Answer

Hepatitis C virus (HCV) infection is the most common chronic bloodborne infection in the United States; it is also one of the leading known causes of liver disease in the United States. [4]

Approximately, 180 million people are infected worldwide with HCV, in the United States; the infection prevalence is estimated to be around 4 million people, with an estimated of 17000 new infections in 2010. Infection with HCV is a common cause of both acute and chronic liver disease; it is frequently a silent disease with few clinical manifestations; however, chronic hepatitis C is a common cause of cirrhosis, end-stage liver disease, and hepatocellular carcinoma. In the United States, it is the single major cause of chronic liver disease hence the principal reason for liver transplantation in adults. [5]

Hepatits C virus is a single-stranded positive-sense RNA virus; it is classified in the family of Flaviviridae on hepacivirus genus. Six major genotypes have been identified. [5]
