Hepatitis is treatable and curable, and chances of a successful cure depend on how chronic the symptoms are and how much damage has already been done, according to WebMD. The development of the antiviral drugs interferon and ribavirin during the 1990s greatly increased the chances of curability.
Mayo Clinic reports that not everyone who is diagnosed with hepatitis C requires treatment, but it is still important to monitor the liver for damage. There is no preventative vaccine for hepatitis C, but doctors generally recommend getting the A and B shots after the C diagnosis to prevent elevated risks for liver damage. When the liver is too badly damaged, a liver transplant can work as a temporary cure, but medication must continue to prevent recurrence.
