How Does One Get Hepatitis B

What Are The Symptoms Of Chronic Hepatitis B

What is Hepatitis B? | How is Hepatitis B Transmitted?

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 Surface Antigen Test

A hepatitis B surface antigen test shows if youre contagious. A positive result means you have hepatitis B and can spread the virus. A negative result means you dont currently have hepatitis B. This test doesnt distinguish between chronic and acute infection. This test is used together with other hepatitis B tests to determine the .

How Do You Get Hepatitis C

Just like hepatitis B, you can get this type by sharing needles or having contact with infected blood. You can also catch it by having sex with somebody who’s infected, but that’s less common.

If you had a blood transfusion before new screening rules were put in place in 1992, you are at risk for hepatitis C. If not, the blood used in transfusions today is safe. It gets checked beforehand to make sure it’s free of the virus that causes hepatitis B and C.

It’s rare, but if you’re pregnant and have the disease, it’s possible to pass it to your newborn.

There are some myths out there about how you get hepatitis C, so let’s set the record straight. It’s not spread by food and water . And you canât spread it by doing any of these things:

  • Joint pain

See your doctor as soon as possible if you have any of these symptoms.

Sometimes, people have no symptoms. To be sure you have hepatitis, youâll need to get tested.

Who’s Most At Risk Of Hepatitis B

People at highest risk of hepatitis B include:

  • people born or brought up in a country where the infection is common
  • babies born to mothers infected with hepatitis B
  • people who have ever injected drugs
  • anyone who has had unprotected sex, including anal or oral sex particularly people who have had multiple sexual partners, people who have had sex with someone in or from a high-risk area, men who have sex with men, and commercial sex workers
  • close contacts, such as family members, of someone with a long-term hepatitis B infection

The risk of getting hepatitis B for travellers going to places where the infection is common is generally considered to be low if these activities are avoided.

Your GP can arrange for you to have a blood test to check for hepatitis B and have the hepatitis B vaccination if you’re at a high risk.

What Is Involved In A Liver Transplant

Why do newborns need the hepatitis B vaccine?

A liver transplant is considered necessary when the liver is damaged and cannot function or in some cases of liver cancer. Your liver is very important. It is responsible for many functions related to making sure that your body stays healthy and is able to digest foods.

You may be eligible for a transplant if you have chronic hepatitis B infection or some of the diseases that may result from it, including liver cancer and cirrhosis. You will have to complete testing and be evaluated before being approved for a transplant. It is likely that you will be placed on a waiting list while an appropriate organ is found.

Donated livers come from two types of donors: living and deceased. Because the liver can regenerate, it is possible to use part of a liver for transplant. The remaining sections in both the donor and the receiver will grow into livers of adequate size.

People who get liver transplants must take anti-rejection drugs for the rest of their lives. These drugs make you more susceptible to infection. However, liver transplants have become more successful over time and continue to improve.

Hepatitis B Vs Hepatitis C

Hepatitis has many different types. HBV and the hepatitis C virus have both acute and chronic forms.

The main difference between HBV and HCV is how they spread from person to person. Although HCV is transmissible via sexual activity, this is rare. HCV usually spreads when blood that carries the virus comes into contact with blood that does not.

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.

Hepatitis B During Pregnancy

Hepatitis B: Treatment and care for a chronic condition

If a woman with HBV becomes pregnant, they may transmit the virus to their baby. Women should inform the doctor who delivers their baby that they have HBV.

The infant should receive an HBV vaccine and HBIG with 1224 hours of birth. This significantly reduces the risk that they will develop HBV.

The HBV vaccine is safe to receive while pregnant.

People with a high risk of HBV include:

  • the infants of mothers with HBV
  • the sexual partners of people with HBV
  • people who engage in sexual intercourse without contraception and those who have multiple sexual partners
  • men who have sex with men
  • people who inject illicit drugs
  • those who share a household with a person who has a chronic HBV infection
  • healthcare and public safety workers who are at risk of occupational exposure to blood or contaminated bodily fluids
  • people receiving hemodialysis, which is a type of kidney treatment
  • people taking medications that suppress the immune system, such as chemotherapy for cancer
  • those who come from a region with a high incidence of HBV
  • all women during pregnancy

People can prevent HBV infection by:

  • wearing appropriate protective equipment when working in healthcare settings or dealing with medical emergencies
  • not sharing needles
  • following safe sexual practices
  • cleaning any blood spills or dried blood with gloved hands using a 1:10 dilution of one part household bleach to 10 parts water

A vaccine against HBV has been available since 1982.

People who should receive this vaccine include:

About The Hepatitis B Virus

The hepatitis B virus is a small DNA virus that belongs to the Hepadnaviridae family. Related viruses in this family are also found in woodchucks, ground squirrels, tree squirrels, Peking ducks, and herons.

Structure of the Hepatitis B Virus The hepatitis B virus contains an outer envelope and an inner core.

  • The outer envelope of the virus is composed of a surface protein called the hepatitis B surface antigen or “HBsAg”. The HBsAg can be detected by a simple blood test and a positive test result indicates a person is infected with the hepatitis B virus.
  • The inner core of the virus is a protein shell referred to as the hepatitis B core antigen or “HBcAg,” which contains the hepatitis B virus DNA and enzymes used in viral replication.

