Preparing For An Appointment
You’re likely to start by seeing your family health care provider. However, in some cases, you may be referred immediately to a specialist. Doctors who specialize in treating hepatitis B include:
- Doctors who treat digestive diseases
- Doctors who treat liver diseases
- Doctors who treat infectious diseases
How Common Is Hepatitis B
The number of people who get this disease is down, the CDC says. Rates have dropped from an average of 200,000 per year in the 1980s to around 20,000 in 2016. People between the ages of 20 and 49 are most likely to get it.
About 90% of infants and 25-50% of children between the ages of 1-5 will become chronically infected. In adults, approximately 95% will recover completely and will not go on to have a chronic infection.
As many as 1.2 million people in the U.S. are carriers of the virus.
Unlocking The Immune System To Control Hepatitis B
One sequence of the viral RNA code can contribute to several different hepatitis B virus proteins and also to viral replication. By targeting that sequence for clean out there is a potential broad impact on viral protein production, with the goal of eliminating the proteins effects on the immune system. This could set the stage for the immune system to take over and keep the virus suppressed for the long term without the need for ongoing medication.
Whilst the ultimate aspiration is to find a cure for hepatitis B, this approach could lead to what is called a functional cure, where the virus is undetectable in blood and at a low enough level in the liver that it can be controlled by the immune system without medication, meaning liver damage is less likely to progress and the burden of the disease on people will be reduced. Scientists hope this new approach will control the hepatitis B virus and lead to longer-lasting solutions for the 296 million people currently living with this disease.
Hepatitis B has been causing death and disability on a global scale for many years. We are committed to following the science to explore new approaches to address unmet needs and provide longer-lasting solutions for patients with this potentially life-threatening liver infection.

What Do I Need To Know About Having Hepatitis B
If you have chronic hepatitis B, getting the right medical care can help you stay healthy. Taking good care of your liver is important. Talk with your doctor before you take any prescription medication, over-the-counter drugs, vitamins, or nutritional supplements to make sure they wont hurt your liver. You should also stay away from alcohol, because drinking can damage your liver.
What Laboratory Tests Are Available For Hepatitis B
Tests are available to detect the types of antigens used to identify the hepatitis B virus. The tests determine if the virus is present in the body tissue or blood. The amount of each type of antigen present indicates how advanced the disease is and how infective the individual has become.
Other tests are available to detect the body’s reaction to the viral infection or the body’s reaction to vaccination against the virus. These tests work by measuring the number of antibodies present in the blood.

How Do People Get The Hbv Virus
Hepatitis B virus is found in the blood of people with HBV infection. It enters the body through blood-to-blood contact.
Reliable blood tests for HBV were developed many years ago. Since blood donors and blood products are tested for HBV, this is no longer the typical means of infection.
In many parts of the world, hepatitis B virus infects more than 8% of the population. HBV-infected women pass the infection to their babies during the birth process. People can also get hepatitis B by sharing needles for injection drug use, through sexual contact with an infected person, by an accidental needlestick with a contaminated needle, or from improperly sterilized medical, acupuncture, piercing, or tattooing equipment.
What Are The Symptoms Of Chronic Hepatitis B
About 1 in 20 people who get hepatitis B as adults become carriers, which means they have a chronic hepatitis B infection. Carriers are more likely to pass hepatitis B to other people. Most carriers are contagious meaning they can spread hepatitis B for the rest of their lives.
Hepatitis B infections that last a long time may lead to serious liver diseases like cirrhosis and liver cancer. About 1 in 5 people with chronic hepatitis B die from it. There are medicines that can help treat chronic hepatitis B infections.
Most babies who get hepatitis B develop chronic infection, unless they get treated right away. But treatments almost always work if your baby gets them quickly. Thats why its important for pregnant people to get tested for hepatitis B.

Hepatitis B Treatment Is There A Cure
Normally acute Hepatitis B does not require special treatment and the majority of adults clear the virus spontaneously. Early treatment may be required only in less than 1% of infected people who are immunocompromised or whose infection takes an aggressive course.
Its very important to maintain comfort, avoid alcohol, keep to a balanced diet, and replace body fluids lost from diarrhea and vomiting. On the other hand, chronic hepatitis B can be treated with medicines, including antiviral agents. Treatment can help to reduce the risk of cirrhosis and liver cancer.
Chronic Hepatitis B is usually a mild disease among children. Most of them can live full and healthy lives without visible symptoms. However, in some children the virus can cause significant liver damage. They will require medical treatment and intervention. All children suffering from chronic hepatitis B infection should be seen by a liver specialist on a regular basis. During the visits its necessary to take blood tests, physical exams and sometimes ultrasounds of the liver.
Whats The Difference Between Acute And Chronic Hepatitis B
Hepatitis B can be either acute or chronic:
- Acute hepatitis B lasts for a short period of time. If you have acute hepatitis B, you may be asymptomatic or have symptoms and develop icteric hepatitis. It can transition into chronic hepatitis B if the virus doesnt naturally go away after 6 months.
- Chronic hepatitis B lasts for at least 6 months. If you have this type of hepatitis, you may carry the hepatitis B virus for the rest of your life. Its possible to have chronic hepatitis B that started as acute, but many people dont have acute hepatitis B first.
Most people with acute hepatitis B make a full recovery. Some may never even show any symptoms. But those with chronic hepatitis B often need treatment to help manage the infection. Chronic hepatitis B also increases your risk of developing cirrhosis and certain types of liver cancer.
Your risk of developing chronic hepatitis B depends on when you first received your diagnosis of the virus. Children who receive a diagnosis of hepatitis B, especially those under the age of 5 years old, have a higher risk of the infection becoming chronic. Adults are less likely to develop chronic hepatitis B. Around 90 percent of adults who develop it will fully recover.
Keep in mind that hepatitis B can be present for years before you start to show any symptoms.

