I was shocked to learn that Isaac Asimov died from complications of AIDS acquired via transfusion, but his doctors insisted on keeping it a secret from the public.
For the most part our blood supply has good protection for blood born illness (between rules that prevent the high risk from donating and testing). That wasn't always the case. It is best to keep the mistakes of the past un talked about so that we don't spread fear of the blood supply which would kill far more people.
