Hepatitis C is a virus which infects the liver and can have serious health consequences including liver failure and liver cancer. The hepatitis C virus is spread from person to person through blood and body fluid contact. The Center for Disease Control (CDC) recommends a one-time screening blood test for all persons born between 1945 and 1965. If you have donated blood through the Red Cross since 1990, you have already been screened for Hepatitis C.
