Summary: A decrease in or leveling off of new cases of transfusion-related AIDS coupled with continued increases in homosexual and IV drug cases suggests that intervention by barring contaminated blood has worked and “education” has worked less well, if at all. Current evidence suggests that the blood-bar resulted in change in new AIDS cases among children within 3 years and among adults within 3 1/2 years.
