Hepatitis C is an infectious disease of the liver. Worldwide, health experts estimate that 180 million people have chronic hepatitis C, with more than 4 million of those cases in the United States.

Hepatitis C, like all forms of hepatitis, can damage the liver. Of people infected, 55 to 85 percent will develop chronic infection, and 75 percent of those with chronic infection will develop chronic liver disease.
