Introduction Hepatitis B virus (HBV) infection is hyper-endemic in Nigeria. Prisons are high-risk environments for the spread of infectious diseases. Worldwide, seroprevalence of HBV infection is substantially higher among individuals in correctional facilities when compared to general population. We determined the seroprevalence and risk factors associated with HBV infection among Kuje prison inmates, Nigeria. Material and methods We conducted a prison facility based cross-sectional study. Interviewer administered questionnaires were used to obtain information on participants socio-demographic characteristics, HBV risk factors, previous HBV test and vaccination history. Blood samples collected from participants were analysed for HBsAg, HBsAb, HBcAb, HBeAg and HBeAb markers using rapid lateral chromatographic immunoassay kit. Univariate, bivariate, and multivariate analysis were performed. Results A total of 271 inmates (63 convicts and 208 awaiting trial inmates) were recruited into the study as participants. The mean age of the participants was 32.7 SD±9 years. HBV seroprevalence (HBsAg) of 13.7% (95% CI: 9.8–18.3) was found. 55.4% (95% CI: 49.2–61.4) of inmates were susceptible to HBV infection, 20.7% (95%CI; 16.0–26.0) had past HBV infection while 10.3% (95% CI: 7.0–14.6) had acquired natural or artificial HBV immunity. Factors found to be associated with current HBV infection (HBsAg) include age-group ≤25years (aOR = 8.0,95% CI: 2.9–22.3), being ever married (aOR = 4.2, 95% CI: 1.7–10.4) and history of alcohol consumption (aOR = 3.4, 95% CI: 1.3–8.4). Conclusion This study reveals a high seroprevalence of HBV infection among Kuje Prison inmates, hence the need to introduce prison-focused health intervention initiatives such as HBV screening, vaccination and care to reduce the transmission of HBV infection among inmates and ultimately the general population.

Abstract Background: Hepatitis B virus (HBV) infection is hyper-endemic in Nigeria. Prisons are high-risk environments for the spread of blood-borne and sexually transmitted infections. Prevalence of HBV infection is disproportionately higher among individuals in correctional facilities worldwide when compared to general population. We determined the seroprevalence and risk factors associated with HBV infection among Kuje prison inmates, Nigeria.Methods: We conducted a prison facility based cross-sectional study. Interviewer administered questionnaires were used to obtain information on participants socio-demographic characteristics, HBV risk factors, previous HBV test and vaccination history. Blood samples collected from participants were analysed for HBsAg, HBsAb, HBcAb, HBeAg and HBeAb markers using rapid lateral chromatographic immunoassay kit. Univariate, bivariate, and multivariate analysis were performed.Results: A total of 271 inmates (63 convicts and 208 awaiting trial inmates) were recruited into the study as participants. The mean age of the participants was 32.7 SD±9 years. HBV sero-prevalence of 13.7%(95%CI;9.8-18.3) was found. 55.4%(95%CI;49.2-61.4) of inmates were susceptible to HBV infection, 20.7% (95%CI;16.0-26.0) had past or resolved HBV infection while 10.3%(95%CI; 7.0-14.6) had acquired natural or artificial HBV immunity. Factors found to be associated with HBV infection include age-group ≤25years (aOR=8.0;95%CI:2.9-22.3), being ever married (aOR=4.2;95%CI:1.7-10.4) and history of alcohol consumption (aOR=3.4; 95%CI:1.3-8.4).Conclusion: This study reveals a high seroprevalence of HBV infection among Kuje Prison inmates, hence the need to introduce prison-focused health intervention initiatives such as HBV screening, vaccination and care to reduce the transmission of HBV infection among inmates and ultimately the general population.

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

Aims: The study was carried out among 120 dentists working in the selected hospitals of Dhaka city to find out the preventive practice on hepatitis B virus (HBV) infection. Methods: A descriptive type of cross-sectional study was carried out involving 120 dentists working in the selected hospitals of Dhaka city from December 2011 to March 2012 to quantify the preventive practice on HBV infection through a pretested semi-structured questionnaire. Results were analyzed by using the software SPSS 16.0 version (Chicago). Then analyzed data were presented according to the variables of the study showing percentage relationship between variables using appropriate statistical method.Results: Mean age of the dentists was 26.43±6.29 (range, 25-45) years where 74.17% were male and 25.83% were female. Among 120 respondents, 20.83% obtained BDS degree along with a postgraduate training (PGT) in any of the respective fields of dentistry. Others obtained MS in dentistry (21.67%), MPH in dentistry (10.83%), PhD in dentistry (9.17%), DDS in dental surgery (10%) and FCPS in dentistry (6.67%). Academic positions of the respondents were 33.33%, assistant professors, 26.67% associate professors, 19.17% medical officers, and 17.5% were lecturers. Majority (93.3%) dentists knew about HBV transmission, prevention, symptoms, risks, and concurrences. Out of them, 87.5% reported having been tested for HBV which was associated with their designations (p=0.013) and more than 75% reported having been vaccinated against HBV. Conclusions: A high level of knowledge and attitude towards practice in the prevention of HBV was found to be very good among the dentists of Dhaka city though seemed it was not always possible to take precaution for handling emergency patients. Further broad scale studies would be needed to have decisive results. DOI: http://dx.doi.org/10.3329/cdcj.v10i1.13831 City Dent. Coll. J Volume-10, Number-1, January-2013

INTRODUCTION: Vaccination is the main tool for preventing hepatitis B virus (HBV) infection; however, following the completion of the vaccination series, the concentrations of anti-HBs can decline over the years and reach levels less than 10mIU/mL. The persistence of protection in these individuals is still unknown. The present study aimed to determine the anti-HBs antibody levels among children and adolescents who had received a complete vaccination course for hepatitis B. METHODS: Antibodies against HBV surface antigen (anti-HBs) were tested in 371 individuals aged 10 to 15 years-old. RESULTS: Volunteers who showed undetectable quantities of anti-HBs accounted for 10.2% of the population studied and 39.9% presented antibody titers of less than 10mIU/mL. Anti-HBs ≥ 10mIU/mL were verified in 49.9%. CONCLUSIONS: These results corroborate other studies indicating levels of anti-HBs below 10mIU/mL in vaccinated individuals. Additional studies are required to assess whether this indicates susceptibility to HBV infection and the need and age for booster doses.
