It is scary that a nurse/doctor would reuse syringes... that's just greed or laziness.
My sister was once having a blood test, and then a nurse stabbed herself with the needle. The hospital took more blood from my sister for HIV and Hep C tests to make sure the nurse would be OK... and had the audacity to try and charge my family for the tests!
However, getting HIV/AIDS from a blood transfusion is a totally different story. Tests are never, and I mean NEVER, 100% accurate, even if run perfectly they are maybe 99.99%. If someone was recently infected with the virus, their titer is below the sensitivity level of the test anyways. This is exactly why people who engage in high risk behavior either should not donate or at least be honest so their blood will be tossed. I feel very badly for this person, but don't blame the hospital. Blame the jerk that got the disease and chose to donate anyway and/or lied on their questionaire.
