Hepatitis C Infection
Hepatitis C is caused by a RNA virus. The virus is spread through blood and blood products and the common ways of acquiring infection are intravenous drug use, needle stick exposure, tattoos, sexual promiscuity (multiple partners, gay population), sharing razors and toothbrushes etc. Blood transfusion was an important route of transmission before 1993 when serological testing was not available but now this is not a method of transmission. In about 20% of patients no risk factor can be identified.
