The Exeter Hospital Hepatitis C outbreak is not uncommon unfortunately. Although it is not in New Hampshire, below is an interesting case I found on Hepatitis C.
Former Colorado surgical tech reveals details of stolen drugs, Hepatitis C outbreak
As part of her plea arrangement with federal prosecutors, a former surgical technician at a Colorado Hospital explained how she infected at least 15 patients with hepatitis C by giving them needles she had used to feed her drug addiction to the painkiller Fentanyl.
Kristen Parker, who worked at Rose and later the Audubon Surgery Center in Colorado Springs, was arrested in 2010 and pleaded guilty in 2011 to a variety of charges based on stealing Fentanyl.
She admitted stealing syringes from operating rooms that she would inject herself with then refill the syringes with sterile saline solution and put them back in the operating rooms. But a hepatitis C infection she contracted from using heroin caused her to spread the infectious disease to at least 15 surgical patients.
