Transmission routes of hepatitis C virus infection

چکیده
The definitive identification of the hepatitis C genome in 1989 resulted in confirmation that this virus is a worldwide health problem.(1) The hepatitis C virus (HCV) is one of the most common causes of chronic liver disease and is one of the principal indications for liver transplantation. It is estimated that about four million Americans harbor hepatitis C antibodies. The virus is present in the blood of three million Americans and is most prevalent in people between 40 and 60 years of age. Hepatitis A, B, and C viruses are members of the Flaviviridae. The virus consists of a single RNA chain surrounded by an envelope of host membrane into which glycoproteins have been inserted. Six genotypes of HCV have been identified philogenetically.
