Preventing hepatitis B or C

Hepatitis B and hepatitis C infections cause irritation (inflammation) and swelling of the liver. You should take steps to prevent catching or spreading these viruses since these infections can cause chronic liver disease.

Vaccines

All children should get the hepatitis B vaccine.

  • Babies should get a first dose of the hepatitis B vaccine at birth. They should have all three shots in the series by age 6 to 18 months.
  • Infants born to mothers who have acute hepatitis B or who are chronic hepatitis B carriers past should get hepatitis B immune globulin (HBIG) and the hepatitis B vaccine within 12 hours of birth.
  • Children younger than age 19 who have not had the vaccine should get "catch-up" doses.

Adults at high risk for hepatitis B should also be vaccinated, including:

  • Health care workers and those who live with someone who has hepatitis B
  • People with end-stage kidney disease, chronic liver disease, or HIV infection
  • People with multiple sex partners and men who have sex with other men
  • People who use recreational, injectable drugs

There is no vaccine for hepatitis C.

Lifestyle

Hepatitis B and C viruses are spread through contact with blood or bodily fluids of a person with the virus. The viruses are not spread through casual contact, such as holding hands, sharing eating utensils or drinking glasses, breastfeeding, kissing, hugging, coughing, or sneezing.

To avoid coming in contact with blood or bodily fluids of others:

  • Avoid sharing personal items, such as razors or toothbrushes
  • Do not share drug needles or other drug equipment (such as straws for snorting drugs)
  • Clean blood spills with a solution containing 1 part household bleach to 9 parts water
  • Be careful when getting tattoos and body piercings
  • Practice safer sex (especially for prevention of hepatitis B)

Safer sex means taking steps before and during sex that can prevent you from getting an infection, or from giving an infection to your partner.

Other steps you can take

Screening of all donated blood has reduced the chance of getting hepatitis B and C from a blood transfusion. People newly diagnosed with hepatitis B infection should be reported to state health care workers to track the population's exposure to the virus.

The hepatitis B vaccine, or an HBIG shot, may help prevent infection if it is received within 24 hours of contact with the virus.
