Background. THepatitis C is a chronic viral disease for which a very effective pharmacological treatment is available. The aim of the present study was to analyse hepatitis C virus (HCV) seroprevalence in population aged ≥5 years in Catalonia in 2002, and to compare the seroprevalence found in 2002 with the prevalence found in a study carried out in 1996. Methods and Results. A representative sample (N=2620) of the population aged ≥5 years in Catalonia was obtained. Serum samples were obtained, and ELISA and RIBA assays (Ortho Diagnostics) were used to determine the seroprevalence of HCVinfected people. The prevalence of HCV infection in 2002 was 1.3%, 1% in men, and 1.5% in women. The prevalence of HCV infection was associated with parenteral drug abuse (ORadj=36.5, p<0.01), tattoos (ORadj=26.1, p<0.001), and blood transfusions (ORadj=6, 8, p<0.005). Prevalence of HCV infection had been reduced by 48% between 1996 and 2002 (2.5% vs. 1.3%). Conclusions. Prevalence of HCV infection was estimated to be 1.3% in 2002. A decrease in HCV prevalence occurred between 1996 and 2002, possibly due to preventive activities developed in Catalonia.
