Like vascularized transplants, tissue allografts are able to transmit viral and bacterial diseases. Transmission of HIV (Human Immunodeficiency Virus) and HCV (Hepatitis C virus) has been proved for sterilized, unprocessed and deep-frozen allografts. It is the prime responsibility of the tissue bank to select the donor correctly and to perform careful biological screening. However, standard screening is not enough to detect a seronegative but contaminated donor. It is necessary to quarantine the tissues until complementary screening confirms the absence of viral disease. If secondary screening is not possible, the tissues should be discarded or should be processed. If donor selection, relevant and appropriate screening tests and adequate procurement of tissues are carefully made, then the risk of disease transmission from tissue allografts will remain remote.
