 Hospital patients in the Portland, Oregon area may have been exposed to diseases like hepatitis and HIV because of a doctor's disregard for safety protocols. Both Providence and Legacy Health confirmed that the actions of a single anesthesiologist may have been responsible for over 2,400 infectious disease exposures. According to the hospitals, the physician had worked for the Oregon Anesthesiology Group, which both hospitals had contracts with. That physician is no longer employed by the group.
