ABSTRACT: Viral hepatitis B and C infections are among the leading cause of death in Sub-Saharan Africa. Lack of knowledge and awareness in the general population as in health care settings may enhance the propagation of these diseases. We aimed at determining the prevalence of HBV and HCV in Ebola survivors and health care workers (HCWs) of the Makeni town in Sierra Leone. We conducted a cross-sectional study during the last 2013-2016 Ebola outbreak in Makeni among Ebola survivors (N = 68) and 81 Health care workers from Holy Spirit hospital and Loreto clinic, two health care facilities in Makeni district. Serological markers of HBV (HBs Ag, anti-HBs Ab and anti-HBc Ab) and anti-HCV antibodies detection were done using ELISA techniques. The positive detection rates for HBs Ag, anti-HBs Ab and anti-HBc antibodies in Ebola survivors were 23.53% (16/68), 32.35% (22/68) and 88.89% (16/18) respectively. Survivors with a current HBV infection had a positive rate of 38.89% (7/18) and 16.66% (3/18) of them were considered immune due to past HBV infection. HCV prevalence was 26.47% (18/68) and about 10.29% (7/68) were HBV/HCV co-infected. The positive detection rates of HBsAg, anti-HBs Ab and anti-HBc Ab were 37.07% (30/81), 33.33% (27/81) and 30.86% (25/81) respectively in health care workers. We observed that 4.94% (4/81) of the HCWs were currently infected with HBV. Participants considered as immune due to past infection represented 23.47% (19/81) and those immune due to vaccination represented 2.47% (2/81). The prevalence of HCV infection among health staff was 2.47% (2/81) with 1.23% (1/81) being HBV/HCV co-infection. Our findings showed that viral hepatitis infection is a burden for Sierra Leone government. There is an urgent need to develop and implement strategies that could improve population immunization against HBV and vulgarization of HCV treatment programs.
