Yes — you can get hepatitis C again after a cure. Direct-acting antiviral pills clear the virus in more than 95% of people WHO, but they don't leave behind immunity. Hepatitis C antibodies stay positive for life, so a past cure won't protect you from a new exposure. Only an RNA test can catch a reinfection.

What hepatitis C reinfection actually means
Reinfection is a brand-new hepatitis C infection that happens after you've already been cured of an earlier one. A relapse means the original virus was never fully cleared and rebounds after treatment ends, usually within weeks to a few months. Reinfection means the first infection resolved, you tested with no detectable virus, and then a separate exposure introduced the virus again. The distinction matters because relapse points to a treatment that fell short, while reinfection points to a fresh blood-to-blood exposure your cure did nothing to prevent.
Clearing hepatitis C, whether on your own or with treatment, does not make you immune. Your immune system doesn't build durable protection against the virus the way it does after some other infections. Someone cured last year can be reinfected this year if they're exposed again. For anyone with ongoing risk, retest every year rather than assuming the job is done.
Symptoms — and the silent reality
Most new hepatitis C infections cause no symptoms at all. When symptoms do appear, jaundice (yellowing of the skin and eyes from a buildup of bilirubin the liver can't process) shows up in only about 20–30% of people, and vaguer complaints like fatigue, poor appetite, abdominal pain, and dark urine in roughly 10–20% CDC. A reinfection behaves the same way the first time did. It's mostly quiet, and chronic hepatitis C can run 20 years or more with no specific symptoms before liver damage announces itself.
That silence means you can't rely on how you feel to know your status. If you were cured and feel completely fine, you could still be carrying a new infection. For a fuller picture of what early and chronic infection looks like, see our guide to hepatitis c symptoms in men and women.
How reinfection spreads
Hepatitis C spreads when blood from an infected person enters another person's bloodstream. In the US the main route is injection drug use — sharing needles, syringes, or any drug equipment that carries traces of blood. It can also pass from parent to baby at birth. There's no evidence it spreads through sharing utensils, hugging, kissing, holding hands, coughing, sneezing, or food and water.
Because reinfection requires a new blood exposure, the risk concentrates in people who continue the same activities that led to the first infection, most often ongoing injection drug use. Sexual transmission of hepatitis C is uncommon overall, but the risk rises with practices that can cause bleeding or mucosal trauma, and it's higher among people with hepatitis c and hiv coinfection. If you've had a recent possible exposure, our overview of when to test after exposure explains the timing.
How reinfection is tested — antibody won't tell you
Standard screening starts with an HCV antibody test, and if that's positive an automatic nucleic acid test (NAT) for HCV RNA confirms whether the virus is currently present CDC testing. For reinfection, the antibody test is useless on its own. Your antibodies stayed positive for life after your first infection, so they'll read positive whether or not you have a new one. To detect reinfection you need an RNA (viral) test that looks for the virus itself.
If you've been cured and have any continuing risk, get an HCV RNA test every year, and a viral test any time you have a new possible exposure. The blood draw is quick, results usually come back within a few days, and screening is often free or low-cost at health departments, Planned Parenthood, and Title X clinics. CDC recommends screening all adults at least once and during each pregnancy, and USPSTF gives one-time screening for adults aged 18–79 a Grade B recommendation USPSTF. Cured patients with risk need the RNA test repeated, not a one-and-done. Learn more about the right test in our guide to the hepatitis c test, or get tested now.
Treatment if you're reinfected
The treatment for reinfection is the same as for a first infection, and it works just as well. An 8–12-week course of oral direct-acting antiviral (DAA) pills cures more than 95% of people AASLD/IDSA, and that cure is durable, holding in over 99% of people followed five years. Common simplified regimens include glecaprevir/pibrentasvir taken for 8 weeks or sofosbuvir/velpatasvir taken for 12 weeks, and specialist guidance recommends treating essentially everyone with HCV, including people who've been cured before.
Being reinfected does not mean you've "used up" your one chance at cure. People can be treated and cured multiple times. The advice is the same as any course: take every dose for the full course even after you feel fine, and confirm cure with an RNA test after you finish. If injection drug use is the risk, pairing treatment with a syringe services program prevents the next round.
| Relapse | Reinfection | |
|---|---|---|
| What happened | Original virus was never fully cleared and rebounds | A new, separate infection after a confirmed cure |
| Typical timing | Usually within weeks to a few months of finishing treatment | Any time after cure, following a new exposure |
| How it's found | HCV RNA detectable after end-of-treatment clearance | HCV RNA turns positive again on routine or post-exposure retesting |
| Cause | Treatment didn't fully eradicate the virus | Fresh blood-to-blood exposure |
| Re-treatment works? | Yes | Yes — same DAA course, same high cure rate |
Complications if a reinfection goes untreated
A reinfection that's left alone carries the same long-term risks as any chronic hepatitis C. Over years, untreated infection can lead to cirrhosis (extensive scarring that stiffens the liver and blocks normal blood flow), liver cancer (hepatocellular carcinoma arising in the damaged liver), liver failure (the organ losing its ability to filter blood and make essential proteins), and death CDC clinical. These outcomes build slowly and silently, so by the time symptoms force the issue, the damage may be advanced. Catching reinfection early with an RNA test and re-treating prevents that trajectory.
Preventing reinfection after cure
There's no vaccine for hepatitis C, so prevention is about avoiding new blood exposures CDC prevention. The most effective steps target the routes that cause most infections:
- Don't share needles, syringes, or any drug-preparation equipment — this is the single biggest factor for reinfection in the US.
- Use syringe services programs, which supply sterile equipment and are a proven way to cut transmission.
- Don't share personal items that can carry blood, like razors or toothbrushes.
- Use condoms during higher-risk sex to lower the chance of transmission, especially relevant with HIV coinfection or partners who have hepatitis C.
- Retest with an HCV RNA test at least once a year if you have any ongoing risk — routine testing catches reinfection while it's still silent.
If you and a partner are both being treated or both at risk, ask your clinician about timing so you don't pass the virus back and forth. You can also compare testing providers to find convenient, affordable RNA retesting.
When to see a clinician
Book an RNA test if you've been cured of hepatitis C and have had any new blood exposure — shared injection equipment, a needlestick, or higher-risk sex — or if you simply have ongoing risk and it's been a year since your last viral test. See a clinician sooner if you develop jaundice, persistent fatigue, abdominal pain, or dark urine. A reinfection caught early is treatable, and clinics handle this every day.
