The goal of this non-randomised, quasi-experimental, prospective comparative trial is to trial simplified care pathways for hepatitis C testing and treatment for people who inject drugs in Armenia, Georgia, and Tanzania. The main questions it aims to answer are: 1. What is the feasibility of implementing a hepatitis C simplified care and same-day treatment care model in community and harm reduction settings in the three study countries? 2. Does a same-day treatment initiation model involving only POC antibody tests (with a shortened read-time) increase hepatitis C treatment uptake and SVR12 outcome (cure) among people who inject drugs compared with a simplified care model involving POC antibody followed by a confirmatory RNA test? 3. What is the comparative cost-effectiveness between a same-day antibody only hepatitis C testing and treatment model and the simplified care model (POC antibody/confirmatory RNA test) model? Participants will: * be enrolled in a new simplified model of care in each country (Arm 1). After the enrolment target is met for Arm 1 (approx. 3-9 months into implementation) new participants will be enrolled into a same-day treatment trial, using presumptive treatment after a reactive POC test result at shortened read-time (5minutes) (Arm 2) * if in Arm 1, participants will commence SOF-VEL DAA treatment after receiving an RNA test to confirm current hepatitis C infection. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. * if in Arm 2, participants will begin SOF-VEL DAA treatment on the same day as the 5 minute RDT testing. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. Researchers will compare cure and participant retention rates between the two groups.

We will conduct a study to trial a new, simplified, and lower cost clinical pathway and determine its feasibility, effectiveness, cost-effectiveness and acceptability in Armenia, Georgia, and Tanzania. This is a non-randomised, quasi-experimental, prospective comparative trial with approximately 350 participants initiated onto hepatitis C treatment in each arm. Arm one is a simplified care model (following global guidance) with hepatitis C treatment commencing after a rapid hepatitis C antibody test and a confirmatory positive hepatitis C ribonucleic acid (RNA) test. Arm two will involve same day treatment commencement following a positive rapid antibody test without confirmatory RNA testing prior to treatment initiation (RNA testing will be completed after treatment is provided). In arm two, the decision to treat will be based on the result of an early read time (\< 5 mins) of a rapid antibody test which previous research findings suggest correlates strongly with a hepatitis C RNA positive test result. All positive participants will be treated with sofosbuvir (400mg) and velpatasvir (100mg), self-administered orally once per day for 12 weeks. Hepatitis C cure will be assessed by sustained virological response (SVR) laboratory testing. The first primary outcome is feasibility, measured throughout the care cascade. Primary outcomes compared across the two arms will be the proportion of participants 1) commencing treatment and 2) achieving SVR. Test concordance and validity of the early read time will be assessed against laboratory RNA test results (which will also guide decisions to continue or cease treatment in Arm 2). A mixed effects model will be used to assess study outcomes and infectious diseases modelling will determine cost-effectiveness. The acceptability and feasibility of the models will be assessed through thematic analysis of participant and practitioner interviews, and site assessments.
