Hepatitis C

What is hepatitis C?

Hepatitis C is a liver disease that is caused by the hepatitis C virus. Hepatitis C is one type of hepatitis.

Hepatitis is a redness and swelling (inflammation) of the liver that sometimes causes lasting damage. The liver isn’t able to work the way it should.

Hepatitis C can be short-term (acute) or long-term (chronic):

  • Acute hepatitis C. This is a brief infection that lasts 6 months or less. It goes away because your body gets rid of the virus.

  • Chronic hepatitis C. This is a long-lasting infection that happens when your body can’t get rid of the virus. It causes long-term liver damage.

Scientific advancements in treatment options have improved rapidly over the past few years, offering patients a better chance for clearing the virus.

Hepatitis C is considered "cured" if the virus is not detected when measured with a blood test three months after the completion of treatment.

What causes hepatitis C?

Hepatitis C is caused by infection from the hepatitis C virus. Like other viruses, hepatitis C is passed from person to person. This happens when you have contact with an infected person’s blood.

You may get the virus if you:

  • Share needles used for illegal drugs.

  • Have sex with someone who has hepatitis C

 Babies may also get the disease if their mother has the hepatitis C virus.

Who is at risk for hepatitis C?

Anyone can get hepatitis C by having contact with the blood of someone who is infected with the virus.

But some people are at higher risk for the disease. They include:

  • Children born to mothers who are infected with hepatitis C

  • People who have jobs that involve contact with human blood, body fluids, or needles

  • People who have a blood-clotting disorder such as hemophilia, and received clotting factors before 1987

  • People who need dialysis treatment for kidney failure

  • People who had blood transfusions, blood products, or organ transplants before the early 1990s

  • People who take IV or intravenous drugs

  • People who have sex with an infected partner

  • People with HIV

What are the symptoms of hepatitis C?

Many people with hepatitis C don’t know they have it. In most cases people who are infected with hepatitis C may not show any symptoms for several years.

It is still possible to pass the virus to someone else if you have hepatitis C but do not have any symptoms.  

Each person’s symptoms may vary. Some of the most common symptoms include:

  • Loss of appetite

  • Extreme tiredness (fatigue)

  • Nausea and vomiting

  • Stomach pain

  • Yellowing of the skin and eyes (jaundice)

  • Fever

  • Diarrhea

  • Dark yellow urine

  • Light-colored stools

  • Muscle and joint pain

Hepatitis C symptoms may look like other health problems. Always see your healthcare provider to be sure.

How is hepatitis C diagnosed?

Your healthcare provider will give you a physical exam and ask about your past health. He or she will also do a blood test to see if you have hepatitis C.

If your provider thinks you have long-term (chronic) hepatitis C, he or she may take a small tissue sample (biopsy) from your liver with a needle. The sample is checked under a microscope to see what type of liver disease you have and how severe it is.

How is hepatitis C treated?

Hepatitis C is not treated unless it becomes a long-term or chronic infection. If so, antiviral medications are used to try to slow down or stop the virus from hurting your liver. Your symptoms will be closely watched and managed as needed.

If severe liver damage takes place, you may need a liver transplant.ding:

Treatment for hepatitis C depends on several factors, including:


  • How much virus is in your body

  • The genotype or strain of hepatitis C you have

  • If you have liver damage, such as cirrhosis

  • What other health conditions you have

  • Your response to any previous treatments for hepatitis C


Discuss the risks and benefits of treatment options with your provider.

What are the complications of hepatitis C?

Many people with hepatitis C develop chronic liver disease. You could need a liver transplant. Hepatitis C is the most common cause of liver transplants in the U.S.

Liver failure can lead to death.

The risk of liver cancer is higher in people with hepatitis C.

What can I do to prevent hepatitis C?

There is no vaccine to prevent hepatitis C. But you can protect yourself and others from getting infected by:

  • Making sure any tattoos or body piercings are done with sterile tools

  • Not sharing needles and other drug materials

  • Not sharing toothbrushes or razors

  • Not touching another person’s blood unless you wear gloves

  • Abstaining from sexual intercourse. Abstinence is the only sure method of avoiding sexually-transmitted hepatitis. A person who is infected with hepatitis can transmit the disease to a sexual partner. If a hepatitis-infected person decides to engage in sexual intercourse, public health agencies recommend the use of a prophylactic to decrease the possibility of transmitting hepatitis to a sexual partner.
