Is Your Child at Risk for Hepatitis B? 

The preteen years are a time when young people try out new things. They start to become more independent. For these reasons, it is very important that you make sure your child has been vaccinated against hepatitis B (hep B). The hep B virus can be spread by having sex with an infected person without using a condom and by sharing infected needles. Even sharing a toothbrush or a razor can spread hep B.  

What is hepatitis B?

Hepatitis B is a highly contagious, sexually transmitted infection. It is caused by a virus that attacks the liver. It can possibly cause lifelong liver infection, scarring of the liver, liver cancer, and death. In the U.S., hep B causes an estimated 2,000 to 4,000 deaths each year.

People of any age can become infected with hep B. Coming in contact with a small amount of blood or body fluids from an infected person can infect a person who is not protected against hep B.

The good news is that hep B can be prevented through vaccines.

These factors put a person at high risk for getting hep B:

  • Having unprotected sex

  • Having sex with more than one partner

  • Having another sexually transmitted infection

  • Using injected drugs or sharing drug paraphernalia such as straws

  • Using unsterilized needles when tattooing, ear-piercing, or body-piercing

  • Sharing personal items like razors or toothbrushes with an infected person

  • Sharing chewing gum with an infected person

  • Touching fresh skin breaks, cuts, burns, or blood of an infected person

  • Living with a long-term infected person

  • Working in a hospital or other healthcare facility where it is possible to come in contact with fresh skin breaks, cuts, burns, blood, or blood-contaminated body fluids

Pregnant women with hep B can infect their children during childbirth. Infected people can pass the virus to their babies if they pre-chew food for them.

What are the symptoms of hepatitis B?

Teens who get hep B often have no signs. In some cases, they may have these symptoms:

  • Fever

  • Loss of appetite

  • Nausea or vomiting

  • Weakness or tiredness

  • Stomach pain

  • Light-colored bowel movements

  • Dark urine

  • Yellow coloring to the skin and eyes

  • Easy bruising

In the U.S., babies have been vaccinated against hep B since 1991. Health experts recommend the hep B vaccine for all babies and children who have not yet been vaccinated. They also recommend it for adults who are at high risk.

Talk with your child's healthcare provider about the hep B vaccine.
