Hepatitis C infection (Medical animation)

1 decade 5 years 7 months 4 weeks ago

Hepatitis C is an infectious disease affecting the liver, caused by the hepatitis C virus (HCV). The infection is often asymptomatic, but once established, chronic infection can progress to scarring of the liver (fibrosis), and advanced scarring (cirrhosis). In some cases, those with cirrhosis will go on to develop liver failure or other complications of cirrhosis, including liver cancer.

The hepatitis C virus (HCV) is spread by blood-to-blood contact. Most people have few symptoms after the initial infection, yet the virus persists in the liver in about 80% of those infected. Persistent infection can be treated with medication, such as interferon and ribavirin, but only a minority is cured. Those who develop cirrhosis or liver cancer may require a liver transplant, although the virus may recur after transplantation.

An estimated 150-200 million people worldwide are infected with hepatitis C. Apart from humans, it only infects chimpanzees. No vaccine against hepatitis C is available. The existence of hepatitis C (originally "non-A non-B hepatitis") was postulated in the 1970s and proved conclusively in 1988. It is one of five known hepatitis viruses: A, B, C, D, and E.
