Information is very scarce on the co-infection of human immunodefficiency virus (HIV) with hepatitis-B virus (HBV) infection among patients receiving treatment for infectious diseases in Nigeria. 80 samples were analyzed in this study and were evaluated for the presence and qualitative detection of HIV and HBV surface antigen using a lateral chromatographic immunoassay kit (BC-ABON HIV, ABON HBsAg) among patients aged (11-74 years) attending Federal Teaching Hospital Abakaliki (FETHA), Nigeria. Twelve (15%) of the patients examined were seropositive for HIV, while ten (12.5 %) patients were HBsAg seropositive. A higher HIV seroprevalence was recorded in the females (20 %) than males (10 9%) among the patients. A slight higher HBsAg seroprevalence were observed in males (15 %) than females (10 %) with the highest prevalence of HBsAg occurring in the 11-20 and 51-60 years age group (16.67 %), followed by those of 41-50 years (12.5%). Results of the co-infection of HIV with HBV revealed that 5 (62.5 %) were seropositive for both HIV and HBV surface antigen with a considerably difference observed in male (10 %) than in female (2.5 %). Results confirmed the high endemicity of HBV infection among patients attending FETHA Ebonyi State, Nigeria and the significantly greater prevalence of HIV infection than HBV among infected patients.
