Prevalence of hepatitis B and C viruses infection among military personnel at Bahir Dar Armed Forces General Hospital, Ethiopia

Abstract

Background: Military personnel are high-risk people for parenteral and sexually transmitted diseases such as hepatitis B virus (HBV) and hepatitis C virus (HCV). Data regarding HBV and HCV prevalence among military personnel in Ethiopia is limited. Hence, the study aimed to determine sero-prevalence and associated risk factors of HBV and HCV among military personnel at Bahir Dar Armed Forces General Hospital, Ethiopia. Methods: A cross-sectional study was conducted in a total of 403 military personnel from February to May 2015. Socio-demographic characteristics and risk factors were collected through face to face interview using structured questionnaire. HBV and HCV infection was determined using HBsAg and anti-HCV antibody rapid tests. Logistic regression analysis was employed to assess possible risk factors for HBV and HCV infections. Results: The sero-prevalence of HBV and HCV infection were 4.2 and 0.2 %, respectively. None of the study subjects were co-infected with HBV and HCV. Higher prevalence of HBV infection (11.3 %) was observed in the age group of 40 and above. Being at the age of 40 years and above (COR 7.6; 95 % CI 2.0-29.0, p = 0.003), history of nose piercing (COA 5.9; 95 % CI 1.2-29.9, p = 0.033) and sexually transmitted infection (COR 4.3; 95 % CI 1.1-16.4, p = 0.03) were significantly associated with these viral hepatitis infections. Conclusion: Intermediate prevalence of HBV and low prevalence of HCV were observed among military personnel. Strengthening HBV screening strategies among military personal may further reduce these viral diseases.
