Hepatitis C virus (HCV) is a virus that can damage the liver.
About 2% of Americans are infected with HCV. Hepatitis C, the liver disease caused
by HCV, is a common worldwide problem and leads to 12,000 deaths each year in the United States. You can be
infected with the virus and not know you have it. Hepatitis C virus spreads by contact with blood from an infected individual.
A simple blood test can show if you are infected with HCV. Since 1992, all blood donations have been tested for HCV.
About three quarters of persons infected with HCV develop chronic (long-term) hepatitis.
Fortunately, only about one quarter develop progressive, irreversible liver damage. In those
cases, liver tissue is gradually destroyed over time and replaced with scar tissue (cirrhosis).
the presence of cirrhosis, liver failure and liver cancer can occur. The May 14, 2003, issue of JAMA includes an
article about hepatitis C.
Blood transfusion or organ transplant before 1992
Exposure to infected blood
Illegal drug use (contaminated needles or other drug equipment)
(usually from food or feces contaminated by infected individuals)
(from infected blood, sexual contact, or mother-to-baby transmission)
Hepatitis D, E, and G
(usually from infected blood or blood products)
Alcohol use should be completely stopped because it greatly increases the risk for cirrhosis
Interferon (stops the virus from making more copies of itself)
Ribavirin (an antiviral medication)
Liver transplantation (if the patient 's liver is no longer functioning adequately)
Elimination of HCV from the body is possible, but the side effects of treatment can be serious.
Your doctor may suggest that mild cases of hepatitis C infection should be watched carefully
and treatment started if the disease begins to progress. Medical research studies are ongoing to
help answer questions about hepatitis C treatment. Transplantation of a new liver to replace the liver
damaged by hepatitis C is an option for treatment of advanced cirrhosis or early liver cancer. Transplantation is
limited by the number of organs available for donation. Liver transplantation is major surgery, and lifelong medications
are required after the transplant to prevent the body from rejecting the transplanted liver.
