Protect Yourself from Hepatitis B

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 and your family from hepatitis B:

• Make sure your children get the hepatitis B vaccine (shot). And ask your doctor if you need it.
• Get tested for hepatitis B if you are pregnant or 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.

• 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

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. Some people have mild symptoms that might feel like the flu.

Only a few people with acute hepatitis B get very sick and need to go to the hospital. 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 these steps to help protect yourself and your children from hepatitis B.
