The man accused of infecting patients with hepatitis C at a New Hampshire hospital was fired from a job in Arizona two years ago after testing positive for cocaine and marijuana, a public relations agency for Arizona Heart Hospital said Thursday.
David Kwiatkowski was arrested this month in connection with spreading the disease to 30 patients at Exeter Hospital in New Hampshire.
Kwiatkowski, 33, also worked as a traveling medical technician on a contract basis for hospitals in Arizona, Georgia, Kansas, Maryland, Michigan, New York and Pennsylvania in the past five years, hospitals and health officials in those states said.
They are trying to get the hundreds or thousands of patients who may have come in contact with him to be tested for the disease.
Kwiatkowski has been treated for the disease, which can pass through contact with contaminated blood, most often via shared needles.
