Hepatitis B spreads through contact with blood, semen or other body fluids from an infected person. Your risk of hepatitis B infection increases if you:

  • Have unprotected sex with multiple sex partners or with someone who's infected with HBV
  • Share needles during intravenous (IV) drug use
  • Are a man who has sex with other men
  • Live with someone who has a chronic HBV infection
  • Are an infant born to an infected mother
  • Have a job that exposes you to human blood
  • Travel to regions with high infection rates of HBV, such as Africa, Central and Southeast Asia, and Eastern Europe
