Hepatitis B and C virus infection prevalence among women in Manila, the Philippines.
A seroepidemiological survey of HBsAg, HBeAg, anti-HBs, anti-HBc, anti-HBe and anti-HCV positivities was conducted in 1997 in Manila, The Philippines. Adult women (21 to 59 years of age) were invited to donate peripheral blood for the study, and 50 people volunteered. They were nonsmokers, nonhabitual drinkers, and mostly married; none of them was a professional blood donor. The serum assay showed that all subjects were negative for HBsAg and HBeAg. Overall, a half (50%) of the study subjects were positive for any one of the HBV infection markers (i.e. HBV+). The older group (25 women at 36-59 years of age) showed significantly higher prevalence than the younger group (25 women at 21-35 years of age) of positivity to all three HBV antibody markers and therefore HBV positivity also. None of the study subjects was positive for anti-HCV. Comparison of the present findings with the results reported in the literature for the 1980s suggests that the risk of HBV infection and most probably that of HCV infection also has decreased in this 10-year period in the Philippines.
