Teresa Wilcox is devastated by the diagnosis. She tells Dr. Horowitz that she’s never had a blood transfusion or been exposed to blood products. She has never used IV drugs, but did inhale cocaine once or twice at parties in college. She has had several sexual partners, and the only time she has come into contact with any kind of needles was when she had her naval pierced 6 months ago. How, most likely, did Terri contract hepatitis C?
