What is hepatitis C?
Hepatitis is inflammation of the liver. Inflammation is swelling that happens when tissues of the body are injured or infected. Inflammation can damage organs.
There are different types of hepatitis. One type, hepatitis C, is caused by the hepatitis C virus (HCV). Hepatitis C can range from a mild illness lasting a few weeks to a serious, lifelong illness.
Hepatitis C can be acute or chronic:
Acute hepatitis C is a short-term infection. The symptoms can last up to 6 months. Sometimes your body is able to fight off the infection and the virus goes away. But for most people, an acute infection leads to chronic infection.
Chronic hepatitis C is a long-lasting infection. If it is not treated, it can last for a lifetime and cause serious health problems, including liver damage, cirrhosis (scarring of the liver), liver cancer, and even death.
How is hepatitis C spread?
Hepatitis C spreads through contact with the blood of someone who has HCV. This contact may be through
Sharing drug needles or other drug materials with someone who has HCV. In the United States, this is the most common way that people get hepatitis C.
Getting an accidental stick with a needle that was used on someone who has HCV. This can happen in health care settings.
Being tattooed or pierced with tools or inks that were not sterilized after being used on someone who has HCV
Having contact with the blood or open sores of someone who has HCV
Sharing personal care items that may have come in contact with another person's blood, such as razors or toothbrushes
Being born to a mother with HCV
Having unprotected sex with someone who has HCV
Before 1992, hepatitis C was also commonly spread through blood transfusions and organ transplants. Since then, there has been routine testing of the U.S. blood supply for HCV. It is now very rare for someone to get HCV this way.
Who is at risk for hepatitis C?
You are more likely to get hepatitis C if you
Have injected drugs
Had a blood transfusion or organ transplant before July 1992
Have hemophilia and received clotting factor before 1987
Have been on kidney dialysis
Were born between 1945 and 1965
Have abnormal liver tests or liver disease
Have been in contact with blood or infected needles at work
Have had tattoos or body piercings
Have worked or lived in a prison
Were born to a mother with hepatitis C
Have HIV/AIDS
Have had more than one sex partner in the last 6 months
Have had a sexually transmitted disease
Are a man who has had sex with men
If you are at high risk for hepatitis C, your health care provider will likely recommend that you get tested for it.
What are the symptoms of hepatitis C?
Most people with hepatitis C have no symptoms. Some people with acute hepatitis C do have symptoms within 1 to 3 months after they are exposed to the virus. These symptoms may include
Dark yellow urine
Fatigue
Fever
Gray- or clay-colored stools
Joint pain
Loss of appetite
Nausea and/or vomiting
Pain in your abdomen
Jaundice (yellowish eyes and skin)
If you have chronic hepatitis C, you probably will not have symptoms until it causes complications. This can happen decades after you were infected. For this reason, hepatitis C screening is important, even if you have no symptoms.
What other problems can hepatitis C cause?
Without treatment, hepatitis C may lead to cirrhosis, liver failure, and liver cancer. Early diagnosis and treatment of hepatitis C can prevent these complications.
How is hepatitis C diagnosed?
Health care providers diagnose hepatitis C based on your medical history, a physical exam, and blood tests.
If you do have hepatitis C, you may need additional tests to check for liver damage. These tests may include other blood tests, an ultrasound of the liver, and a liver biopsy.
What are the treatments for hepatitis C?
Treatment for hepatitis C is with antiviral medicines. They can cure the disease in most cases.
If you have acute hepatitis C, your health care provider may wait to see if your infection becomes chronic before starting treatment.
If your hepatitis C causes cirrhosis, you should see a doctor who specializes in liver diseases. Treatments for health problems related to cirrhosis include medicines, surgery, and other medical procedures. If your hepatitis C leads to liver failure or liver cancer, you may need a liver transplant.
Can hepatitis C be prevented?
There is no vaccine for hepatitis C. But you can help protect yourself from hepatitis C infection by
Not sharing drug needles or other drug materials
Wearing gloves if you have to touch another person's blood or open sores
Making sure your tattoo artist or body piercer uses sterile tools and unopened ink
Not sharing personal items such toothbrushes, razors, or nail clippers
Using a condom when you have sex
