Hepatitis B, C and Delta Viruses’ Infections and Correlate Factors Among Female Sex Workers in Burkina Faso, West-Africa

Seroprevalence of Hepatitis B Virus, Hepatitis C Virus, Syphilis and Associated Factors Among Female Sex Workers in Gondar Town, Northwest Ethiopia

Background

Sexually transmitted infections (STIs) are a public health problem worldwide. Hepatitis B virus infection (HBV), hepatitis C virus infection (HCV), and syphilis are among the STIs. Female sex workers (FSWs) continue to be a high-risk group for STIs due to a variety of factors, including exposure to unsafe sexual practices. Therefore, this study determines the seroprevalence of HBV, HCV, Treponema palladium, and associated factors among FSWs in Gondar town, Northwest Ethiopia.

Methods

A cross-sectional study was conducted on 194 FSWs from March to June 2021 in Gondar town. Socio-demographic and behavioral data were collected using a questionnaire. Five milliliters (5mL) of venous blood was collected and tested for hepatitis B surface antigens, anti-hepatitis C antibodies, and anti-syphilis antibodies using an enzyme-linked immunosorbent assay. Logistic regression, univariate, and multivariate analyses were carried out. A p-value of < 0.05 at a 95% confidence interval was considered statistically significant.

Results

A total of 194 FSWs were included in the study. The seroprevalence rates of HBV infection, HCV infection, and syphilis were 23 (11.9%), 13 (6.7%), and 22 (11.3%), respectively. All three infections were statistically associated with inconsistent condom use (AOR = 1.72, 95% CI: 1.95-5.07, p = 0.03); (AOR = 10.51, 95% CI: 1.62-68.26, p = 0.014); and (AOR = 17.3, 95% CI: 4.55-65.6, p = 0.001). Whereas sex stimulant drug use (AOR = 9.4, 95% CI: 1.002-88.14), intravenous drug use (AOR = 15.53, 95% CI: 1.9-127.99, p=0.011), and sex while having a vaginal ulcer (AOR = 5.72, 95% CI: 1.13-28.9, p=0.035) were all statistically associated with HCV infection.

Conclusion

The prevalence of HBV infection, HCV infection, and syphilis was comparatively higher. Regular screening, health education, and other preventative strategies are advised to lower the STI burden among FSWs.

Prevalence of Hepatitis B Virus infection and associated factors among female sex workers using respondent-driven sampling in Hawassa City, Southern Ethiopia

Background

Female sex workers (FSWs) are a marginalized group notoriously having limited healthcare access and poor-quality care. Inevitably, they are vulnerable to sexually transmitted infections including hepatitis B virus. However; Hepatitis B virus infection is one of the most serious infections and major public health problem considered to be at soaring risk for transmission and acquisition of the infection. Hence, this study was aimed to assess the prevalence and associated factors of HBV infections among FSWs in southern Ethiopia.

Methods

A cross-sectional study was conducted from November to February 2019 at Hawassa city in ISHDO confidential clinic among 383 FSWs. Respondent-driven consecutive sampling was used to select study participants using a standardized questionnaire. Blood sample was collected and viral surface antigen was detected using ELISA from separated serum. Data were entered to SPSS version 21.0. Descriptive and logistic regression analyses were used.

Result

The overall prevalence of FSWs who were tested for HBV using ELISA was 35(9.2%) (95% CI: 6.3–12.1). Among 381 FSWs 249(65.4%) were stayed for 2–5 years in sexual work and 240(63%) of them were used condom consistently during sexual practice. In multivariate logistic regression analysis, FSWs who didn’t use condom were six and two times more risk full to acquire HBV than those who used condom commonly (AOR = 6.38, CI 2.04–18.51) and condom breakage (AOR = 2.10, CI 1.95–4.65), during sexual practice respectively. Similarly, use of stimulants (AOR = 3.25, CI 1.59–18.63), previous history of STI (AOR = 2.15, CI 1.02–6.93), genital ulcer (AOR = 4.64, CI 1.31–11.35), number of sexual partners (AOR = 3.25, CI 1.59–7.47), sex during menses (AOR = 5.85, CI (1.29–21.44), sexual assault (AOR = 2.93, CI 1.23–9.01), sharp material sharing, (AOR = 4.98, CI 1.34–10.95) and history of abortion, (AOR = 2.46, CI 1.18, 12.19), were statistically associated with HBV infection. Factors such as age, residence, and alcohol consumption were not associated with HBV infection.

Conclusion

The prevalence of HBV infection in this study was relatively high compared to the general population. Factors like sociodemographic, behavioral, and previous history-related information were associated with HBV infection shows the need for ongoing screening of high-risk population to inform planning for vaccination and preventive measures.

Epidemiologic profile of hepatitis C virus infection and genotype distribution in Burkina Faso: a systematic review with meta-analysis

Background

Detailed characteristics of Hepatitis C virus (HCV) infection in Burkina Faso are scarce. The main aim of this study was to assess HCV seroprevalence in various settings and populations at risk in Burkina Faso between 1990 and 2020. Secondary objectives included the prevalence of HCV Ribonucleic acid (RNA) and the distribution of HCV genotypes.

Methods

A systematic database search, supplemented by a manual search, was conducted in PubMed, Web of Science, Scopus, and African Index Medicus. Studies reporting HCV seroprevalence data in low and high-risk populations in Burkina Faso were included, and a random-effects meta-analysis was applied. Risk of bias was assessed using the Joanna Briggs institute checklist.

