A medical technician who was charged last week with causing a hepatitis C outbreak in New Hampshire was fired from a hospital in Arizona in April 2010, an official at the hospital said. The technician, David Kwiatkowski, was fired after being found unresponsive in a men’s locker room with syringes and needles; tests found cocaine and marijuana in his system, said the official, Monica Bowman, chief executive of Arizona Heart Hospital. Mr. Kwiatkowski, 33, is accused of stealing anesthetic drugs from Exeter Hospital in New Hampshire and contaminating syringes. His strain of hepatitis C has been diagnosed in 30 patients, and testing has been recommended for about 4,700 people in New Hampshire alone. Officials are still determining who should be tested elsewhere. They have confirmed that Mr. Kwiatkowski also worked in Georgia, Kansas, Maryland, Michigan, New York and Pennsylvania before being hired in New Hampshire.
