A spokesman for The Johns Hopkins Hospital says a man accused of causing a hepatitis C outbreak in New Hampshire previously worked at the Baltimore hospital.
Spokesman Gary Stephenson says David Kwiatkowski worked in the cardiac catheterization lab there for six months starting in July 2009. He says Kwiatkowski has worked at at least three other Maryland hospitals as well.
Kwiatkowski, a traveling lab technician, was charged Thursday with federal drug crimes. He's accused of stealing anesthetic drugs from Exeter Hospital, injecting himself and contaminating syringes that were later used on patients. Thirty patients have been diagnosed with hepatitis C since the investigation began in mid-May.
Authorities say Kwiatkowski has worked in at least six states since 2007, but they not have publicly identified the others.
