Hepatitis B infection (HBV) infection is a serious public health problem worldwide and its co-infection with human immune deficiency virus (HIV) is common due to shared routes of transmission. An increased mortality due to accelerated hepatic disease progression and the frequent hepatotoxicity caused by antiretroviral therapy are the challenges in the clinical management of HIV. Epidemiological studies on HBV and HBV/HIV co infection are scarce in Ethiopia, particularly at the study area. The aim of this study was to determine the magnitude of HBV, its risk factors and co-infection with HIV among clients of a voluntary counseling and testing (VCT) center in Southern Ethiopia. A facility based cross-sectional study was conducted from 1st February 2016 to 15th March among clients of Nigist Eleni Memorial Hospital VCT Center. Data were collected by face-to-face interview and specific formula sheet as well recorded results of laboratory diagnosis of blood sample from each participant. Both descriptive and inferential statistics were used for data analysis. Multivariable logistic regression modeling was done to identify predictors of HBV. Overall, 331 participants were included in the study. The prevalence of HBV was 8.8%, HBV/HIV co-infection was found in 3.6%. Individuals with a history of multiple sexual partner [AOR = 10.3; 95% CI, 3.71 - 28.83], previous history of invasive procedure [adjusted odds ratio (AOR) = 10.88; 95% CI, 3.84 - 30.86] and history of surgical procedure [AOR = 9.2; 95% CI, 3.1 - 27.88] were identified as in dependent predictors of HBV infection. High HBV infection and HBV/HIV co-infection was found in the study. Previous history of surgical procedure, invasive procedure and multiple sexual partners were identified as independent predictor of HBV infection.
