Hepatitis B

Many people with hepatitis B may not show symptoms, but even if they feel healthy, they can still spread the virus to others. Getting tested and taking precautions are important for protecting both yourself and those around you. Below are key steps to help prevent hepatitis B infection: 

• Get vaccinated because it is the most effective way to prevent infection for babies, children, and adults. 

  • All newborns and children through age 18 should get the hepatitis B vaccine. 

  • Adults age 18 and older who are at increased risk should get the hepatitis B vaccine. If you are unsure where you are at risk, visit mass.gov for more information, or discuss it with your health care provider. 

• Get tested and treated because many people do not have symptoms or know they have it.

• Ensure pregnant people are screened to protect the newborn immediately after birth. 

  • If you have hepatitis B, be sure your health care provider knows so your baby gets a vaccine and hepatitis B immune globulin (HBIG). 

  • If you do not have hepatitis B, getting your baby vaccinated will help protect against future exposures and have long-lasting immunity into adulthood. 

•  Use barrier protection, like a condom, during sex to reduce the risk of transmission. 

• Avoid sharing needles, razors, toothbrushes, or anything that may have blood on it, particularly if you know you have hepatitis B.

In the event of exposure to the blood or body fluids of an infected person, wash the area with soap and water for at least 20 seconds and see a health care provider right away. 

Most people with acute hepatitis B recover on their own without medical treatment. There is currently no treatment that can prevent an acute infection from becoming chronic. 

Some individuals with chronic hepatitis B may benefit from ongoing medical care and antiviral treatment to reduce liver damage and lower the risk of complications. 

For people who are not infected, a safe and effective vaccine is available to prevent hepatitis B. If you have hepatitis B, it is important to: 

• See your health care provider regularly. 

• Avoid drinking alcohol. 

• Talk with your health care provider before taking any new medications, including dietary supplements, over the counter medicines, or herbal products. 

• Get vaccinated against hepatitis A and get tested for hepatitis C.
