Blood can transmit Creutzfeldt-Jakob disease

Creutzfeldt-Jakob disease (CJD) is a rare but fatal disease in humans. For the first time, the presence of infectivity in the blood of patients affected by sporadic and the new variant of CJD has been established by scientists. Complementary investigations are underway, but the available results support the contention that CJD might be transmitted by blood transfusion and/or the use of blood derived products.
