Hepatitis C virus
Acute and chronic hepatitis C
The short answer
Hepatitis C can remain symptomless for years. Current antiviral treatment can cure most people; linking diagnosis to appropriate care matters.
Transmission and timing
Transmission mainly involves infected blood, including shared needles or contaminated equipment. Hugging, sharing meals and being in the same room are not usual routes.
CDC ↗Symptoms and risk groups
Fatigue, nausea, dark urine or jaundice may develop, but symptoms may be absent. Normal liver enzymes alone are not sufficient to exclude infection.
CDC ↗CDC ↗When to seek help
Seek assessment for new jaundice. In someone with cirrhosis, vomiting blood, black stools or sudden confusion is an emergency, even during antiviral treatment.
NHS ↗NHS ↗For life-threatening symptoms, severe breathing difficulty or altered consciousness, call your local emergency number (112 in Türkiye).
What does the test show?
A positive anti-HCV result can reflect past or current infection. HCV RNA is needed to assess current infection; negative RNA usually means no current infection.
CDC ↗Care and treatment approach
Direct-acting antivirals are central to treatment. Drug interactions, stage of liver disease and other infections inform an individualized plan.
AASLD / IDSA ↗Prevention and everyday life
There is no hepatitis C vaccine. Sterile equipment and avoiding blood exposure matter. Cure does not prevent reinfection, so prevention remains important.
WHO ↗Special situations and risk groups
Testing and treatment differ in pregnancy and childhood. A baby born to a mother with HCV needs an age-appropriate follow-up plan with a paediatric clinician.
CDC ↗A common misunderstanding
Antibodies may remain positive after successful treatment. Do not measure cure by antibody disappearance; select the appropriate test after a new exposure.
CDC ↗Clinical assessment note
Complete reactive antibody testing with RNA assessment and linkage to care. An early negative antibody result after recent exposure can mislead; plan retesting in context.
CDC ↗Bring a question to your appointment
What is my RNA result, and which follow-up and reinfection-prevention steps continue after treatment?
International evidence, local decisions
Each source’s country is identified. Vaccine access, reimbursement, isolation and reporting rules vary. Use current guidance and your clinician’s advice in your country; English does not imply UK or US eligibility.
