Background: Hepatitis B Virus (HBV) infection has reached pandemic proportions all over the world with areas of highest prevalence being the sub- Saharan Africa and Southeast Asia. Most deaths related to HBV are due to complications from chronic infection. Acquisition of infection at a younger age is the most important predictor of chronicity. Eradication of HBV is an important but difficult tasks facing public health. HB immunization is the single most important factor in hepatitis B control and was commenced in 2004 in Nigeria.Objectives: To determine the prevalence of Hepatitis B surface antigen (HBsAg) among children in the era of HB immunization, the risk factors of transmission and knowledge of mothers about their HB status.Methods: A cross sectional study carried out on one hundred and forty children aged 18 months to 15 years at the children outpatient clinic (CHOP) of the University of Nigeria Teaching Hospital, Ituku. Hepatitis B surface antigen (HBsAg) was determined using Determine Test Kits and a structured interviewer administered questionnaire administered.Results: Six were positive for HBsAg, giving a prevalence rate of 4.3%. HBsAg was least prevalent among children 1-5 years (2%). None of the children ≤ 5 years who received HB vaccination was positive for HBsAg though one child > 5 years who received the vaccine was positive. Sharing of toothbrushes among siblings was found to be a significantly associated risk factor. Only 6.4% of mothers knew their hepatitis B status.Conclusion: There is a gradual fall in the prevalence of HBsAg in our environment due to HB immunization. Sharing of toothbrushes may be a potent means of transmission of HBV infection.Keywords: HBV, Prevalence, Children, Transmission, HB immunization

Infection due to Hepatitis B virus is a serious public health problem worldwide, in spite of productive vaccine. Pregnant women infected with hepatitis B virus can transmit the infection to their fetuses and newborns. The aim of the study was to determine the seroprevalence of Hepatitis B infection among pregnant women attending antenatal care at Specialist Hospital Yola. A total of three hundred and thirteen (313) pregnant women were randomly selected for this study. Hepatitis B status was determined by the presence of Hepatitis B surface antigen (HBsAg). A structured questionnaire was used for the data collection. Sera from volunteers were collected and tested for hepatitis B surface antigen. Seroprevalence was determined based on age group, educational level, occupation, marital status, religion and history of blood transfusion. The seroprevalence of HBsAg among consented antenatal attendees was 17(5.43%). The study found highest seroprevalence of HBsAg among the pregnant women in the age bracket 26-35 years 52.94%, 52.94% in women with primary school education, 41.18% among the unemployed, 94.12% among the married women, 70.59% among Muslim women, and 76.47% among women that had blood transfusion. The study also revealed that there is a significant relationship between HBsAg and (educational level, marital status) of the study participants (P < 0.05). The Seroprevalence of HBsAg among antenatal attendees at Specialist Hospital Yola, Nigeria, is on the high side. Therefore, early screening of pregnant women for hepatitis at antenatal clinic, would contribute greatly to the timely management of the disease and will prevent possible transmission to their neonates.

Abstract Background: Hepatitis B is a potentially life-threatening liver infection and a major global health problem. It causes chronic infection and puts people at high risk of death from cirrhosis and liver cancer. WHO estimated 257 million people are living with hepatitis B virus (HBV) infection and in 2015 alone HBV resulted in to 887,000 deaths globally. We determined the prevalence and associated factors of hepatitis B virus infection among Antenatal Care (ANC) attendees in Gamawa Local Government Area, Bauchi State. Methods: We conducted a descriptive cross-sectional, health facility-based study between March and April 2018. We used systematic random sampling technique to recruit 210 pregnant women aged 15-49 years. With a structured questionnaire, we interviewed the respondents and collected blood sample to test for hepatitis B surface antigen. We calculated frequencies, means, proportions, and tested for associations using Epi Info 7.2 and Microsoft Excel. Results: The mean age of respondents was 24.5 ± 6.0 years; 53.3% of whom were younger than 25 years. All were married, 87.1% had no formal education and up to 90.5% were employed. Overall, 6.7% tested positive for HBsAg; women aged ≥35 years had the highest prevalence (10.5%). None with tertiary education tested positive and women married before 18 years had 6.5% prevalence. Conclusions: The prevalence of HBsAg among pregnant women in Gamawa LGA was 6.7% which is quite lower than the national prevalence reported. We recommended improved surveillance of HBV infection and screening of women attending ANC.

Hepatitis B virus (HBV) continues to cause serious health problems in developing countries. Neonatal infection with HBV, which is often acquired during delivery, carries a high risk resulting in persistent infection. This research aims to detect the prevalence of Hepatitis B surface Antigen (HBsAg) among pregnant women in our location of study. One hundred and eighty (180) sera samples were screened among pregnant women aged 13-49, using standard enzyme-linked immunosorbent assay (ELISA) method. Structured questionnaire were administered to the subjects to obtain demographic and other relevant data. Overall result showed that 31 (17.2%) were found to be positive for HBsAg among the total subjects screened. The highest prevalence was found among those aged 20-29 with 11 (6.1%) seropositivity (x2=7.902; P=0.048). Considering occupational distribution of volunteer subjects, a high prevalence of 12 (6.7%); P&lt;0.05 was recorded among house wives, which shows a measure of significance compared to other women screened. Furthermore, based on various risk factors subjects with history of surgery and use of unsterilized sharp instruments recorded 15 (8.3%) prevalence (P=0.233; P&gt;0.05). How ever, women in their second trimester of pregnancy recorded a higher prevalence of 23 (12.8%):(P=0.080; P&lt;0.05). This study therefore emphasizes the public health importance of HBV among pregnant women and equally suggests that children born to women with Hepatitis B Virus, be closely monitored for infection beyond the one and the half years of age, this also calls for a proper enlightenment on the dangers posed by the virus, while a well designed vaccination schedule is advocated among the general population.
