Positive PPDs and mTB Screening. When should you worry? (Group)
CDC’s Office of Blood, Organ, and Other Tissue Safety is tasked with coordinating investigations of infectious disease transmission from donor to recipient through blood product transfusion, solid organ transplantation, and tissue implantation. This presentation describes two investigations of infectious disease transmission through tissue implantation – Mycobacterium tuberculosis transmission through a bone allograft product and Mycoplasma hominis transmission through amniotic tissue. These investigations highlight gaps in tissue safety and traceability in the United States and suggest possible ways to enhance the safety of tissue implantation.
