Prevalence of hepatitis B and C virus infection among working women in Bangkok.
A small-scale seroepidemiological survey on hepatitis B and C virus infection was conducted in the vicinity of Bangkok, Thailand, in 1998. Adult women working in a health sciences institution were invited to participate in the study, and 52 subjects (19 to 57 years of age) volunteered to offer peripheral blood. They were non-smoking and non-habitually drinking, and about two thirds of the subjects were married. The sera from the blood samples were assayed for HBsAg, anti-HBs, anti-HBc, and anti-HCV positivities. The serum assay showed that none of the subjects was positive to HBsAg or anti-HCV, but a half of the subjects (50%) were either positive to anti-HBs, to anti-HBc or to the both, thus having experienced HBV infection in the past. The prevalence of the positivities was significantly higher among those at 35-57 years of age than those younger than 35 years. Comparison of the present findings with the results reported in literature suggested that the risk of HBV infection should have been higher than that of HCV infection, that the observed positivity of HBV infection was probably lower than ever reported, and that anti-HCV positivity should be the lowest.
