The main cause of hepatitis is a virus, but there are other causes, too. The most common type of hepatitis is caused by a virus that attacks the liver. This virus is called hepatitis A, B, C, D, or E. Hepatitis can also be caused by drinking too much alcohol, taking certain drugs, being infected with parasites, or getting a bad reaction to certain medical treatments. In some cases, the cause of hepatitis is not known.
