Serum samples from 123 males and 123 females collected by age in 1996 were analyzed for antibodies against surface antigen of Hepatitis B virus and C22-3, C200 antigens of Hepatitis C virus. Sera from the children under the age of 10 showed 30% seropositivity to the surface antigen of Hepatitis B virus, 33.3% in $10{sim}19$ year group, 20% in $20{sim}29$ year group, 17.6% in $30{sim}39$ year group, 3.3% in $40{sim}49$ year group, 5.9% in $50{sim}59$ year group, 8,3% in $60{sim}69$ year group, 2.9% in $70{sim}79$ year group, but antibody could not found in $80{sim}86$ year group. 12 out of 123 male sera were positive, 19 out of 123 female sera were positive and overall rate of positivity of antibody against surface antigen of Hepatitis B virus was 12.6%. Serum samples from peoples under the age of 30 had not antibody against C22-3, C200 antigens of Hepatitis C virus. The positivity rate was 2.9% in $30{sim}39$ year group. 5 out of 30 sera from $40{sim}49$ year age group were positive, and 3 positive sera showed extremely high titer (1:524,288) but the titers of two remaining sera were 1:32, 1:8,192 respectively. 5.9% was positive in $50{sim}59$ year group, 8.3% in $60{sim}69$ year group, 11.8% in $70{sim}79$ year group but all negative in $80{sim}86$ year group 6 out of 123 male sera were positive (4.9%), 9 out of 123 female sera were positive (7.3%). Overall rate of positivity of antibody against C22-3, C200 antigen of Hepatitis C virus was 6.1 %. None out of 246 sera had both antibodies against Hepatitis B virus and Hepatitis C virus.
