Abstract:
1581 person from 2 different geographic areas of Thanh Hoa province participated in the serosurvey of hepatitis B and C (HBV and HCV) virus in August 1998. They were divided into 4 age groups representative of different modes of viral transmission; 2 infant groups: 9-18 months old and 4-6 years old, adolescent group 14-16 years old and adult group 25-40 years old. Nearly half of the surveyed people were exposed to HBV, the rate of HBsAb positive increased with age and up to 81,4% of adults. The rate of HBsAg carriers was 17% there was no significant difference between age groups. More than 85% of infant HBsAg carriers were HBeAg positive, these rates on adolescent and adult were lower. HBsAb increased with age and only 3,4% of infant 9-18 months old had this antibody. Only 6 samples and no one of infant were positive among 1563 anti-HCV tests.
