Transmission
You can get HCV from infected blood or body fluids. Today, the most common mode of transmission is needle-sharing during intravenous drug use, and most new infections now occur among intravenous drug users.
Since 1992, when reliable blood screening procedures became available, the risk of transmission of HCV via blood transfusion has fallen to less than one per million units of transfused blood, according to the Centers for Disease Control and Prevention (CDC).
Rarely, the virus can be transmitted through sexual intercourse. In addition, an infected pregnant woman can infect her unborn baby.
