Background: According to the WHO report, Ethiopia is regarded as a country with intermediate to hyperendemic viral hepatitis infections, though it has no national strategy for surveillance, prevention and control of viral hepatitis. Without intervention, a mother who is positive for HBsAg and HBeAg has as high as 90% risk of passing the infection to her offspring. Therefore, this study tried to assess the seroprevalence and associated factors of HBV infection among pregnant women attending antenatal care in public health facilities of Dire-Dawa, Eastern Ethiopia. Materials and methods: A facility based cross-sectional study was conducted from January to March 2018 among 334 pregnant mothers. After obtaining a consent forms, data were collected by face to face interview and blood samples were collected to test for HBsAg. Logistic regression analysis was employed to identify factors significantly associated with HBV infection. A p value <0.05 was considered as level of significance. Results: The mean age of participated pregnant mothers was 24.93 years (+2 SD 5.21). The prevalence of HBV infection found to be 8.4% in the study area. On multivariate analysis, being single pregnant mothers (p-0.002), having nose/ear pierce (p-0.018), history of blood transfusion (p-0.008), circumcision (p-0.004), and HIV coinfection (p-0.032)} were factors significantly associated with HBV infection. Conclusion: To halt spread of this virus, increasing awareness on modes of transmission should be considered. Screening all pregnant women for HBV should be made as part of routine antenatal care service. Interventions should be targeted on reduction of circumcision by all concerned bodies.

Hepatitis B virus (HBV) infection remains a global health problem. With about 380 million chronic carriers of the HBV virus, there are over two million global deaths annually. Ghana is among the high endemic countries in Africa, with HBV prevalence ranging from 4.8% to 12.3% in the general population, 10.8% to 12.7% in blood donors and about 10.6% in antenatal clinic (ANC) attendees. The main objectives of this study were to test how socioeconomic factors, risky behaviors, knowledge and awareness of HBV infection correlate with actual HBV status among antenatal clinic attendees and to determine the predictors of HBV testing among ANC attendees. The study employed random sampling technique to sample 500 pregnant women, at mothers' clinic of Volta Regional Hospital, Ho, Ghana. A structured questionnaire was used to collect information on socio-demographic characteristics, Hepatitis B status, possible risk factors, awareness and knowledge levels of HBV infection. Cross tabulation and the chi-square (χ 2) statistic were used to determine statistical independence or association of study variables. Kruskal-Wallis test was applied to test for the differences in HBV knowledge scores across HBV status and levels of HBV awareness; and the binomial regression model was used to determine the predictors of HBV testing among ANC attendees. It is evident that age, religion, ethnicity, educational level, blood transfusion, number of blood transfusions, gravidity, parity, awareness of HBV and monthly income were associated with HBV status. Results of the Binomial Logistic Regression model indicate that Age (p = 0.03), Education level (p = 0.04), Religion (p = 0.04), Ethnicity (p = 0.00) and Blood transfusion (p = 0.04) were significant (p < 0.05) predictors of HBV testing. Knowledge of HBV status enables patients to seek early treatment, facilitates referral for social support and coun

Background: Hepatitis B virus infection is one of the serious public health problems in the world particularly in a developing country. It is transmitted from person to person by anybody fluid commonly through sexual intercourse. Hepatitis B virus infection has serious effects on both pregnant women and infants. Objective: This study aims to assess the magnitude of Hepatitis B virus infection and associated factors among pregnant women attending antenatal care service in Bishoftu town. Methods: A cross-sectional study was conducted involving a total of 276 pregnant women attending antenatal care service at Bishoftu town from July 17-August 17, 2019. A systematic random sampling technique was used to select the study subjects. A blood sample was drawn from each study subject to testing for Hepatitis B surface antigen and confirmation for positive results was done by an enzyme-linked immune sorbent assay. Completed data from questionnaires were entered into Epi info version 7 and, exported and analyzed by SPSS Version 21. Descriptive statistics were carried out to estimate the characteristics of the participants. Bivariate and multivariate logistic regression analyses were used to identify factors associated with Hepatitis B virus infection. Odds ratios at 95% confidence interval were calculated. P-value < 0.05 was considered as a significant. Result: The magnitude of Hepatitis B virus infection among pregnant women attending antenatal care services in Bishoftu town was 18 (6.5%). Study subject with the previous history of the dental procedure [AOR=4.79, 95%CI (1.41-16.23)], body tattooing [AOR=3.18, 95%CI (1.01-10.03)] and those with a multi-sexual partner [AOR=5.19, 95%CI (1.09-24.60)] were known to have a significant association with Hepatitis B virus infection. Conclusion and Recommendation: This study indicates that Bishoftu town has intermediate endemicity of Hepatitis B virus infection among pregnant women. Regarding the risk factors, pregnant women with a dental procedure, body tattooing, and multi-sexual partner were found to be at risk of Hepatitis B virus infection. To minimize the higher risk exposure status of mothers, increasing awareness and public health education on the mode of Hepatitis B virus transmission, high-risk behaviors and methods of prevention are recommended.
