ABSTRACT

The risk of transmission of infectious viral diseases by blood transfusion has diminished but it has not disappeared. Detection methods are focused in diseases, such as hepatitis B and C and HIV. However, there are new pathogen agents that can be transmitted by blood transfusion, such as the TT virus, that was isolated from a patient with post-transfusion acute hepatitis of unascertained etiology. The prevalence of this virus presents a wide variability (1-80 %). It is more frequent in patients who have had blood transfusions. Its transmission has been associated to chronic hepatic illnesses.
