INTRODUCTION: Hepatitis C virus (HCV) infection and human immunodeficiency virus (HIV) infections are public health problems in sub-Saharan countries such as the Republic of Congo. HIV infection could impact the characteristics of HCV infection in co-infected people. We investigated HCV-HIV co-infection among blood donors in Congo.METHODOLOGY: Ninety-nine HIV-positive and/or HCV-seropositive blood donors were selected during screening and subsequently tested for aminotransferases and HCV RNA.RESULTS: A total of 29 donors were found positive for HCV RNA (HCV-infected individuals), including 19/60 (31.66%) HIV donors (co-infected) and 10/39 (25.64%) non-HIV donors (mono-infected). Most of the co-infected donors (17/19) displayed a high viral load (> 5 log). The median HCV RNA level was at least 2 logs higher in co-infected people. The levels of alanine aminotransferase (ALT) were also slightly higher in co-infected donors than in HCV mono-infected donors.CONCLUSION: This study reports HCV-HIV co-infection among blood donors in Congo and shows that HCV viral load is higher in HIV donors.
