Incorrect testing and communication delays are being blamed for a hepatitis C infection at Children's Hospital Boston.
A child received a piece of heart tissue in September without doctors knowing it came from a donor who had hepatitis C.
Dr. Matthew Kuehnert, with the Centers for Disease Control, says the problem was with an out-of-state tissue bank.
"If appropriate and accurate testing had been used, then these cases would have been prevented," he said. "In this case, there was a laboratory error which resulted in a test being read as negative when it was positive."
In a statement, Children's Hospital says the child doesn't have symptoms, and that the situation is "unfortunate." It says it's working to develop a treatment plan for the child.
Two people in other states also were infected with the virus, after receiving the donor's kidneys from Kentucky.
