This is a study to treat participants, with or without HIV, who are found to have been recently infected with the Hepatitis C virus (HCV). This known as acute HCV.
Purpose of this Study: People who are recently infected with HCV are often considered to have acute HCV. People with acute HCV have a good chance of being cured of the infection when they are treated with a combination of two drugs within the first 6 months of being infected. This study is being done to see if a shorter course of treatment will be effective if started early in the infection (Step 1). In case of failure with this shorter course of treatment, a longer and different treatment for HCV will be offered (Step 2).

Study Drugs: Glecaprevir/pibrentasvir (G/P) Fixed-dose Combination (FDC-single tablet) three pills by mouth once a day for 4 weeks (Step 1).

Duration of Study: Up to 28 weeks on Step 1 and up to an additional 40 weeks if on Step 2.
