On Thursday, Newsweek published a cover story on former hospital technician David Kwiatkowski, who was convicted of infecting 45 patients with hepatitis-C in eight states over nine years.

Kwiatkowski was employed as a technician for a time at Hays Medical Center.

He spoke to Newsweek’s Kurt Eichenwald, telling his story for the first time and even risking his own safety in the hopes of spreading the word of what he did and trying to help other hospitals from preventing similar acts from happening.
