Definition

Hepatitis C is a viral disease that leads to swelling (inflammation) of the liver.

Alternative Names

Non-A or non-B hepatitis

Causes, incidence, and risk factors

Hepatitis C infection is caused by the hepatitis C virus (HCV). People who may be at risk for hepatitis C are those who:

  • Have been on long-term kidney dialysis
  • Have regular contact with blood at work (for instance, as a health care worker)
  • Have unprotected sexual contact with a person who has hepatitis C (this is less common, but the risk increases for those who have multiple sex partners, already have a sexually transmitted disease, or are infected with HIV)
  • Inject street drugs or share a needle with someone who has hepatitis C
  • Received a blood transfusion before July 1992
  • Received a tattoo or acupuncture with contaminated instruments (the risk is very low with licensed, commercial tattoo facilities)
  • Received blood, blood products, or solid organs from a donor who has hepatitis C
  • Share personal items such as toothbrushes and razors with someone who has hepatitis C (less common)
  • Were born to a hepatitis C-infected mother (this is less common than with hepatitis B)

Hepatitis C has an acute and chronic form. Most people who are infected with the virus develop chronic hepatitis C.

Other hepatitis virus infections include hepatitis A and hepatitis B. Each viral hepatitis infection is caused by a different virus.
