ABSTRACT
The prevalence of infection by hepatitis B (HBV) and C (HCV) viruses varies among geographical regions. In order to determine the prevalence of HBV and HCV infection in voluntary blood donors we evaluated the prevalence of HBsAg, anti-HBc, and anti-HCV markers of 128,497 blood donor samples collected from 1998 to 2005 in the state of Rio de Janeiro. These markers were analyzed by immunoenzymatic tests, as determined by the Ministry of Health. Data were obtained from the Sorology Laboratory of the Hemoterapy Service of the Instituto Nacional de Câncer, Rio de Janeiro. Overall prevalence estimates were 0.27 percent for HBsAg, 3.68 percent for anti-HBc, and 0.90 percent for anti-HCV. There was a significant decrease in the overall prevalence of HBsAg (from 0.36 to 0.14 percent) and anti-HBc (from 6.12 to 2.05 percent) in the period encompassed between 1998-2005. Similarly, there was a decline in anti-HCV prevalence rates in Brazilian blood donors, from 1.04 percent in 1998 to 0.79 percent in 2004, with an increase of HCV prevalence to 1.09 percent in 2005. These prevalence estimates were higher than those found in other countries, indicating high rates of infection by HBV and HCV and a persistent risk of HBV and HCV transmission by transfusion.
