccination coverage and timeliness for sub-Saharan Africa is scarce. We used data from a community-based cross-sectional survey conducted in 2018–2019 in the area of Niakhar, Senegal, to estimate coverage, timeliness, and factors associated with non-adherence to the World Health Organisation-recommended vaccination schedules in children born in 2016 (year of the birth dose (BD) introduction in Senegal) and 2017–2018. Vaccination status was assessed from vaccination cards, surveillance data, and healthcare post vaccination records. Among 241 children with available data, for 2016 and 2017–2018, respectively, 31.0% and 66.8% received the BD within 24 h of birth (BD schedule), and 24.3% and 53.7% received the BD plus at least two pentavalent vaccine doses within the recommended timeframes (three-dose schedule). In logistic regression models, home birth, dry season birth, and birth in 2016 were all associated with non-adherence to the recommended BD and three-dose schedules. Living over three kilometres from the nearest healthcare post, being the firstborn, and living in an agriculturally poorer household were only associated with non-adherence to the three-dose schedule. The substantial proportion of children not vaccinated according to recommended schedules highlights the importance of considering vaccination timeliness when evaluating vaccination programme effectiveness. Outreach vaccination activities and incentives to bring children born at home to healthcare facilities within 24 h of birth, must be strengthened to improve timely HBV vaccination.
