Hepatitis B is a blood-borne pathogen; its primary mode of transmission is through direct blood-to-blood contact with an infected person. In contrast, hepatitis A can be spread by fecal-oral transmission or by consuming food or water that has been contaminated.

Hepatitis A virus (HAV), classified as hepatovirus, is a small, unenveloped symmetrical RNA virus which shares many of the characteristics of the picornavirus family, and is the cause of infectious or epidemic hepatitis transmitted by the fecal-oral route.

The most significant difference between hepatitis B and hepatitis C is that people may get hepatitis B from contact with the bodily fluids of a person who has the infection. Hepatitis C usually only spreads through blood-to-blood contact.
