Transmission

The hepatitis B virus is transmitted through blood and bodily fluids. This can most commonly occur in the following ways:

blood icon  Direct contact with infected blood

Unprotected  Unprotected sex

injection drugs  Use of illegal or “street” drugs

biohazard  Needles that are contaminated or not sterile

mother to baby  From an infected woman to her newborn during pregnancy and childbirth

Body piercing, tattooing, acupuncture and even nail salons are other potential routes of infection unless sterile needles and equipment are used. In addition, sharing sharp instruments such as razors, toothbrushes, nail clippers, earrings and body jewelry can be a source of infection. 

Hepatitis B is NOT transmitted casually. It cannot be spread through toilet seats, doorknobs, sneezing, coughing, hugging or eating meals with someone who is infected with hepatitis B.


High-Risk Groups

The hepatitis B virus can infect infants, children, teens and adults. It is not a genetic disease – it is an infectious disease that is transmitted through blood. Although everyone may be at risk for a hepatitis B infection during their lifetime, there are groups of people who are at higher risk because of where they were born, their occupation or life choices.

The following is a guide for screening high-risk groups for hepatitis B, but the list certainly doesn't represent all potential risk factors.

  1. Health care providers and emergency responders
  2. Sexually active individuals (more than 1 partner in the past six months)
  3. Men who have sex with men
  4. Individuals diagnosed with a sexually transmitted disease
  5. Illicit drug users (injecting, inhaling, snorting, pill popping)
  6. Sexual partners or those living in close household contact with an infected person
  7. Individuals born in countries where hepatitis B is common (Asia, Africa, South America, Pacific Islands, Eastern Europe, and the Middle East)
  8. Individuals born to parents who have emigrated from countries where hepatitis B is common (see #7)
  9. Children adopted from countries where hepatitis B is common (see #7)
  10. Adoptive families of children from countries where hepatitis B is common (see #7)
  11. Kidney dialysis patients and those in early kidney (renal) failure
  12. Inmates and staff of a correctional facility
  13. Residents and staff of facilities for developmentally disabled persons
  14. ALL pregnant women
