Problem
A 32-year-old man recently donated blood. Upon routine testing, the donor was found to be HIV-antibody positive as confirmed by Western blot. When the donor's history was reviewed in the blood center's computer file, he was found to have 1 previous donation in 2016. Red blood cells, a platelet concentrate, and FFP were prepared from the 2016 donation. In adherence to FDA recommendations, each of the hospitals to which the components from the 2016 donation had been shipped was officially notified. In following the recommended "lookback" procedure, it was determined that the platelet concentrate had not been used, the FFP was still frozen, and the RBC had been transfused to a 48-year-old woman undergoing hysterectomy for dysfunctional uterine bleeding associated with multiple, large uterine tumors.
a) Following the "lookback"; process, what would the next steps be?
b) Currently, which transfusion-transmitted infectious diseases are subject to lookback?
