The Hepatitis C outbreak at a New Hampshire hospital has been linked to former worker David Matthew Kwiatkowski, who is thought to have infected at least 30 people during his employment as a medical technician in the cardiac catheterization lab. Additionally, Kwiatkowski is believed to have stolen an undisclosed amount of Fentanyl, a controlled substance which is reportedly more powerful than morphine.

Kevin Callahan, president and CEO of Exeter Hospital, recently released a statement to address the matter. He explained, “It is deeply disturbing that the alleged callous acts of one individual can have such an impact on so many innocent lives. As a result of his alleged actions, people in our community, who in many cases are the friends and neighbors of the 2,300 people who work here, now face the challenge of a potentially chronic disease.”

Kwiatkowski’s co-workers at the hospital stated the man frequently acted peculiar, as if he was up to something suspicious. During CCL procedures, he would often leave abruptly, which led some witnesses to theorize that he was on some sort of drug. One co-worker even stated that Kwiatkowski was once spotted on-duty with an extremely red face and foam around the corners of his mouth.

“The evidence gathered to date points irrefutably to Kwiatkowski as the source of the hepatitis C outbreak at Exeter Hospital. With his arrest, we have eliminated the menace this ‘serial infector’ posed to public health and safety,” explained United States Attorney John P. Kacavas.

Although Kwiatkowski stated he discovered he was carrying the virus in May of 2012, investigators eventually learned the truth: he actually tested positive for hepatitis C in June of 2010. What makes this story even more alarming is the fact that Kwiatkowski was once a traveling medical technician whose job took him to over six different states. No word yet if any of the other areas he visited have experienced the same problems.
