Hepatitis B Transmission

Hepatitis B transmission occurs when blood, semen, or another body fluid that is infected with the hepatitis B virus enters the body of an uninfected person. Among the common methods of HBV transmission are unsafe sexual practices and sharing contaminated needles. Transmission of the hepatitis B virus may also occur when an infected woman transfers the disease to her baby during childbirth.

 

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.