Results

Low-risk populations were examined in 31 studies involving a total of 168,151 subjects, of whom 8330 were positive for HCV antibodies. Six studies included a total of 1484 high-risk persons, and 96 had antibodies to HCV. The pooled seroprevalence in low-risk populations was 3.72% (95% CI: 3.20–4.28) and 4.75% (95% CI: 1.79–8.94) in high-risk groups. A non-significant decreasing trend was observed over the study period. Seven studies tested HCV RNA in a total of 4759 individuals at low risk for HCV infection, and 81 were positive. The meta-analysis of HCV RNA yielded a pooled prevalence of 1.65% (95% CI: 0.74–2.89%) in low-risk populations, which is assumed to be indicative of HCV prevalence in the general population of Burkina Faso and suggests that about 301,174 people are active HCV carriers in the country. Genotypes 2 and 1 were the most frequent, with 60.3% and 25.0%, respectively.

Conclusions

HCV seroprevalence is intermediate in Burkina Faso and indicates the need to implement effective control strategies. There is a paucity of data at the national level and for rural and high-risk populations. General population screening and linkage to care are recommended, with special attention to rural and high-risk populations.

Inevitably, they are vulnerable to sexually transmitted infections including hepatitis B virus. It is one of the most serious and major public health problems, with an increased risk of transmission and acquisition of the infection. Hence, this study was aimed to assess the prevalence and associated factors of HBV infection among FSWs in southern Ethiopia.

METHODS

A cross-sectional study was conducted from November to February 2019 at Hawassa city among ISHDO confidential clinics among 383 FSWs using respondent-driven consecutive sampling techniques to select study participants using a standardized questionnaire. The blood samples were collected to detect viral surface antigen using ELISA. Data were entered into SPSS version 21. Descriptive and logistic regression analysis was used.

RESULTS

The overall prevalence of HBV was 35 (9.2%) (95% CI=6.3-12.1). Among 381 FSWs, 249 (65.4%) of them had stayed for 2-5 years in sexual work. A total of 240 (63%) of them used condoms consistently during sexual practice. In multivariate analysis, FSWs who did not use a condom during sexual practice were 6-times more at risk than those who used a condom (AOR=6.38, CI=2.04-18.51). Condom breakage (AOR=2.10, CI=1.95-4.65), use of stimulants (AOR=3.25, CI=1.59-18.63), history of STI (AOR=2.15, CI=1.02-6.93), and genital ulcer (AOR=4.64, CI=1.31-11.35), number of sexual partners (AOR=3.25, CI=1.59-7.47), sex during menses (AOR=5.85, CI=1.29-21.44), sexual assault (AOR=2.93, CI=1.23-9.01), sharp material sharing (AOR=4.98, CI=1.34-10.95), and history of abortion (AOR=2.46, CI=1.18-12.19) were statistically associated with HBV infection.

CONCLUSION

The prevalence of HBV infection in this study was relatively high compared to the general population. Factors like sociodemographic, behavioral, and previous information were associated with HBV infection. There is a need for ongoing screening of this high-risk population to inform planning for vaccination and preventive measures.

Seroprevalence and Associated Factors of Human Immunodeficiency Virus, Treponema pallidum, Hepatitis B Virus, and Hepatitis C Virus among Female Sex Workers in Dessie City, Northeast Ethiopia

Introduction

Sexually transmitted infections (STIs) are prevalent in Ethiopia and elsewhere among different population groups particularly among female sex workers (FSWs). Because of their work and their behavior, FSWs are at high risk to acquire STIs. The aim of the study was to assess the seroprevalence and associated factors of HIV, HBV, HCV, and T. pallidum among FSWs in Dessie City, Northeast Ethiopia.

Methods

This cross-sectional study was conducted in Dessie City, Amhara Region, Northeastern Ethiopia, from November 2017 to April 2018. A total of 360 FSWs whose age is greater than or equal to 18 years and who are willing to participate were recruited by simple random sampling technique. Interview-based questionnaire was administered, and 5 ml of venous blood from each participant was drawn under aseptic conditions. The rapid test was performed to obtain the result of the four STIs (HIV, T. pallidum, HBV, and HCV). The collected data were entered and analyzed by SPSS version 20.0. From the bivariable analysis, variables having P value < 0.2 were retained into multivariable analysis. From the multivariable analysis, variables with P value < 0.05 were affirmed as statistically associated factors. Adjusted odds ratios and their 95% confidence intervals were used as indicators of the strength of association.

Results

Majority of study participants were urban dwellers, 10 (2.8%) respondents were married, 61 (16.9%) have more than two children, and more than half of them were at the age range between 18 and 27 years. Any infection with STIs was 84 (23.3%), whereas 27 (7.5%), 47 (13.1%), 2 (0.6%), and 45 (12.5%) study participants were positive for laboratory test of HIV, HBV, HCV, and T. pallidum, respectively. Marital status, sharing of sharp materials, breakage of condom, number of customers per week, genital discharge, and pain had significant association with any STI.

Conclusions

In comparison with different research works in Ethiopia and abroad, the prevalence of any STI, HIV, HBV, and T. pallidum was found to be relatively high. Preventive approach and appropriate treatment of STIs should be developed. Concerned body should work together to alleviate the problem by counseling and recruiting them on other productive job sectors in the country.
