Hepatitis C is a liver disease that ranges in severity from a mild illness, lasting a few weeks, to a serious, lifelong illness. The HCV virus enters the bloodstream and replicates in the liver cells, damaging them in the process. If left untreated, inflammation in the liver replaces healthy cells with scar tissue and the risk of cirrhosis and liver cancer increases.

There is no vaccine for HCV, however treatment stops the virus from replicating in the body. Cure rates are about 95% and side effects are minimal.
