Hepatitis B

Hepatitis B is a viral infection that causes liver inflammation and damage. Inflammation is swelling that occurs when tissues of the body become injured or infected. Inflammation can damage organs. Viruses invade normal cells in your body. Many viruses cause infections that can spread from person to person. The hepatitis B virus spreads through contact with an infected person’s blood, semen, or other body fluids.

You can take steps to protect yourself from hepatitis B, including getting the hepatitis B vaccine. If you have hepatitis B, you can take steps to prevent spreading hepatitis B to others.

The hepatitis B virus can cause acute or chronic infection.

Acute Hepatitis B Virus

Some people have symptoms, which may last several weeks. In some cases, symptoms last up to 6 months. Sometimes the body can fight off the infection and the virus goes away. If the body isn’t able to fight off the virus, the virus does not go away, and chronic hepatitis B infection occurs. Most healthy adults and children older than 5 years who have hepatitis B get better and do not develop a chronic hepatitis B infection.

Chronic Hepatitis B Virus

Your chance of developing chronic hepatitis B is greater if you were infected with the virus as a young child. About 90 percent of infants infected with hepatitis B develop a chronic infection. About 25 to 50 percent of children infected between the ages of 1 and 5 years develop chronic infections. However, only about 5 percent of people first infected as adults develop chronic hepatitis B.

How common is hepatitis B?

Hepatitis B infection is more common in some other parts of the world than it is in the United States. Though less than 0.5 percent of the U.S. population has hepatitis B, 2 percent or more of the population is infected in areas such as Africa, Asia, and parts of the Middle East, Eastern Europe, and South America.

Hepatitis B infection has been especially common in some parts of the world, such as sub-Saharan Africa and parts of Asia, where 8 percent or more of the population was infected. In some of these areas, Hepatitis B infection rates are now lower than they were, but infection rates are still higher in these areas than in the United States.

Hepatitis B

Who is more likely to get hepatitis B Virus?

People are more likely to get hepatitis B if they are born to a mother who has hepatitis B. The virus can spread from mother to child during birth. For this reason, people are more likely to have hepatitis B if they

  • were born in a part of the world where 2 percent or more of the population has hepatitis B infection
  • were born in the United States, didn’t receive the hepatitis B vaccine as an infant, and have parents who were born in an area where 8 percent or more of the population had hepatitis B infection

People are also more likely to have hepatitis B if they

  • are infected with HIV, because hepatitis B and HIV spread in similar ways
  • have lived with or had sex with someone who has hepatitis B
  • have had more than one sex partner in the last 6 months or have a history of sexually transmitted disease
  • are men who have sex with men
  • are injection drug users
  • work in a profession, such as health care, in which they have contact with blood, needles, or body fluids at work
  • have diabetes
  • have hepatitis C
  • have been on kidney dialysis
  • live or work in a prison
  • had a blood transfusion or organ transplant before the mid-1980s

In the United States, hepatitis B spreads among adults mainly through contact with infected blood through the skin, such as during injection drug use, and through sexual contact.

Should I be screened for hepatitis B Virus?

Screening is testing for a disease in people who have no symptoms. Doctors use blood tests to screen for hepatitis B. Many people who have hepatitis B don’t have symptoms and don’t know they are infected with hepatitis B. Screening tests can help doctors diagnose and treat hepatitis B, which can lower your chances of developing serious health problems.

  • are pregnant
  • were born in an area of the world where 2 percent or more of the population has hepatitis B infection, which includes Africa, Asia, and parts of the Middle East, Eastern Europe, and South America
  • didn’t receive the hepatitis B vaccine as an infant and have parents who were born in an area where 8 percent or more of the population had hepatitis B infection, which includes sub-Saharan Africa and parts of Asia
  • are HIV-positive
  • have injected drugs
  • are a man who has sex with men
  • have lived with or had sex with a person who has hepatitis B
  • have an increased chance of infection due to other factors

What are the complications of the hepatitis B Virus?

Hepatitis B may lead to serious complications. Early diagnosis and treatment can lower your chances of getting complications.

Acute hepatitis B complications

In rare cases, acute hepatitis B can lead to acute liver failure, a condition in which the liver fails suddenly. People with acute liver failure may require a liver transplant.

