The Hepatitis C virus is believed to be exclusively transmitted via the blood. The virus can transmit when the blood of an uninfected person gets in contact with the blood of an infected person.

 Hep C transmission is most likely to happen when the blood of an infected person comes in direct contact with the blood of an uninfected person such as in blood transfusions improperly screened, the shared use of needles among illicit drug users, accidental needle sticks with infected blood, and direct blood to blood contact with an infected person’s open wound.
