How Do You Get Hep B From Using A Razor Blade Hepatitis B... How Is It Spread?

Hepatitis B... how is it spread? - how do you get hep b from using a razor blade

How is it spread? Can be transmitted through kissing? On the cheek? I know I read it before, but I do not know exactly. It is also possible for someone to hepatitis B without knowing that the knife had been used, but I noticed that the hair if you used that came with the hepatitis B? I know it looks like 5 years, but I can think of no better way to word the question .... If you HepB at birth, and baby kissing an infected person infected? After receiving all the vaccines protect against hepatitis and do not get?