Chronic hepatitis B complications

Chronic hepatitis B can lead to

  • cirrhosis, a condition in which scar tissue replaces healthy liver tissue and prevents your liver from working normally. Scar tissue also partially blocks the flow of blood through the liver. As cirrhosis gets worse, the liver begins to fail.
  • liver failure, in which your liver is badly damaged and stops working. Liver failure is also called end-stage liver disease. People with liver failure may require a liver transplant.
  • liver cancer. Your doctor may suggest blood tests ultrasound or another type of imaging test to check for liver cancer. Finding cancer at an early stage improves the chance of curing cancer.

Reactivated hepatitis B Virus

In people who have ever had hepatitis B, the virus may become active again, or reactivated, later in life. When hepatitis B is reactivated, it may start to damage the liver and cause symptoms. Reactivated hepatitis B can lead to acute liver failure.

Hepatitis B

What are the symptoms of hepatitis B Virus?

Many people infected with hepatitis B have no symptoms.

Some people with acute hepatitis B have symptoms 2 to 5 months after they come in contact with the virus.6 These symptoms may include

  • dark yellow urine
  • feeling tired
  • fever
  • gray- or clay-colored stools
  • joint pain
  • loss of appetite
  • pain in the abdomen
  • vomiting
  • yellowish eyes and skin, called jaundice

Infants and children younger than age 5 typically don’t have symptoms of acute hepatitis B. Older children and adults are more likely to have symptoms.

If you have chronic hepatitis B, you may not have symptoms until complications develop, which could be decades after you were infected. For this reason, hepatitis B screening is important, even if you have no symptoms.

What causes the hepatitis B Virus?

The hepatitis B virus causes hepatitis B. The hepatitis B virus spreads through contact with an infected person’s blood, semen, or other body fluids. Contact can occur by

  • being born to a mother with hepatitis B
  • having unprotected sex with an infected person
  • sharing drug needles or other drug materials with an infected person
  • getting an accidental stick with a needle that was used on an infected person
  • being tattooed or pierced with tools that were used on an infected person and weren’t properly sterilized, or cleaned in a way that destroys all viruses and other microbes
  • having contact with the blood or open sores of an infected person
  • using an infected person’s razor, toothbrush, or nail clippers

You can’t get hepatitis B from

  • being coughed on or sneezed on by an infected person
  • drinking unclean water or untreated water that has not been boiled
  • eating food that is unclean or has not been properly cooked
  • hugging an infected person
  • shaking hands or holding hands with an infected person
  • sharing spoons, forks, and other eating utensils
  • sitting next to an infected person

Mothers who have hepatitis B can safely breastfeed their babies. If a baby receives hepatitis B immune globulin (HBIG) and starts receiving the hepatitis B vaccine to prevent hepatitis B infection shortly after birth, hepatitis B is unlikely to spread from mother to child through breastfeeding.15

How do doctors diagnose hepatitis B Virus?

Doctors diagnose hepatitis B based on your medical and family history, a physical exam, and blood tests. If you have hepatitis B, your doctor may perform additional tests to check your liver.

Physical exam

During a physical exam, your doctor will check for signs of liver damage such as

  • changes in skin color
  • swelling in your lower legs, feet, or ankles
  • tenderness or swelling in your abdomen

What tests do doctors use to diagnose hepatitis B Virus?

Doctors use blood tests to diagnose hepatitis B. Your doctor may order additional tests to check for liver damage, find out how much liver damage you have, or rule out other causes of liver disease.

Blood tests

Your doctor may order one or more blood tests to diagnose hepatitis B. A healthcare professional will take a blood sample from you and send the sample to a lab.

Certain blood tests can show whether you are infected with hepatitis B. If you are infected, your doctor may use other blood tests to find out

  • whether the infection is acute or chronic
  • whether you have an increased chance of liver damage
  • whether the virus levels in your body are high or low
  • whether you need treatment

If you have chronic hepatitis B, your doctor will recommend testing your blood regularly because chronic hepatitis B can change over time. Even if the infection is not damaging your liver when you are first diagnosed, it may damage your liver in the future. Your doctor will use regular blood tests to check for signs of liver damage, find out if you need treatment, or see how you are responding to treatment.

Blood tests can also show whether you are immune to hepatitis B, meaning you can’t get hepatitis B. You may be immune if you got a vaccine or if you had an acute hepatitis B infection in the past and your body fought off the infection.