Is There A Cure
Though there is no vaccine for Hepatitis C, treatments can reduce the viral load to undetectable levels which is considered cured or in remission.
The virus is considered cured when it is not detected in your blood 12 weeks after treatment is completed. This is otherwise known as a sustained virologic response .
Hepatitis C is one of the most serious hepatitis viruses. However, with newer treatments developed over the past few years, the virus is much more manageable than it was in the past.
Current antiviral drugs that help cure hepatitis C may also help prevent the health complications of chronic liver disease.
The reports less than half of people who contract the hepatitis C virus may clear it from their bodies without treatment. For this group of people, the virus will be a short-term acute condition that goes away without treatment.
But for most people, acute hepatitis C will likely develop into a chronic condition that requires treatment.
Since the virus often doesnt produce symptoms until after more significant liver damage occurs, its important to get tested for hepatitis C if you think you might have been exposed.
approved the antiviral drug Mavyret for an 8-week treatment period for people with all genotypes of hepatitis C.
This treatment is now being used for many people instead of the 12-week treatment that was previously required.
Noninvasive ways to test for liver damage caused by hepatitis C are also now available to aid in diagnosis.
Is There A Cure For Chronic Hepatitis B
Currently, there is no complete cure for hepatitis B. But when managed properly, those living with the virus can expect to live a normal life. Maintaining a healthy diet and avoiding beverages that contain alochol and tobacco products are crucial components in managing the disease.
You should also visit a doctor familiar with hepatitis B at least annually though twice a year might be best to monitor your liver through blood tests and medical imaging. As with most diseases, detecting it early leads to a better outcome. If youre exposed to the virus, you should get an antibody injection within 12 hours of exposure.

Chronic Hepatitis B Symptoms
Most patients with chronic hepatitis B are asymptomatic unless their disease progresses. Others might have nonspecific symptoms, such as fatigue.
Some patients experience worsening of the infection and develop signs and symptoms similar to acute hepatitis.
If patients with chronic hepatitis B progress to cirrhosis they will develop signs and symptoms of liver failure, including:
- Peripheral edema

What Are The Types Of Hepatitis B
There are two types of hepatitis B infection: acute and chronic.
Acute
An acute infection happens at the beginning, when you first get infected with hepatitis B. Many people are able to clear it from their bodies and recover. In fact, this is true of about 4 in 5 adults who are infected.
Chronic
If you are not able to clear the infection within six months or longer, you have chronic hepatitis B. It is chronic hepatitis B that leads to inflammation and the serious, and possibly fatal, illnesses of cirrhosis of the liver and liver cancer. Treatment can slow disease progress, reduce the chance of liver cancer and increase your chances of surviving.

Testing & Vaccination
- The hepatitis B vaccine offers excellent protection against HBV. The vaccine is safe and highly effective. Vaccination consists of 3 doses of vaccine over the course of 6 months. Protection lasts for 20 years to life.
- The American Academy of Pediatrics recommends that all children should receive hepatitis B vaccine starting at birth. .
- The CDC recommends hepatitis B vaccine for persons traveling to countries where HBV is common .
- If you have one or more risk factors for hepatitis B infection, you should get a simple HBV blood test. The blood test will determine whether you are:
- immune to hepatitis B or
- susceptible to hepatitis B and need vaccination or
- infected with hepatitis B and need further evaluation by a physician
Perinatal Hepatitis
- California law requires testing of all pregnant women for hepatitis B infection
- If the mother is HBV-infected, she will pass the infection to the baby during the birth process, unless the baby gets immunized within hours of birth
- Giving the infant HBIG and HBV vaccine right away will reliably prevent infection of the infant
- Other family members should best tested for hepatitis B too, and given vaccine if they are not already infected or immune

What Occupations Have Increased Risk Of Hepatitis B
In general, occupational groups with increased risk include:
- Health-care workers repeatedly exposed to blood or blood products or those who are at risk of needlestick injury.
- Pathologists, laboratory personnel, or embalmers.
- Dentists, dental assistants, and dental hygienists.
- Certain staff members of institutions for the developmentally handicapped.
- Staff of institutions where workers may be exposed to aggressive, biting residents.
Travellers to regions with intermediate or high rates of endemic HBV infection may also consider being vaccinated.