Background: Hepatitis B infection is among the most common public health concerns globally, particularly in low-and middle-income countries. The prevalence of hepatitis B infection is more common among most vulnerable populations, including pregnant women. However, there are limited studies on hepatitis B virus infection among pregnant women in low-income countries, including Ethiopia, and the previous studies focused on the general population rather than the pregnant women. The purpose of this study was to estimate the prevalence and examine factors associated with hepatitis B virus infection among pregnant women in the Northern Ethiopia. Methods: nstitution-based cross-sectional study design and a structured face-to-face interview were used to collect data from the study participants. Simple random sampling method was used to select eligible study participants. Data were entered using EpiData version 3.1, and SPSS version 20 was used for the data analysis. We analyzed the data to examine factors associated with hepatitis B virus infection using binary and multivariable logistic regression models. Results: The overall prevalence of hepatitis B virus infection among the study participants was 9.2%. The majority (46.7%) of the study participants infected by hepatitis B were in the age group 25-34 years. The study found that married study participants were more likely to be infected by hepatitis B when compared to the unmarried study participants. Having history of abortion [OR = 0.12 (95% CI: 0.03, 0.47), P < 0.01] and having history of tattooing [OR = 0.21 (95% CI: 0.07, 0.62), P < 0.01] were found to be statistically significantly associated with the prevalence of hepatitis B virus infection among pregnant women. Conclusion: A significant number of pregnant women participating in the study were infected by the hepatitis B virus which needs efficient intervention to reduce the infection rate. Further, educational status, having history of surgery, dental procedure, ear piercing, abortion and tattooing were found statistically to be significant before controlling for confounders. But, after controlling for confounders, only having history of tattooing and having history of abortion were found to be independent factors affecting the prevalence of the infection.

Infections due to viral hepatitis are systemic diseases caused by viruses A-E that mostly involve the liver. [1] It is a DNA virus which belongs to the family Hepadnaviridae. The virus was first discovered as 'Australian antigen' and later named hepatitis B surface antigen (HBsAg) in the blood of patients. Hepatitis B e antigen (HBeAg) was discovered later as a marker for patients at a high risk for transmission of the disease. [2] Infection caused by hepatitis B virus (HBV) is a serious public health problem causing about two billion infections worldwide. [3] Transmission is commonly through blood transfusion, blood products, body fluids (urine, semen, sweat, saliva, and tears), use of contaminated needles, vertical transmission (mother to child through infected birth canal), and sexual contact. [1] Neonates born of chronically infected mothers have a 70-90% risk of the infection progressing to a chronic phase. [3] Most countries in Africa have a high HBV endemicity, with the exception of Morocco and Tunisia, which have intermediate endemicity. [4] A prevalence rate of 10% of HBV was found among pregnant women in Hong Kong, [3] 12% in Taiwan, [5] and17.3% in Burkina Faso. [6] A b s t r A c t Background: Pregnant women infected with hepatitis B virus (HBV) can transmit the infection to their fetuses and newborns. Neonates who contract the HBV have about 90% risk of developing chronic HBsAg carriage (HBsAg: hepatitis B surface antigen) and chronic liver disease. Neonatal immunization interrupts this vertical and perinatal transmission. Objectives: To determine the seroprevalence of HBsAg among pregnant women attending the antenatal clinic at Aminu Kano Teaching Hospital (AKTH) and to identify potential risk factors associated with HBV infection. Materials and Methods: A case control study was conducted involving a total of 303 pregnant women attending the antenatal clinic at AKTH and 303 nonpregnant women of childbearing age. Blood sample was collected from each woman and the serum tested for the presence of HBsAg using latex rapid agglutination slide test kit (Cal-Tech Diagnostic Inc., USA) in the laboratory of the hospital. Reactive samples were stored at-20ºC and further confirmed for HBsAg using enzyme-linked immunosorbent assay (ELISA) kits (Bio-Rad, France). HBsAg-positive samples were tested for hepatitis B e antigen (HBeAg) using ELISA kits (Orgenics, Israel). A pretested, structured questionnaire was used for the collection of sociodemographic data and possible risk factors. Results: The prevalence of HBsAg among pregnant women and nonpregnant women were 7.9 and 7.6%, respectively. There was no statistically significant difference in the prevalence of HBsAg in pregnant and nonpregnant women. The presence of HBeAg was statistically significant among both pregnant and nonpregnant women who tested positive for HBsAg. The risk factors associated with HBV infection were blood transfusion, ear piercing, history of an affected sibling with HBV infection, tattooing, and abortion among pregnant women. Conclusion: The prevalence of HBsAg in this study was not statistically different in pregnant and nonpregnant women. There was a high level of HBeAg infection among pregnant women who tested positive for HBsAg. History of an affected sibling with HBV infection, tattoo, and abortion were significant risk factors for HBV infection.
