HHV-8 is a pathogenic virus. However, it is still unclear whether HHV-8 can be transmitted by blood transfusion. The article gives some evidence that
blood transfusion is, if at all, a minor route for transmission of HHV-8, at least when leukodepleted blood is used. The major route is the sexual route. However, the real risk of transmission of HHV-8 by blood transfusion still could not be answered by the study.
