Introduction: Hepatitis B Virus (HBV) and Human Immunodeficiency Virus (HIV) are among the leading causes of infectious disease deaths worldwide.  In Sub Saharan Africa, the two viruses are highly endemic among pregnant women. With co-infection risk of perinatal transmission cannot be under-estimated.

Methods: This study utilized a descriptive cross sectional design that sought to establish the seroprevalence of HBsAg among HIV positive pregnant women at JOOTRH. Participants were recruited at the reproductive health department. Ethical approval was obtained from the joint Kenyatta National Hospital and University of Nairobi Ethics and Research Committee and ethical considerations were observed throughout the study. Standardized tools were used for data collection. SPSS was utilized in data entry and processing while descriptive statistics were used in data analysis.

Findings: A total of 125 study respondents participated in this study. Majority (32.3 %( n=40)) of the respondents were aged between 31 to 35 years followed by 27.7% (n=35) (26-30 years). Ages 16 to 20 constituted 12.3 %( n=15) while ages 21 to 25 accounted for 20 %( n=25). Most of the respondents were married (72%, n=90). The study established a co-infection rate of 1%. There was no correlation between demographic characteristics and risk factors for HBV and HIV co-infection.

Conclusion: Sero-prevalence of HBsAg among the respondents was low. There is need to focus on similar studies in other parts of Nyanza region.