How Is Hepatitis B Transmitted
Hepatitis B is spread in several distinct ways: sexual contact sharing needles, syringes, or other drug-injection equipment or from mother-to-child at birth.
In the United States, in 2018, injection drug use was the most common risk factor reported among people with an acute HBV infection, followed by having multiple sex partners. Less commonly reported risk factors included accidental needle sticks, surgery, transfusions, and household contact with a person with HBV infection. In the United States, healthcare-related transmission of HBV is rare.
Mother-to-child transmission of HBV is especially concerning, because it is preventable. An estimated 25,000 infants are born to mothers diagnosed with HBV each year in the United States, and approximately 1,000 mothers transmit HBV to their infants. Without appropriate medical care and vaccinations, 90% of HBV-infected newborns will develop chronic infection, remaining infected throughout their lives. Up to 25% of people infected at birth will die prematurely of HBV-related causes. For this reason, the standard of care for pregnant women includes an HBV test during each pregnancy so that the appropriate steps can be taken to prevent HBV-positive mothers from transmitting the disease to her infant.
What Are The Risk Factors For Getting Hepatitis B
Due to the way that hepatitis B spreads, people most at risk for getting infected include:
- Children whose mothers have been infected with hepatitis B.
- Children who have been adopted from countries with high rates of hepatitis B infection.
- People who have unprotected sex and/or have been diagnosed with a sexually transmitted infection.
- People who live with or work in an institutional setting, such as prisons or group homes.
- Healthcare providers and first responders.
- People who share needles or syringes.
- People who live in close quarters with a person with chronic hepatitis B infection.
- People who are on dialysis.

Who Is Most Affected
In the United States, rates of new HBV infections are highest among adults aged 30-59 years, reflecting low hepatitis B vaccination coverage among adults at risk. The most common risk factor among people with new HBV infections is injecting drugs, related to the opioid crisis and other drug use.
The highest rates of chronic hepatitis B infection in the United States occur among foreign-born individuals, especially people born in Asia, the Pacific Islands, and Africa. Approximately 70% of cases in the United States are among people who were born outside of the United States. CDC developed this map of the geographic distribution of hepatitis B around the world – PDF. Other groups who have higher rates of chronic HBV infection include people who inject drugs and men who have sex with men.
Where Can I Get A Hepatitis B Test
You can get tested for hepatitis B and other STDs at your doctors office, community health clinic, the health department, or your local Planned Parenthood health center.
Getting tested for STDs can sometimes feel scary, but once you get it over with it can really put your mind at ease. And if you DO have an STD, its best to know sooner so you can get the care you need.
STD testing isnt usually part of your regular checkup or gynecologist exam you have to ask for it directly. Be open and honest with your nurse or doctor so they can help figure out what tests are best for you. Dont be embarrassed: doctors are there to help, not judge.
Its extra important to get tested if youre pregnant or trying to get pregnant. Hepatitis B can easily spread to your baby during birth, which can be dangerous. If you have hepatitis B, your doctor can give your baby treatments.

Can Hepatitis Be Prevented
There are different ways to prevent or lower your risk for hepatitis, depending on the type of hepatitis. For example, not drinking too much alcohol can prevent alcoholic hepatitis. There are vaccines to prevent hepatitis A and B. Autoimmune hepatitis cannot be prevented.
NIH: National Institute of Diabetes and Digestive and Kidney Diseases
The Hepatitis B Vaccine
Getting the hepatitis B vaccine is one of the most effective ways to prevent hepatitis B. Its usually administered in two, three, or four doses. In many countries, infants receive their first dose of the vaccine at birth.
The Centers for Disease Control and Prevention recommends that infants receive their first dose of the vaccine at birth and finish all doses at 6 to 18 months old.
The CDC also recommends all children under the age of 19 years old be vaccinated if they havent already received the vaccination.
Adults can also get the hepatitis B vaccine. The vaccine is generally recommended if you have an increased risk of contracting the virus. Some of these risk factors include:
- traveling to or living in a region where hepatitis B is common
- being sexually active with more than one partner or with a partner who has hepatitis B
- working in a medical setting or other workplaces where youre exposed to bodily fluids
- using intravenous drugs and sharing drug equipment
- having chronic liver disease, a human immunodeficiency virus infection, a hepatitis C infection, diabetes, or kidney disease on dialysis
If youve been exposed to the hepatitis B virus and havent been vaccinated, try to see a doctor right away. They can administer the first dose of the vaccine, though youll need to follow up to receive the remaining doses over the next few months.
