Human Hepatitis C PB

Hepatitis C (HCV) primarily causes a long-lasting liver disease. It is spread by contact with infected blood. It first became evident in 1974 that a non A/non B hepatitis virus existed. Finally, a test was discovered that could be used to identify the virus in 1989 and from the early 1990s all blood units were screened for HCV. Hepatitis C is more likely than Hepatitis B to cause liver disease.
