Hepatitis means 'liver inflammation'. It is caused by a virus and around half of all acute cases of hepatitis are due to a viral infection. There are a total of seven hepatitis viruses, from A to G, but the most common are the hepatitis A and B viruses.
Hepatitis A, B and C will be covered in this section.
