Fungal infection can occur in transplant patients via one of four mechanisms: donor-derived infections, contamination during the transplantation period, reactivation of latent infection in the host, or new infection during the posttransplantation period. Distinguishing between these mechanisms is often difficult and as a result, donorderived fungal infections may be under-recognized with few data on its prevalence. We review published reports of donor-derived fungal infections and discuss the role of donor screening and the importance of establishing a national reporting, tracking, and notification system for transplant-transmitted infections.
