It is important to keep in mind that the hepatitis C virus, or HCV, can affect you much differently than it does someone else. For example, some people have very bad hepatitis C symptoms and cirrhosis after many years of having the disease, while others have very few scars. Of the people who have the virus for 20 years, approximately 20 percent (1 out of 5 patients) will have severe scarring, or cirrhosis, in their liver. Once cirrhosis develops, the person is at risk for many life-threatening complications of hepatitis C liver disease.
