Hepatitis C (HCV) is most commonly transmitted through the:
- reuse or inadequate sterilization of medical equipment, especially syringes and needles in healthcare settings
- transfusion of unscreened blood and blood products
- injecting drug use through the sharing of injection equipment.
HCV can be passed from an infected mother to her baby and via sexual practices that lead to exposure to blood (for example, people with multiple sexual partners and among men who have sex with men); however, these modes of transmission are less common.
