An Overview of Hepatitis B Transmission
Transmission of the
hepatitis B virus (HBV) can occur in one of several ways. It can occur when blood from an infected person enters the body of a person who is not infected.
Hepatitis B transmission can also occur through contact with other body fluids, such as semen, vaginal fluids, or saliva.
Some specific ways in which the hepatitis B virus can be spread include:
- Through having sex with an infected person without using a condom (the effectiveness of latex condoms in preventing infection with HBV is unknown, but their proper use may reduce transmission)
- By sharing drugs, needles, or "works" when "shooting" drugs
- Through needlesticks or "sharps" exposures on the job
- Having a tattoo or body piercing done with dirty tools that were used on someone else
- By sharing objects that may have a very tiny amount of blood on them, such as a toothbrush, razor, or tools used for manicures
- From an infected mother to her baby during birth.
