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