So your doctor is only at risk if he takes that dirty needle, sticks it in his arm and draws his blood back into the syringe and then he must inject
that blood back into his body, which is then at that point 'mixed,'as you
say, with the infected blood,,,,,ONLY THEN he is at risk? Its hard to believe you're serious.But I know you are.
btw I don't like if a health care worker doesn't wash their hands before they touch me. I don't allow it.
