The hepatitis C virus (HCV) is transmitted by blood-to-blood contact. Hepatitis C is currently the leading cause of chronic liver disease in the U.S. and the most common indication for adult liver transplantation. HCV is known cause of liver cancer, the incidence of which more than doubled between 1975 and 1998, and is expected to double again by 2020. Chronic hepatitis C is associated with increased risk for other medical conditions outside the liver including diabetes, kidney disease, lymphoma, and neuropsychological maladies.At least 1 in 50 Americans has already been infected with the hepatitis C virus, and CDC's report indicates that at least 20,000 new infections occur annually. "With 4 to 5 million citizens already carrying the hepatitis C virus, and 50% to 75% of them being unaware that they've been infected, we clearly have an ongoing public health crisis on our hands," noted Hepatitis C Caring Ambassadors Program Director, Lorren Sandt.