Additional tests

If you’ve had chronic hepatitis B for a long time, you could have liver damage. Your doctor may recommend additional tests to find out whether you have liver damage, how much liver damage you have, or to rule out other causes of liver disease. These tests may include

  • blood tests
  • transient elastography, a special ultrasound of your liver
  • liver biopsy, in which a doctor uses a needle to take a small piece of tissue from your liver

Doctors typically use liver biopsy only if other tests don’t provide enough information about a person’s liver damage or disease. Talk with your doctor about which tests are best for you.

How do doctors treat hepatitis B?

Doctors typically don’t treat hepatitis B unless it becomes chronic. Doctors may treat chronic hepatitis B with antiviral medicines that attack the virus.

Not everyone with chronic hepatitis B needs treatment. If blood tests show that hepatitis B could be damaging a person’s liver, a doctor may prescribe antiviral medicines to lower the chances of liver damage and complications.

Medicines that you take by mouth include

How do doctors treat the complications of hepatitis B?

If chronic hepatitis B leads to cirrhosis, you should see a doctor who specializes in liver diseases. Doctors can treat the health problems related to cirrhosis with medicines, minor medical procedures, and surgery. If you have cirrhosis, you have an increased chance of liver cancer. Your doctor may order blood tests ultrasound or another type of imaging test to check for liver cancer.

If chronic hepatitis B leads to liver failure or liver cancer, you may need a liver transplant.

How can I protect myself from hepatitis B infection?

You can protect yourself from hepatitis B by getting the hepatitis B vaccine. If you have not had the vaccine, you can take steps to reduce your chance of infection.

Hepatitis B vaccine

The hepatitis B vaccine has been available since the 1980s and should be given to newborns, children, and teens in the United States. Adults who are more likely to be infected with hepatitis B or who have chronic liver disease should also get the vaccine. The hepatitis B vaccine is safe for pregnant women.

Hepatitis B

Doctors most often give the hepatitis B vaccine in three shots over 6 months. You must get all three shots to be fully protected. In some cases, doctors may recommend a different number or timing of vaccine shots.

Reduce your chance of infection

You can reduce your chance of hepatitis B infection by

  • not sharing drug needles or other drug materials
  • wearing gloves if you have to touch another person’s blood or open sores
  • Make sure your tattoo artist or body piercer uses sterile tools
  • not sharing personal items, such as toothbrushes, razors, or nail clippers
  • using a latex or polyurethane condom during sex

Prevent infection after contact with the virus

If you think you have been in contact with the hepatitis B virus, see your doctor right away. Doctors typically recommend a dose of the hepatitis B vaccine to prevent infection. In some cases, doctors may also recommend a medicine called hepatitis B immune globulin (HBIG) to help prevent infection. You must get the vaccine dose and, if needed, HBIG shortly after coming into contact with the virus, preferably within 24 hours.

How can I prevent spreading hepatitis B to others?

If you have hepatitis B, follow the steps above to avoid spreading the infection. Your sex partners should get a hepatitis B test and, if they aren’t infected, get the hepatitis B vaccine. You can protect others from getting infected by telling your doctor, dentist, and other health care professionals that you have hepatitis B. Don’t donate blood or blood products, semen, organs, or tissue.

Prevent hepatitis B infections in newborns

If you are pregnant and have hepatitis B, talk with your doctor about lowering the risk that the infection will spread to your baby. Your doctor will check your virus levels during pregnancy. If virus levels are high, your doctor may recommend treatment during pregnancy to lower virus levels and reduce the chance that hepatitis B will spread to your baby. Your doctor may refer you to a liver specialist to find out if you need hepatitis B treatment and to check for liver damage.

When it is time to give birth, tell the doctor and staff who deliver your baby that you have hepatitis B. A healthcare professional should give your baby the hepatitis B vaccine and HBIG right after birth. The vaccine and HBIG will greatly reduce the chance of your baby getting the infection.

Clinical Trials for Hepatitis B

The NIDDK conducts and supports clinical trials in many diseases and conditions, including liver diseases. The trials look to find new ways to prevent, detect, or treat disease and improve quality of life.

What are clinical trials for hepatitis B?

Clinical trials—and other types of clinical studies are part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about the disease and improve health care for people in the future.

Researchers are studying many aspects of hepatitis B, such as

  • progression of hepatitis B and long-term outcomes
  • new treatments for hepatitis B
  • prevention of reactivated or worsening hepatitis B in people receiving cancer treatment
