David Kwiatkowski, a traveling medical technician who was hired by Exeter Hospital in October 2011, has been charged with spreading hepatitis C there when he allegedly injected himself with painkillers meant for patients and left the syringes to be reused. Over the last five years, Kwiatkowski also worked on a contract basis at hospitals in Arizona, Georgia, Kansas, Maryland, Michigan, New York, and Pennsylvania, and officials in these states want to determine if he may have spread the disease to patients at those facilities as well. Triage Staffing, which placed Kwiatkowski at Exeter Hospital, faces a negligence complaint and a class action lawsuit in U.S. District Court in Omaha, NE.
