Hepatitis C and HIV coinfection means a person carries both the hepatitis C virus (HCV) and HIV at the same time. The two share blood and sexual routes, so they often travel together. Coinfection speeds liver damage from hepatitis C, but HCV is now curable with oral pills in most people CDC.

What hepatitis C and HIV coinfection actually is
Hepatitis C is a liver infection caused by HCV, which spreads when blood from an infected person enters another person's bloodstream. The first six months after exposure is called acute infection; most people who catch it never clear the virus and develop a chronic, lifelong infection instead. Unlike hepatitis B, hepatitis C is curable, and treatment works in more than 95% of people CDC clinical.
HIV is a separate virus that weakens the immune system. When someone lives with both, the term is coinfection. The two viruses share the same paths into the body: injecting drug equipment and, increasingly, certain higher-risk sexual contact. HIV also changes how hepatitis C behaves, raising the amount of HCV in the blood and pushing the liver toward scarring faster. Clinicians treat coinfection with urgency rather than watching and waiting.
Symptoms — and the silent reality
Most hepatitis C infections cause no symptoms at all. Yellowing of the skin and eyes (jaundice) shows up in only about 20–30% of acute infections, and vague complaints like fatigue, poor appetite, belly pain, and dark urine in only about 10–20%. Chronic hepatitis C can sit quietly for 20 years or more before it announces itself, often only once the liver is already scarred.
When acute symptoms do appear, the average time from exposure to onset is 2–12 weeks, with a range of 2 to 26 weeks. HIV and hepatitis C produce overlapping, nonspecific complaints, and HIV can blunt the antibody response, so testing is the only reliable way to know your status. For a fuller breakdown of what to watch for, see our guide to hepatitis c symptoms in men and women.
How coinfection spreads
The main route for hepatitis C in the US is injection drug use, meaning sharing needles, syringes, or other drug equipment, which also transmits HIV, so the two often arrive by the same path. Hepatitis C can pass from a parent to a baby at birth as well.
Sexual transmission of HCV is normally inefficient, but the picture shifts in coinfection. Among people living with HIV, particularly men who have sex with men, hepatitis C does spread sexually during higher-risk contact that involves blood exposure. There's no evidence hepatitis C passes through sharing utensils, hugging, kissing, holding hands, coughing, sneezing, or food and water CDC prevention. If you've had a possible exposure, our guide on when to test after exposure explains the timing.
How it's tested
Testing starts with an HCV antibody test, which checks whether your body has ever responded to the virus. If that's positive, the lab automatically runs a nucleic acid test (NAT) for HCV RNA to confirm whether the virus is currently active, since antibodies alone can't tell a past, cleared infection from a current one CDC testing. In coinfection this RNA step matters more, since HIV can delay or weaken the antibody response and make the screening test harder to read.
The CDC recommends screening all adults 18 and older at least once, and screening all pregnant people during each pregnancy; the USPSTF gives a Grade B recommendation for one-time screening of adults aged 18 to 79 USPSTF. Anyone living with HIV should be screened for hepatitis C and, with ongoing risk, retested regularly.
Testing is simple: a blood draw, with results usually back within a few days, and it's free or low-cost at health departments, Planned Parenthood, and Title X clinics. You can review your options for a hepatitis c test, or get tested and compare testing providers to find the right fit.
Treatment when you have both
Hepatitis C is curable for almost everyone. Direct-acting antiviral (DAA) pills cure more than 95% of people, usually over an 8–12-week course, and the cure holds in over 99% of people followed five years AASLD/IDSA. The simplified regimens are glecaprevir/pibrentasvir for 8 weeks or sofosbuvir/velpatasvir for 12 weeks. Specialist guidance now recommends treating essentially everyone with HCV, not just advanced cases.
Coinfection adds the issue of drug interactions. Some HIV antiretrovirals and some hepatitis C DAAs interact, so the team checks your full medication list and may adjust the HIV regimen for the treatment window. Have both conditions managed together rather than in separate silos. Finish the entire course even once you feel well, and keep taking your HIV medication throughout.
| Feature | Hepatitis C alone | HCV in HIV coinfection |
|---|---|---|
| Liver scarring | Typically slow, over decades | Tends to progress faster |
| Antibody test reliability | Usually clear | May be delayed or blunted by HIV |
| Cure rate with DAAs | More than 95% | Comparably high |
| Main treatment concern | Adherence to full course | Drug interactions with HIV meds |
Complications if it's left untreated
Untreated chronic hepatitis C can lead to cirrhosis (heavy, permanent scarring that stiffens the liver and blocks normal blood flow), liver cancer (hepatocellular carcinoma, which often arises in an already-cirrhotic liver), liver failure (when the organ can no longer clear toxins or make essential proteins), and death. HIV accelerates this path, which raises the stakes in coinfection.
Curing hepatitis C lowers the risk of these outcomes substantially, and it's reachable for almost everyone, including people living with HIV.
Prevention in practice
There is no vaccine for hepatitis C, so prevention is about blocking blood-to-blood and higher-risk sexual exposure. Don't share needles, syringes, or personal items like razors or toothbrushes; use syringe services programs if you inject; and use condoms during higher-risk sex to reduce transmission.
- Use condoms every time during higher-risk sex; they lower the chance of passing HCV and HIV both.
- Never share injection equipment, and access syringe services programs where available.
- Keep razors and toothbrushes personal, since they can carry traces of blood.
- Test routinely to catch an infection that has no symptoms; it's a normal part of staying healthy with HIV.
When to see a clinician
See a clinician if you live with HIV and have never been screened for hepatitis C, if you've shared injection equipment, or if you've had a recent higher-risk sexual exposure. By the time hepatitis C causes symptoms, the liver may already be damaged, so don't wait for them. This diagnosis is common and treatable, and clinics handle it daily. The sooner you test, the sooner a cure is on the table.
