What causes hepatitis C?
The hepatitis C virus causes hepatitis C. Viruses are germs that can cause sickness. For example, the flu is caused by a virus. People can pass viruses to each other.

Who gets hepatitis C?
Anyone can get hepatitis C, but some people are at higher risk, including
- people who were born to a mother with hepatitis C
- people who have had more than one sex partner in the last 6 months or have a history of sexually transmitted disease
- people who had a blood transfusion or organ transplant before July 1992
- people with hemophilia who received blood products before 1987
- people who have used illegal injection drugs

How could I get hepatitis C?
You could get hepatitis C through contact with an infected person’s blood.
You could get hepatitis C from
- being born to a mother with hepatitis C
- having sex with an infected person
- being tattooed or pierced with unsterilized tools that were used on an infected person
- getting an accidental needle stick with a needle that was used on an infected person
- using an infected person’s razor or toothbrush
- sharing drug needles with an infected person
You could get hepatitis C by sharing drug needles with an infected person.
You cannot get hepatitis C from
- shaking hands with an infected person
- hugging an infected person
- sitting next to an infected person

What are the symptoms of hepatitis C?
Most people have no symptoms until the virus causes liver damage, which can take 10 or more years to happen. Others have one or more of the following symptoms:
- yellowish eyes and skin, called jaundice
- a longer than usual amount of time for bleeding to stop
- swollen stomach or ankles
- easy bruising
- tiredness
- upset stomach
- fever
- loss of appetite
- diarrhea
- light-colored stools
- dark yellow urine
A doctor can test you for hepatitis C.

What is chronic hepatitis C?
Hepatitis C is chronic when the body can’t get rid of the hepatitis C virus. Although some people clear the virus from their bodies in a few months, most hepatitis C infections become chronic. Without treatment, chronic hepatitis C can cause scarring of the liver, called cirrhosis; liver cancer; and liver failure.
Symptoms of cirrhosis include
- yellowish eyes and skin, called jaundice
- a longer than usual amount of time for bleeding to stop
- swollen stomach or ankles
- tiredness
- nausea
- weakness
- loss of appetite
- weight loss
- spiderlike blood vessels, called spider angiomas, that develop on the skin

How is hepatitis C diagnosed?
Hepatitis C is diagnosed through blood tests, which can also show if you have chronic hepatitis C or another type of hepatitis. Your doctor may suggest getting a liver biopsy if chronic hepatitis C is suspected. A liver biopsy is a test for liver damage. The doctor uses a needle to remove a tiny piece of liver, which is then looked at with a microscope.
Blood is drawn for hepatitis C testing.

How is hepatitis C treated?
Hepatitis C is not treated unless it becomes chronic. Chronic hepatitis C is treated with drugs that slow or stop the virus from damaging the liver.
Drugs for the Treatment of Chronic Hepatitis C
Chronic hepatitis C is most often treated with the drug combination peginterferon and ribavirin, which attacks the hepatitis C virus. Peginterferon is taken through weekly shots and ribavirin is taken daily by mouth. Treatment lasts from 24 to 48 weeks.Liver Transplantation
A liver transplant may be necessary if chronic hepatitis C causes liver failure. Liver transplantation surgery replaces a failed liver with a healthy one from a donor. Drug treatment often must continue because hepatitis C usually comes back after surgery.
Hepatitis C is treated with pills and shots of medicine.

How can I avoid getting hepatitis C?
You can protect yourself and others from hepatitis C if you
- do not share drug needles
- wear gloves if you have to touch another person’s blood
- use a condom during sex
- do not borrow another person’s toothbrush, razor, or anything else that could have blood on it
- make sure any tattoos or body piercings you get are done with sterile tools
- do not donate blood or blood products if you have hepatitis C
Do not share needles if you inject drugs.

What should I do if I think I have been exposed to the hepatitis C virus?
See your doctor and get tested if you are at higher risk of getting hepatitis C or if you think you were exposed to the hepatitis C virus. Many people do not know they are infected. Early diagnosis and treatment can help prevent liver damage.

Hope through Research
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) conducts and supports basic and clinical research into many digestive disorders, including hepatitis C.
Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research. For information about current studies, visit www.ClinicalTrials.gov.
