Hep B lives in blood and sexual fluids. It does not travel through breast milk, saliva, skin, or air – so these are not transmission risks for hep B.

What are transmission risks for hep B?

  • From mother to baby at birth – this is the most common way hep B is transmitted.
  • By blood-to-blood contact (when the blood of a person with hep B enters another person’s body). This may happen when you share objects that have traces of blood on them, like toothbrushes, combs and razors, or injecting drug equipment or during unsterile cosmetic or medical procedures or tattoos.
  • From unprotected sex.
