Let's throw another wrench in...how about health care workers??? As an EMT I had to get tested for TB and vaccinated for Hep-B. Now, why Hep B and not HIV??? Because of the stigma of being HIV positive??? Me, personally, if you're gonna be working on me in the event of a trauma situation and there's a slight possibility that our blood might be mixing, I'd want to be confident that you're free from any communicable diseases.
