What is the difference between hepatitis A, B and C?

Hepatitis A, hepatitis B and hepatitis C are all viruses that infect the liver. Each type of hepatitis is caused by a different virus. Although they can have similar symptoms during the acute (early infection) phase, the three viruses are transmitted in differently and infect the body and liver in different ways. 

One of the main differences between the diseases is that two of the three can be protected against with vaccination; there are vaccines to prevent hepatitis A and hepatitis B, however, there is no vaccine for hepatitis C.
