Risk Factors
One out of every 20 people in the United States will become infected with hepatitis B at some point during their life. People who are at increased risk for contracting hepatitis B include:
  • Asian-Pacific Americans: While 0.3% of the United States population has chronic hepatitis B, Asian-Pacific Americans make up more than half of the 1.3 to 1.5 million people with hepatitis B.
  • Infants and Children of Immigrants from Areas with High Rates of HBV Infection
  • Sexually Active Adults and Teenagers: this includes people who have had multiple sex partners (past or present); people who have been diagnosed with a sexually transmitted disease; and men who have sex with men.
  • Healthcare and Public Safety Workers
  • Injection Drug Users
  • People Who Get Tattoos or Body Piercings
  • Babies Born to Mothers Who Are HBV Carriers: 90 percent of babies who have hepatitis B at birth will be infected for the rest of their lives.
Other high-risk groups include partners of or people living in close household contact with an infected person, people who travel to countries where hepatitis B is common, and people who have hemophilia (a rare, inherited disorder in which the blood does not clot normally).

If you are in one of these high-risk groups or think you may have been in contact with a person infected with HBV, it is important that you visit your doctor or clinic. A simple blood test can easily determine whether or not you have been infected.
