Wait... need some clarification here
"Dr. Gina Michael, the association chief of staff at the hospital, told the affiliate that some dental technicians broke protocol by handwashing tools before putting them in cleaning machines. The instruments were supposed to only be put in the cleaning machines, Michael said."
So we have people doing dental procedures who decide to rinse their instruments after procedures before putting them in the autoclave. Obviously these instruments would not include needles, and any non-metallic instruments are going to be dumped in the medical waste trash. So then the only likely way for HIV infected blood to transfer between hosts would be for someone to wash their hands at the sink with some level of contact, and then put their washed hands onto an open wound. Now all the dentists I've known use latex gloves, so their washed hands are safely separated from their patient.
Given that, I'd say the chances of the dentist getting HIV from this rinsing practice have to be incredibly higher than any of their patients, and the entire concern is blown out of proportion. Can anyone in the medical field verify what I'm missing here?
