ABSTRACT
Imagine that you are a physician in Norman, Oklahoma, in 2002. You have noticed an increase in the number of patients you suspect of having hepatitis C. Your patients lack the usual risk factors for hepatitis C (illicit drug use, piercings or tattoos received in unclean conditions, previous clotting problems, history of dialysis, etc.). As you puzzle over the mystery, you realize that these patients have one thing in common: they received intravenous pain medication at a certain pain management clinic.