Life Cycle of the Hepatitis B Virus

The hepatitis B virus has a complex life cycle. The virus enters the host liver cell and is transported into the nucleus of the liver cell. Once inside the nucleus, the viral DNA is transformed into a covalently closed circular DNA , which serves as a template for viral replication . New HBV virus is packaged and leaves the liver cell, with the stable viral cccDNA remaining in the nucleus where it can integrate into the DNA of the host liver cell, as well as continue to create new hepatitis B virus. Although the life cycle is not completely understood, parts of this replicative process are error prone, which accounts for different genotypes or genetic codes of the hepatitis B virus.

What Is Hepatitis B

Hepatitis B is caused by a virus that infects the liver. It is one of the most common vaccine-preventable diseases affecting travellers and can cause either acute or chronic infection.

About 90 to 95 percent of adults with acute hepatitis B infection will clear the virus on their own within six months, and develop lifelong protection against it.

Some people are unable to clear the virus, and develop chronic hepatitis B. Untreated chronic hepatitis B can later develop into serious health problems. Children under four years old are at particular risk of chronic hepatitis B, because only up to 10% will clear the virus.

What Happens After A Hepatitis B Infection

Some people carry the virus in their bodies and are contagious for the rest of their lives. They should not drink alcohol, and should check with their doctor before taking any medicines to make sure these won’t cause more liver damage.

Anyone who has ever tested positive for hepatitis B cannot be a blood donor.

Treatment Options For Hepatitis B

World Hepatitis Day 2020

Acute hepatitis B usually doesnt require treatment. Most people will overcome an acute infection on their own. However, rest and hydration will help you recover.

Antiviral medications are used to treat chronic hepatitis B. These help you fight the virus. They may also reduce the risk of future liver complications.

You may need a liver transplant if hepatitis B has severely damaged your liver. A liver transplant means a surgeon will remove your liver and replace it with a donor liver. Most donor livers come from deceased donors.

How Is It Treated

Acute hepatitis B: There are no drugs to treat acutehepatitis B. Doctors usually suggest rest, goodnutrition, and fluids. Some people may need to be inthe hospital.

Chronic hepatitis B: People with chronic hepatitis Bvirus infection should receive care from a provider whohas experience treating hepatitis B. These providerscan be:

  • Some internists or family medicine providers
  • Infection specialists
  • Gastroenterologists
  • Hepatologists

If you have chronic hepatitis B, get checked regularlyfor signs of liver disease. Discuss treatment with yourhealth care provider. Not every person with chronichepatitis B needs treatment. If you show no signs ofliver damage, your provider will continue to check youfor liver disease.

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.

What Are The Symptoms

  • Symptoms can take 2 to 6 months to appear.
  • Many people who are infected with hepatitis B have either no symptoms or only mild symptoms.
  • Symptoms of acute hepatitis B can include fatigue, loss of appetite, joint pain, abdominal pain, nausea, vomiting, fever, and dark urine. A small number of people will develop jaundice .
  • Some people develop chronic hepatitis B and most remain contagious for the rest of their lives. Chronic infection may lead to cirrhosis and/or liver cancer. Most people with chronic hepatitis B are unaware of their infection.

How Can I Avoid Getting Hepatitis B

Hepatitis B: Explained

There is a safe and effective vaccine that can protect you from getting hepatitis B. The vaccine is usually given in three doses over a six month period. The vaccine will give you long-lasting protection. A combined vaccine for hepatitis A and hepatitis B is also available.

Other ways to protect yourself or your loved ones include:

  • Adopt safe sex practices.
  • Avoid sharing personal hygiene items
  • If you have been exposed to the hepatitis B virus , an injection of hepatitis B immune globulin may help protect you.
  • If you are pregnant, make sure you are screened for hepatitis B. If the test result shows that you have the virus, make sure your baby receives the free hepatitis B vaccine. If you have hepatitis B, breastfeeding is safe if the baby has received both protective antibody called immune globulin, and the first dose of hepatitis B vaccine within the first 12 hours of life. Talk to your doctor about having your newborn immunized .
  • If you decide to have a tattoo, piercing, manicure or pedicure, ensure that the facility uses single-use needles and inks and/or follows proper sterilization procedures.

What Should You Know About Hepatitis B Before You Travel

Hepatitis B is quite common in China and other Asian countries, where as many as 1 in 12 people have the virus, though many dont know it. Before traveling to those places, you should make sure youve been vaccinated against the virus.

In addition to getting the vaccine, you can take these additional precautions to reduce your risk of contracting the virus:

  • Refrain from taking illegal drugs.
  • Always use latex or polyurethane condoms during sex.
  • Make sure new, sterile needles are used during all piercings, tattoos and acupuncture sessions.
  • Avoid direct contact with blood and bodily fluids.
  • Know the HBV status of all your sexual partners.
  • Ask your doctor about possible vaccination before you travel to a place where hepatitis B is common.

A note from Cleveland Clinic

Hepatitis B is a liver disease that can cause serious damage to your health. One reason that is dangerous is that it can easily go undetected for years while damaging your liver. Talk with your healthcare provider about being tested for hepatitis B if you have any reason to believe that you were not vaccinated or if you have engaged in risky behavior. If you do test positive, follow the directions from your healthcare provider so that you can live a longer, healthier and happier life.
