The New Hampshire hospital lab technician indicted last week for infecting 31 people with Hepatitis C might have infected "tens of thousands" of patients in at least 13 hospitals, ABC News has learned.
David Kwiatkowski, a former lab technician at Exeter Hospital in New Hampshire, had allegedly been stealing the Fentanyl syringes intended for patients, injecting his own arm and then refilling those empty syringes with another liquid-like saline, according to a statement from the United States Attorney's Office in New Hampshire.
Since Kwiatkowski tested positive for Hepatitis C in June 2010, he passed it on to the hospital patients who were injected with his used, saline-filled syringes, according to the affidavit.
