Treatment of Acute Hepatitis C at Initial Diagnosis with Confirmed Viremia
When acute hepatitis C is diagnosed and HCV RNA is quantifiable, current guidance calls for prompt antiviral treatment — not a period of watchful waiting. The clinical protocol covers regimen selection, genotyping decisions, and additional management steps relevant to this presentation.
Clinical scenario: Patient has an initial diagnosis of acute HCV infection with confirmed viremia on quantifiable RNA testing. Management decisions include whether genotyping is available, whether exposure to more than one genotype is a concern, and whether substance use was involved in acquisition. Counseling on hepatotoxic substances is part of the initial management plan.
Treatment approach — partial overview
The recommended strategy involves initiating direct-acting antiviral therapy at the time of initial diagnosis, without waiting for spontaneous resolution. When genotyping results are unavailable or multi-genotype exposure cannot be excluded, a pangenotypic regimen is the preferred choice. The complete protocol specifies regimen options, substance-use referral pathways, and additional counseling guidance beyond what is shown here.

- After the initial diagnosis of acute HCV with viremia (defined as quantifiable RNA), HCV treatment should be initiated without awaiting spontaneous resolution.
- Owing to high efficacy and safety, the same regimens that are recommended for chronic HCV infection are recommended for acute infection.
- Pangenotypic regimens are recommended if HCV genotyping is unavailable or if concern of exposure to more than 1 genotype exists.
- Counseling is recommended for patients with acute HCV infection to avoid hepatotoxic insults, including hepatotoxic drugs (eg, acetaminophen) and alcohol consumption, and to reduce the risk of HCV transmission to others.
- Acetaminophen and alcohol consumption should be avoided during acute HCV infection.
- Referral to an addiction medicine specialist is recommended for patients with acute HCV infection related to substance use.
