Transmission of hepatitis B results from exposure to infectious blood or body fluids containing blood. Possible forms of transmission include (but are not limited to) [[safe sex|unprotected sexual contact]], [[blood transfusion]]s, [[needle sharing|re-use of contaminated needles]] & syringes, and [[vertical transmission]] from mother to child during childbirth.
