Hepatitis C infection kills more people annually than HIV/AIDS. The reason is that HCV often does not have any symptoms until the disease progresses to the point where treatment can no longer help. The best way to prevent infection with HCV is to avoid contact with an infected person's blood, do not share needles, and avoid high-risk sexual behaviors (anal sex, multiple partners). If you do engage in high-risk behavior or think you may have been exposed to Hepatitis C, talk to your doctor and get tested.
