Emerging risk factors associated with prevalence of Hepatitis C Virus infection among Nigerians: Findings from blood donors in an academic hospital, Enugu Southeastern Nigeria

AIM: In Nigeria, reports on the prevalence of Hepatitis C risk factors have not been clearly elucidated, we investigate the risk factors that influence the prevalence and how the difference in awareness level of risk factors screening across age groups contributes to the disease. METHODS: A total of 8790 aged 18-55 years old, who attended the Department of Haematology and Blood Transfusion Services, University of Nigeria Teaching Hospital, Enugu were screened. Among them, 135 were diagnosed with hepatitis C infection from 1 January 2017 to 1 January 2019. Participants completed a questionnaire related to demographics, risk factors, history of previous medical screening. Age groups, income and education were indicators. Multivariate analyses were used to identify correlates. RESULTS: A total of 135 blood donors (95 males and 40 females) with a mean age of 35.9 +/- 10.5 and 36.4 +/- 10.7 years respectively were positive for hepatitis C infection, giving overall prevalence (1.5%), injecting drug use (39%), unprotected multiple sex (22.2%), sacrification (14.8%), blood transfusion (11.1%). Multivariate analysis revealed that injecting drug use (P < .0001), unprotected multiple sex (P = .004), sacrification (P = .036) were independent risk factors that influence the prevalence among younger age groups. Blood transfusion was not significant (P = .053) but the mostly accessed. Low income and educational background were significantly more prevalent among the studied group. CONCLUSION: Injecting drug use, multiple sex and sacrification are independent predictors of prevalence of Hepatitis C infection. The early onset of the risk factors among the younger adult clearly underlines the need for early screening and interventions.
