There is not one main cause it can happen in different ways like exchange of bodily fluids and certain infections. It is a liver disease and can be cured or at least suppressed
The main two causes of liver damage are alcoholism and hepatitis.
Usually caused by hepatitis B virus.
Hepatitis is caused by blood borne pathogens. The pathogens themselves conveniently share similar names to the type of hepatitis they cause: The pathogen that causes Hepatitus A is known as the Hepatitis A Virus (HAV), the pathogen that causes Hepatitus B is known as the Hepatitis B Virus (HBV) and the pathogen that causes Hepatitus C is known as the Hepatitis C Virus (HCV).

The hepatitis A virus (HAV) is the parasite that causes hepatitis A infection. It is primarily transmitted through ingestion of contaminated food or water.

Hepatitis is mainly caused by viruses, such as hepatitis A, B, and C. Bacterial infections can also lead to inflammation of the liver but are less common causes of hepatitis.
Intrahepatic cholestasis is usually caused by hepatitis or by medications that can produce symptoms resembling hepatitis
Cirrhosis is a degenerative illness affecting the liver and causing scarring. Alcohol misuse and hepatitis C are thought to be the two main causes of this illness.
Their main difference is their mode of transmission. Hepatitis A is fecal-oral while Hepatitis B is a blood-borne disease.
Hepatitis is actually quite a general term which means inflammation of the liver and so has many causes for example drug-induced, alcoholic, autoimmune or infectious. On the whole when most people refer to hepatitis they refer to infectious hepatitis often caused by the hepatitis viruses types B & C which have the potential to cause long term (chronic) hepatitis. There are other forms of the hepatitis virus family including types A, D & E and there are other forms of virus which can cause hepatitis. There are non-viral infectious causes of hepatitis including toxoplasma and Q fever (which is a bacteria) but these are rare.
