In March, state and local health officials began notifying approximately 7,000 of Harrington's former patients they may have been exposed to HIV, hepatitis B and hepatitis C. An investigation into the oral surgeon uncovered improper sterilization practices.
The investigation began after one of Harrington's patients tested positive for hepatitis.
