I've donated regularly for years. All needles and equipment is sterile and single-use so I really don't see how it would be possible to be infected with anything.
I did give concentrated red cells once where they hook you up to a small centrifuge device. The feeling when it pumps clarified blood back into your vein is one WEIRD feeling indeed.
