Up to 150 individuals with current hepatitis C (HCV) will be recruited from mobile health clinics in rural South Carolina - sites will be selected based on HCV prevalence rates and lack of current HCV screening/treatment resources. NPs will provide HCV care through mobile health units. Participants will be randomized (1:1) to either mobile health clinic treatment as usual or virtual care coordination. Virtual care coordination designed to move people along HCV care cascade will be conducted by the Emocha smartphone platform - an adaptable platform designed by emocha to link patients to care. Using quantitative methods, associations between psychosocial factors such as homelessness, mental illness, provider mistrust, poor social support, high levels of shame and stigma with HCV outcomes including SVR will be examined. Investigators hypothesize that SVR rate among the HCV-infected individuals treated (and with follow-up SVR determination) will be 90% with the Clopper-Pearson 95% CI having a width of 13%.

Inclusion Criteria:

• Not previously treated with HCV direct-acting antiviral medications OR treatment-experienced and eligible for treatment with sofosbuvir/velpatasvir
• Age 18+
• Willing to be randomized to either emocha versus TAU arms
• Able to provide informed consent

Exclusion Criteria:

• Pregnant or breastfeeding

At time of randomization, participant is informed of study group assignment and provided instructions on use of app. Care provider is aware of group assignment as the provider is also using the platform to communicate with participants during course of treatment.
