Not enough for a breach like that.
From my point of view:
- Reused needles/syringes to draw up medication and then applied it.
- Used medication bottles (e.g. propofol) for multiple patients.(I still learned to do that,but in theory there is a risk. Looking back I can't fathom we once did that)
- Used private laryngoscope for patients and did not clean it properly (my best guess atm)
- Has HIV+Hep himself and used some unsafe techniques that may have led to skin penetration on his side.
Or of course...well...a bad faith actor who intentionally infected people.
