Hepatitis C is an infection of the liver. It's caused by the hepatitis C virus. About 3.2 million people in the U.S. have hepatitis C. But because the virus causes so few symptoms, most of them don't know they have the disease.
There are many types of hepatitis C virus. The most common in the U.S. is type 1. No type is more serious than any other, but they respond differently to treatment.

You can get a blood test to see if you have the hepatitis C virus.
Are There Any Long-Term Effects of Hepatitis C?
Yes. In people who have hepatitis C, 75% to 85% may develop a long-term infection. Hepatitis C is one of the top reasons that people need a liver transplant.
What's the Treatment for Hepatitis C?
If you have hepatitis C and show signs of liver damage, your doctor will suggest medication.
Treatment for hepatitis C keeps changing quickly. Until recently, most people with hepatitis C had to take a blend of shots and pills that often came with some unpleasant side effects. The standard treatment was usually shots of interferon plus other drugs -- usually ribavirin and either Incivek (telaprevir) or Victrelis (boceprevir).
But the newer drugs Olysio (simeprevir) and Solvadi (sofosbuvir) cure more people in less time with fewer and milder side effects. The drugs are taken together with interferon and ribavirin. Doctors hope that soon more people will be able to stop taking interferon, the treatment that causes so many side effects.
Side Effects of Hepatitis C Treatment
Side effects of treatment for hepatitis C include:
Low blood counts
Also, the FDA has said it has received reports of a serious skin rash from combination treatment with Incivek, which has led to several deaths.
