Harrington Case: Link of HIV to Practice Deemed 'Inconclusive'

Tulsa health officials stated Thursday morning that genetic tests on HIV specimens from former patients of Scott Harrington were deemed inconclusive for potential connection to his practice.

A statement was released from the Tulsa Health Department after specimens were taken from three or four of the patients that tested positive for HIV to determine if the source of infections was related to Harrington's clinic. The Centers of Disease Control assisted in the investigation.

Previous reports from KTUL and the health department stated that officials were able to confirm the transmission of hepatitis C at his practice. This was reportedly the first documented transmission of the virus associated with a dental setting in the U.S.

Health inspectors shut down Harrington's clinic March 28 after finding unsanitary conditions. A 17-count complaint filed by the state said officials found rusty instruments, potentially contaminated drug vials and improper use of a machine designed to sterilize tools at Harrington's offices

The investigation is continuing and Harrington is cooperating with the probe.
