Traditionally, viral hepatitis had been classified into two types: infectious(A) and serum(B).

hepA had a shoter incubation period, high contagious rate, and usually a fecal-oral route of transmission, hepB had a longer incubation period, was less contangious, and was thought to be transmitted only by the parenteral route.

 

Hepatitis A - this is caused by eating infected food or water. The food or water is infected with a virus called HAV (Hepatitis A Virus). Anal-oral contact during sex can also be a cause.
Hepatitis B - this is an STD (sexually transmitted disease). It is caused by the virus HBV (Hepatitis B Virus) and is spread by contact with infected blood, semen, and some other body fluids.

The liver of a person infected with Hepatitis B swells. The patient can suffer serious liver damage due to infection, resulting in cancer
