The study determine the seroprevalence of HBV and HCV and associated risk factors among apparently healthy individuals in three semi -urban communities of Bauchi state, Nigeria. The cross-sectional study was conducted in three communities of Bauchi state between July and August 2017. A well-structured questionnaire and informed consent was administered, and rapid diagnostic kits was employed for sero detection of HBsAg and anti- HCV. Appropriate statistical package employed for data analysis. Of the 637 participants, comprised of 284 (44.6% ) males and 353(55.6%) females, overall prevalence of 23.7%, HBsAg was detected in 20.7% (n=354) , Anti-HCV in 3.1%(n=93),and no co-infection. Statistical significant association was observed between socio-demographic variables and seroprevalence (p<0.05) except Anti-HCV and marital status. Increased HBsAg prevalence was observed with the age-group, and male participants. Similar prevalence among participants with tertiary and non-formal educational background, married and single, and civil servants. Overall risk factors analysis revealed statistical significant association between the risk factors and seroprevalence with HBV (7 out of the 12) (p<0.05), HCV (1 out of the 12) with unknown alcohol consumption (p<0.05). The study findings furthered affirmed high prevalence of HBV and HCV in the communities, constituting a serious public health problem. Therefore, there is need for public health education, awareness and knowledge, and mass vaccination of the populace to stem down the tide of high prevalence rate.
