Hepatitis C is a disease of the liver caused by the hepatitis C virus (HCV). The presence of HCV RNA (ribonucleic acid) in serum indicates infection. There are 2 main phases of infection: acute and chronic. Acute hepatitis C refers to the period immediately after infection, whereas chronic hepatitis C is defined as infection that lasts for more than 6 months. In the UK, there are 2 major routes of HCV transmission: sharing needles in intravenous drug misuse and receiving transfusions of infected blood or blood products. However, children acquire the virus primarily from their mothers at birth. Breast feeding does not appear to increase the risk of HCV transmission.
