Background: Hepatitis B virus (HBV) remains a major global health problem. More than
three-quarters of HBV infections occur in Asia, the Middle East and Africa. Healthcare workers
(HCWs) are at risk of acquiring hepatitis B (HBV), hepatitis C (HCV) and human
immunodeficiency virus (HIV) infections via exposure to patients’ blood and body fluids.
Hepatitis B virus infection is a recognized occupational hazard as non-immune health
professionals stand at risk of getting infected from their work.
Objectives: The study aimed at investigating the distribution of HBV and associated risk
factors among health professionals in public hospitals, Addis Ababa, Ethiopia.
Methods: Data were obtained from a cross sectional survey conducted in St. Paul’s and Zewditu
hospital, Addis Ababa, Ethiopia among health professionals from November 2010 to January
2011. A convenient sampling method was employed to get the required sample size. A structured
questionnaire was used to collect data on socio-demographic characteristics and risk factors. A
5ml blood was collected, centrifuged and the serum was analyzed for HBsAg using Instant
HBsAg kit. Descriptive and logistic regression models were used for analysis.
Results: Among the 254 participants, the sero-prevalence of current hepatitis B virus infection
was 2.4%. Majority of the study subjects, which account 184(72.4%) and 153(60.2%) of them
were exposed for blood while ungloved and for other body fluid, respectively. Prevalence of
sustained needle stick injuries (NSIs) and sharp injury was 155(61.2%) and 127(50%),
respectively. Consistent use of gloves was reported by 52.4% of respondents. Only 9(3.5%) of
respondents were vaccinated against hepatitis B virus infection. HCWs who had no knowledge
about universal precaution guidelines were more likely to have been exposed to hepatitis B virus
infection (AOR=7.96; 95% CI: 1.295-48.966; P= 0.025).
Conclusion and Recommendation: Exposure for potentially infectious body fluids, NSI
and sharp injury and other risk factors was high in this study. However, yet only very small
percentages of health professionals were vaccinated. Therefore, health professionals should be
vaccinated at the time of entry in service and universal precaution should be emphasized for
preventing the occupational risk for HBV among health professionals.|
