Prevalence of anti-HCV in subjects of various age groups

812 serum samples from 382 males and 430 females from various age groups were examined. All the samples were tested for anti-HCV hepatitis C virus, anti-HBc and HBsAg with an enzymeimmunoassay. The total serum prevalence was 2.9% for anti-HVC, 22.2% for anti-HBc and 4.6% for HBsAg. The seropositivity rates of anti-HCV and anti-HBc tended to increase with age, while for HBsAg a more regular pattern was observed for the different subject groups. The fact that anti-HCV are more frequently found together with HBV markers confirms the existence of similar modes of transmission of the two viruses.
