Internal Medicine | Hepatology Questions Hepatitis B

How is hepatitis B caused?

I was diagnosed with hepatitis B, and according to my doctor, I've had it a while. I'm not sure how I even had gotten it, especially since I haven't had unprotected sex recently (at least not that I recall). What are some other causes of hepatitis B?

It’s either through blood products such as blood transfusions or through sexual activity.
It’s transmitted by body fluids; saliva is less likely unless you kissed somebody and both of you had sores in your mouth. Also any blood-to-blood contact. Cheer up, though, because we now have very good treatment. I would recommend a liver specialist even if there is a long wait.

Hepatitis B can be spread through sexual contact, sharing injection needles, accidental needle sticks, blood transfusions, organ transplant or from mother to baby while giving birth.
