On Monday, health officials confirmed that Canton native David Kwiatkowski worked in at least six Michigan hospitals from 2003 to 2007, according to the Associated Press.
But the Michigan Department of Community Health told AP it has not uncovered evidence that Kwiatkowski was infected with hepatitis C while working at the Michigan facilities, as was the case at Exeter Hospital.
It's the latest information to be released as health officials attempt to piece together a timeline of when and where Kwiatkowski worked to help determine what patients might need to be tested for hepatitis C.
Here is a timeline showing what investigators have learned so far about Kwiatkowski's employment history, courtesy of CNN:
