How is hepatitis B passed on and who is at risk?


How does hepatitis B cause liver disease?


The hepatitis B virus is mostly passed on through blood. It can also be passed on in other body fluids such as semen (cum). This means that, if you live with hepatitis B, the virus can be passed on if your blood or other fluids mix with someone else’s.

Hepatitis B can be passed from a mother to her baby during birth. This is how most people with chronic hepatitis B got the virus.

The hepatitis B virus can live in dried blood for at least a week. So it is possible but unlikely for it to be passed on by sharing items that can get blood on them like razors.
