The positive rate of HBsAg in urban and rural areas were 21.70% and 22.80% respectivcly. Infection rate of 5～9 years was 27.60% and that of 30～34 years was highest (51.10%)in urban arcas. The infection rate of 5～9 years(41.88%) was higher than that of 30～34 age group (38.70%) in rural samples. 136 (65.1%) of 209 families were found to have at least one HBsAg positive member. Overall family clustering rate of HBsAg was 52.60%. Clustering rate of urban areas was 57.90% and that of rural was 48.80%. The difference is not significant statistically (P>0.05) . The HBsAg and anti-HBs positive rate of children was closely related to the mother's status. The HBsAg-anti-HBs was higher in offsprings of HBsAg carring mothers (40.0%) than those of HBsAg negative mothers (25.40%) . The difference is statistically significant (P<0.001).
