HEPATITIS C - A form of viral hepatitis, previously referred to as non a non b hepatitis, is the most common form of blood transfusion acquired hepatitis. Transmission through sexual contact is considered rare. Risk factors include recent blood transfusion, IV drug abuse, or occupational exposure to blood products. There is no specific treatment. There is a test for hepatitis c antibody which indicates prior exposure. Unlike hepatitis b there is no marker yet identifiable for those who suffer from chronic hepatitis c.
