Which practice was a primary breach behind hepatitis outbreaks in ambulatory care facilities?

1. Four large outbreaks of hepatitis B and hepatitis C among patients in ambulatory care were investigated in the United States. 2. One primary breach was reinsertion of used needles into a multiple-dose vial or solution container such as a saline bag. 3. The other was use of a single needle and syringe to give intravenous medication to more than one patient. 4. Preparing medication away from the area where used needles and syringes are handled is a safeguard, not a breach. 5. A fresh needle and syringe per patient and a single-dose vial for one patient are both correct practice. _Source: CDC Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings (2007), Part III, section III.A.1.b.
