  1. The declining pattern of seroepidemiology of hepatitis A virus infection among adolescents in Bangkok, Thailand.

    Article - En anglais

    Hepatitis A virus (HAV) is a health problem in countries where seroepidemiology shows changes from hyperendemicity to intermediate endemicity.

    Throughout the last decade, we studied, in Bangkok, the seroprevalence of hepatitis A virus antibody (anti-HAV) among adolescents of different age groups.

    In 1996,245 serum specimens from children aged between 10 and 19 were tested for anti-HAV by ELISA method.

    The results were compared to those obtained in 1987 and 1993 from students of the same age and attending the same school.

    Anti-HAV was detected in 31.4%, 14.6% and 12.7% of school children in the years 1987,1993 and 1996, respectively.

    Each year, it was found that an increasing prevalence of anti-HAV was related to an increasing age.

    From 1987 to 1996, the age specific prevalence of anti-HAV was markedly decreased in younger children.

    The surveillance of the epidemiological trend of HAV infection is important for implementing preventive measures and for controlling the disease.