Background: Hepatitis B is a global public health problem and a major cause of liver disease, including chronic hepatitis, cirrhosis and liver cancer. Pregnant women with hepatitis B virus infection are reservoir for the virus and do have high potential to transmit it to their fetuses and newborns. The objective of the study was to investigatesero-prevalence of hepatitis B surface antigen and assesses risk factors among pregnant women in Ethiopia. Methods: Institution based cross-sectional study was conducted from July to September, 2014 among pregnant women in Ethiopia. A pretested structured questionnaire was employed to collect data on socio-demographic and potential risk factors for HBV infection. Blood sample was collected and tested for the presence of hepatitis B surface antigen using Enzyme Linked Immunosorbent Assay kit. Obtained data were evaluated by frequency, logistic regression analyses, and a significance level of 5 % (α = 0.05) was established. Result: Of the total pregnant women, 11(5.4%) of the study participants were positive for HBsAg. Majority (40.1%) of participants were in age group 25-29 years. The prevalence of HBV infection was higher above 20 years of age. Our finding revealed that none of the study participants were aware of their HBV sero-status. Sero positivity for hepatitis B surface antigen was statistically associated with history of abortion (AOR: 6; 95% CI :(1.39-27.69); P-value: 0.017), surgery (AOR: 5;95% CI: 1.04-24.31; P-value: 0.045) and family history for hepatitis (AOR: 11; 95% CI (1.63 80.44); P-value: 0.014). Conclusion: According to the research findings, there was an intermediate endemicity of hepatitis B virus infection. The finding revealed that history of abortion, surgery and family history for hepatitis were the major risk factors for the high prevalence of hepatitis B infection in the study area. Appropriate, targeted and timely response is mandatory for tackling the harmful health effects of HBV infection/disease.
Background: Hepatitis B virus (HBV) infection is one of the most common public health problems worldwide. Over one million people die annually of HBV- related chronic liver disease. HBV during pregnancy has high rate of vertical transmission and adverse effect on both the mother and child. Data on seroprevalence and associated factors among pregnant women in Dubti or surrounding is scarce. Objective: To assess the prevalence and factors associated with HBV among pregnant women attending antenatal care (ANC) clinic in Dubti Hospital, Methods: Institution based cross-sectional study design will be conducted from Dec. 15, 2017 to Jan. 15, 2018 G.C on 307 pregnant women. All pregnant mothers who come for ANC during the study period who fulfill the inclusion criteria will be interviewed using a structured and pre tested questionnaire by face to face interview to assess socio-demographic and explanatory variables. Venous blood sample will be taken and Hepatitis B surface antigen (HBsAg) will be detected using an enzyme linked immunosorbent assay (ELISA) or rapid Test diagnosis (RDT). After the data collection, data from all the questionnaires will be coded, entered and cleaned to check for completeness, outliers and missed values and variables using Epi Info version 3.5.1. Data will be cleaned and coded using Epi and fed into SPSS version 20 for analysis. Finally data will be exported to SPSS package version 20 for further analysis. Logistic regression was employed with 95% CI and p value of <0.05 was used as statistically significant. Budget: The project requires a cost of 28,070 Ethiopian Birr.

