Hepatitis C: Symptoms, Testing, Treatment & Prevention

Hepatitis C is a virus that attacks the liver. Many people don’t feel sick at first, so it can go unnoticed for years. Left unchecked, it can cause scarring, reduced liver function, or even liver cancer. The good news: modern tests and treatments make cure possible for most people.

How it spreads and who should get tested

The virus spreads mainly through blood-to-blood contact. Common ways include sharing needles or syringes, receiving contaminated blood products in places with poor screening, and less often through unprotected sex when blood is present. Many people born before widespread blood screening, or anyone with past injection drug use, should get tested. Pregnant people and people with abnormal liver tests are also often screened.

Testing: what to expect

Testing usually starts with an antibody test. If that’s positive, a follow-up RNA test checks for active infection. Antibody tests tell if you were ever exposed; RNA tests show if the virus is still in your blood. Results are fast in many clinics, and you don’t always need a specialist to start this process.

Treatment today is much easier than it used to be. Direct-acting antivirals (DAAs) are oral pills taken for 8–12 weeks in most cases and cure more than 95% of people. Some regimens work for all major virus types, while others target specific genotypes. Your doctor will pick the best option based on your health, liver condition, and any other medicines you take.

Before treatment, you may get blood tests and a scan or noninvasive fibrosis test to see how much liver damage exists. After successful treatment, most people need periodic follow-up to check liver health and screen for cancer if scarring (cirrhosis) was present.

Small changes at home make a big difference. Avoid alcohol, which speeds liver damage. Stay up to date on vaccines like hepatitis A and B. Keep a healthy weight, move regularly, and manage other conditions—like diabetes—that stress the liver.

Prevention matters. Never share needles, razors, or toothbrushes that might have blood on them. If you’re in healthcare or tattooing, follow strict safety rules. Use barrier protection during sex when blood could be involved. Many harm-reduction programs offer clean supplies and testing—use them.

If you think you were exposed or have unexplained fatigue, jaundice, or stomach pain, talk to a clinician and ask for HCV testing. Treatment works best when started early, and cured people greatly reduce their risk of liver complications. Got questions about testing, treatment options, or living with hepatitis C?
