Hepatitis A, B and C
Hepatitis is the general term used to describe inflammation of the liver. The causes vary, and can include viruses, parasites or drug and alcohol use. Hepatitis is diagnosed after an analysis of the blood shows an elevation in liver enzymes (also referred to as ALT and AST). Hepatitis A is transmitted through oral-fecal contact. Hepatitis B is the most widespread form of the disease, and can be transmitted via blood transfusion, sharing needles or sexual intercourse. It is most commonly found in individuals who are also infected with HIV. Little is known about Hepatitis C, and the route of transmission is still unclear. In fact, it has only become possible to detect the presence of Hepatitis C in recent years.