Background: Epidemiological data on hepatitis B virus (HBV) infection among pregnant women in Cameroon are very scarce, especially in the rural milieu. The purpose of this study was to determine the prevalence and factors associated with HBV infection, and the infectivity of rural pregnant women in the Far North Region of Cameroon. Methods: A cross-sectional study was conducted in three rural health facilities of the Guidiguis health district between December 2013 and March 2014. We consecutively recruited 325 pregnant women attending antenatal consultations. A pretested questionnaire was used to collect socio-demographic data and factors associated with HBV infection. The presence of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and human immunodeficiency virus (HIV) were determined using commercial test strips. Regression analyses were used to assess correlates of HBV infection. Results: The mean age was 24.4 (SD5.6) years. Most women were married (97.2%) and housewives (96.4%), with less than secondary education level (80%). Only 4 women (1.2%) had been vaccinated against HBV. Thirty-three women (10.2%) were HBsAg-positive, of whom 4 (12.1%) were positive to HBeAg. The prevalence of HIV infection was 2.5% (8/325). Overall, 5 (1.5%) women were co-infected with HIV and HBV. Independent correlates of HBV infection included history of blood transfusion (adjusted odd ratio 12.59, 95% CI 1.46-108.89; p = 0.021) and concurrent infection by HIV (adjusted odd ratio 22.53, 95% CI 4.76-106.71; p < 0.0001). Conclusion: The prevalence of HBV infection among pregnant women in this rural milieu is high. History of blood transfusion and HIV infection are highly associated with HBV infection. The relative low rate of women positive to both HBsAg and HBeAg suggests that perinatal transmission of HBV might not be the prevailing mode of HBV transmission in this area.
Background: Hepatitis B infection is one of the world's most serious public health problems, causing significant morbidity and mortality. More than 2 billion individuals around the world have been infected with the hepatitis B virus (HBV), and approximately 400 million people are chronically infected with the virus, with more than a million dying each year from hepatitis B virus-related liver disease. A newborn infant whose mother is positive for both HBsAg and HBeAg has a 90% chance of developing chronic infection by the age of 6. Its infectivity is a 100 times that of the human immunodeficiency virus, but it receives little attention in public health. Therefore, this study was conducted to assess the prevalence of hepatitis B infection and its associated factors among pregnant mothers attending antenatal care at public hospitals in west Hararghe, eastern Ethiopia 2020. Method: This institution-based cross-sectional study was conducted on 300 pregnant mothers selected by systematic random sampling from September to December 2020. Data were collected by face-to-face interview using a pretested structured questionnaire. A blood sample was collected and tested for hepatitis B surface antigen using the enzyme-linked immunosorbent assay test method. Data were entered into EpiData version 3.1 and exported to Statistical Package for the Social Science version 22 for analysis. Bivariate and multivariable logistic regressions were used to assess the association between outcome and predictor variables. P-value <0.05 was considered to be statistically significant. Results: The overall seroprevalence of hepatitis B virus infection was 8% [95% confidence interval (CI): 5.3-11.0] among pregnant mothers. History of tonsillectomy [adjusted odd ratio (AOR) = 5.7; 95% CI: 1.3-23.9], tattoo (AOR = 4.3; 95% CI: 1.1, 17.0), having multiple sexual partners (AOR = 10.8; 95% CI: 2.5, 45.9), and history of contact with jaundiced patients (AOR = 5.6; 95% CI: 1.2, 25.7) were factors associated with the seroprevalence of hepatitis B virus infection among pregnant mothers.

Hepatitis B virus (HBV) when transmitted vertically can be severe on neonates and life threatening. Among others, risk factors for HBV include unprotected sex, needle-stick injuries and blood transfusion. The study was conducted to determine the seroprevalence of HBV markers and associated risk factors among one hundred and sixty consenting pregnant women attending some hospitals in Kano, Nigeria. Using enzymelinked immunoassay, sera were screened for HBV sero-markers and structured questionnaires were administered to obtain sociodemographic data and possible predisposing factors to HBV infection. Of the five HBV markers known, participants tested positive for four, which include HBsAg, HBsAb, HBeAb and HBcAb. All were seronegative for HBeAg. Ninety three percent (93.1%) tested positive for at least one HBV marker and 6.9% were seronegative for all markers. Among those that tested positive for HBsAg, 54.5% (p=0.33) were housewives, 36.4% (p=0.53) had only primary school education, 72.7% (p=0.14) were middle-class, none had previous knowledge of HBV infection and its mode of transmission, 54.5% (p=0.14) regularly shares sharp objects, 45.5% (p=0.37) had ear or nose piercing, and 9.1% (p=0.01) regularly shares towel and underwear. A large percentage of the study group had history of the infection while only 1.3% of the subjects were vaccinated. Sociodemographic background of the participants, low vaccination coverage and certain risk factors like the sharing of unsterilized sharp objects seem to aid the moderately high prevalence of HBV in this study. The study also revealed that the risk of mother-to-child HBV transmission is low in the study area and that incomplete vaccination may not confer artificial immunity against HBV infection.
