The purpose of this study is to evaluate the response the subject had after they have completed participation in a Merck-sponsored treatment study for hepatitis C.

This study is a long term follow-up Registry study. No study medication will be administered.
Subject participation in this research study is expected to last 3 to 5 years depending on which parent study they participated in initially.
