Protect Yourself from Hepatitis B

The Basics

Hepatitis B is a virus that spreads from person to person through blood, semen (cum), and fluids from the vagina. A mother with hepatitis B can also pass it to her baby at birth.

Some people who get hepatitis B can get rid of the virus. Others develop chronic hepatitis B – a lifelong infection that can lead to liver disease and even death.

To protect yourself from hepatitis B:

    • Get the hepatitis B vaccine (shot) if you need it – and make sure your children get it.

 

    • Get tested for hepatitis B if you are at risk for infection.

 

    • Be safe when you travel to countries where hepatitis B is common.

Do I need the hepatitis B vaccine (shot)?

Hepatitis B can be prevented with a vaccine. The hepatitis B vaccine is recommended for:

    • All babies at birth

 

    • Anyone under age 19 who didn’t get the shots as a baby

 

    • Adults who are at risk for hepatitis B

 

If you think you might be at risk for hepatitis B, talk with your doctor or nurse about getting the vaccine. Find out more about who needs to get the hepatitis B vaccine.

Do I need to get tested for hepatitis B?

Other people need to get tested if they are at risk for hepatitis B. You are at risk if you:

    • Were born in a place where hepatitis B is common, like Asia or Africa

 

    • Have parents who were born in a place where hepatitis B is common

 

    • Are HIV-positive

 

    • Use drugs with needles

 

    • Live with someone who has hepatitis B

 

    • Have sex with someone who has hepatitis B

 

    • Are a man who has sex with men

 

    • Get kidney dialysis treatments

 

Can hepatitis B be treated?

Yes. The treatment for hepatitis B depends on the type of infection. The 2 types of hepatitis B infection are acute (short-term) or chronic(long-term).

Acute hepatitis B

When people first get infected with hepatitis B, it’s called acute hepatitis B. Many people with acute hepatitis B don’t have any symptoms and don’t need treatment. Or they have mild symptoms that might feel like the flu.

Some people with acute hepatitis B get very sick and need to go to the hospital, but that’s not common. For many people, acute hepatitis goes away by itself within 6 months.

Children under age 6 who get acute hepatitis B are at high risk for developing chronic hepatitis. That’s why the hepatitis B vaccine is recommended for all babies.

Chronic hepatitis B

Some people who get acute hepatitis B will develop a chronic hepatitis B infection. This means the infection will never go away. People with chronic hepatitis B may need to take medicine to help stop the virus from causing liver damage.

Take Action!

Take these steps to help protect yourself and your children from hepatitis B.

Get the hepatitis B vaccine (shot).

If you haven’t gotten the hepatitis B vaccine and you think you might be at risk for hepatitis B, talk with your doctor or nurse about getting the shot. Keep in mind that the vaccine won’t work if you’ve had hepatitis B in the past.
