Among the NonA-nonB hepatitis, only hepatitis C is exclusively of parenteral transmission. The reported seroprevalence among blood donors in the world ranges from 0.5 to 6.0%. In order to discover the seroprevalence of anti-HCV in candidates for blood donation at the General Hospital of Mexico, 330 individuals were studied. Determination of anti-HCV was performed by the UBI HCV EIA diagnostic test. Risk factors such as history of major surgery, transfusions, drug addiction, etc were also assessed. There were only 4 seropositive patients (1.2%), 95% CI = (0, 2.75%). Only major surgery was associated with seropositivity. It was not possible to exclude hemotransfusion during surgery as a risk factor.
