CDPHE spokesman Mark Salley says that the lab findings cannot be definitely traced back to unsafe practices at Stein's office, and that no one can be sure how many people have really been infected.
"We don't know if it is three out of a hundred, three out of a thousand," he notes. "We only know of positive test results."
Stein, who is also accused of prescription fraud, entered into a cessation of practice agreement with the Colorado State Board of Dental Examiners in June of last year, and his offices have been closed. According to 9News, Stein moved out of his home one day before news broke that the CDPHE was investigating his practice.
The CDPHE urges people who may have received intravenous medication from Stein from 1999 to 2011 to contact their health care provider and get tested HIV, hepatitis B and hepatitis C immediately.
