Risk of transfusion‐transmitted infections among returned high‐risk deferred donors: A cohort study

Individuals with a history of bloodletting, tattooing or high-risk sexual contact were at a higher risk of HBV and HCV infection, highlighting the effectiveness of donor selection procedures. Endoscopy and needle stick injuries were not associated with an increased TTI risk, emphasizing the need for further research to reassess these deferral criteria. Blood centres should monitor the efficacy of donor selection criteria while emphasizing proper donor selection and counselling.
