Summary

This study followed 1,771 adults and children who received blood transfusions to check how safe the blood supply is. Researchers tested patients' blood for viruses like HIV and hepatitis before and after transfusion, and stored samples for future testing. The goal was to keep blood transfusions safe and quickly spot any new infection risks.
