Ad Hoc Disease Transmission Advisory Committee
The Ad Hoc Disease Transmission Advisory Committee (DTAC) considers issues related to the transmission of disease through organ transplantation. The Committee examines potential disease transmission cases reported to the OPTN in an effort to confirm transmissions where possible. It reviews aggregate data on cases to assess the risk of donor disease transmission in organ transplantation in the U.S. with the goal of providing (1) education and guidance to the transplant community toward preventing future disease transmission and (2) input in developing policy to improve the safety of organ donation through the reduction of donor derived transmission events. It may identify disease-transmission related patient safety issues to be addressed, as appropriate, by the OPTN.
Compiled by the Ad Hoc Disease Transmission Advisory Committee (DTAC), see the latest information known for minimizing the risk of donor-derived COVID-19 transmission while maximizing donor utilization. DTAC has committed to reviewing the document quarterly.
