Is Hepatitis B Contagious
Hepatitis B is highly contagious. It spreads through contact with infected blood and certain other bodily fluids. Although the virus can be found in saliva, its not spread through sharing utensils or kissing. It also doesnt spread through sneezing, coughing, or breastfeeding. Symptoms of hepatitis B may not appear for 3 months after exposure and can last for 212 weeks. However, you are still contagious, even
To screen for hepatitis B, your doctor will perform a series of blood tests.
How Is Hepatitis B Prevented
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
Healthy Habits
After Exposure to Hepatitis B
Reducing The Risk Of Hepatitis B
Simple steps that everyone can take to protect themselves against hepatitis B include:
- Making sure you and your children are immunised this is the best protection.
- Using condoms every time you have anal or vaginal sex with new partners until you both get a check-up .
- Avoiding oral sex if you or your partner have herpes, ulcers or bleeding gums it is unlikely that you will contract hepatitis through oral sex unless blood is present.
- Choosing to have any body piercing or tattooing done by an experienced practitioner who follows good sterilisation and hygiene practices, and who works at premises registered by the local council.
- Wearing single-use gloves if you give someone first aid or need to clean up blood or body fluids.
- Never sharing needles and syringes or other equipment , if you inject drugs. Always use sterile needles and syringes. These are available from needle and syringe programs and some pharmacists. Always wash your hands before and after injecting.

Hepatitis B is a liver disease caused by the hepatitis B virus . The virus interferes with the functions of the liver and causes pathological damage. A small percentage of infected people cannot get rid of the virus and become chronically infected these people are at higher risk of death from cirrhosis of the liver and liver cancer.
HBV is spread by contact with blood or body fluids of an infected person the same way as the human immunodeficiency virus . However, HBV is 50 to 100 times more infectious than HIV.
The main ways of getting infected with HBV are:
- from mother to baby at the birth
- from child-to-child
- unsafe injections and transfusions
- unprotected sexual contact.
Worldwide, most infections occur from mother-to-child, from child-to-child , and from reuse of unsterilized needles and syringes. Before the widespread use of the hepatitis B vaccine, almost all children in developing countries used to become infected with the virus.

Should I Be Screened For Hepatitis B
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 dont have symptoms and dont 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.
Your doctor may recommend screening for hepatitis B if you9,14
- 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
- didnt 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
- 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
Treatments For Hepatitis B
Treatment for hepatitis B depends on how long you have been infected for.
If you have been exposed to the virus in the past few days, emergency treatment can help stop you becoming infected.
If you have only had the infection for a few weeks or months , you may only need treatment to relieve your symptoms while your body fights off the infection.
If you have had the infection for more than 6 months , you may be offered treatment with medicines that can keep the virus under control and reduce the risk of liver damage.
Chronic hepatitis B often requires long-term or lifelong treatment and regular monitoring to check for any further liver problems.

What Is Involved In A Liver Transplant
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.
What Is Chronic Hepatitis B
Doctors refer to hepatitis B infections as either acute or chronic:
- An acute HBV infection is a short-term illness that clears within 6 months of when a person is exposed to the virus.
- A person who still has HBV after 6 months is said to have a chronic hepatitis B infection. This is a long-term illness, meaning the virus stays in the body and causes lifelong illness. An estimated 850,000 to more than 2 million people in the U.S. have chronic HBV.
The younger someone is when infected, the greater the chances for chronic hepatitis B.

Complications Of Hepatitis B
A small proportion of people who become infected with the hepatitis B virus develop a long-term hepatitis B infection. They may have the virus in their bloodstream for most of their life without realising they are infected.
People with chronic hepatitis B infection may not notice any health problems until they develop liver problems such as liver disease or liver cancer later in life. Treatment for hepatitis B is essential because it is not possible to be a healthy carrier of the hepatitis B virus. Chronic hepatitis B infection occurs more commonly in some communities, including:
- Aboriginal and Torres Strait Islander communities.
- In people from parts of the world where hepatitis B is more common, such as:
- North-East Asia
- Sub-Saharan Africa.
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 health care 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.

If I Have Hepatitis B And Feel Healthy Do I Need To Keep Going To My Doctor
Chronic hepatitis B is a silent disease because often no symptoms appear until your liver is severely damaged. Although many people with chronic hepatitis B have an inactive disease and will remain healthy, about one in four will have an active disease that may lead to cirrhosis, liver failure, and liver cancer.
Because hepatitis B has no symptoms until your liver is badly damaged, a blood test is the only way for your doctor to find out if your hepatitis B is active or inactive, and to offer treatment, if needed. To help your doctor monitor how your disease behaves over time, you will need lifelong repeat blood tests every six to 12 months. Some tests, such as HBV DNA may need to be done more frequently . No treatment is required while the virus is inactive, but you should continue to get regular blood tests from your doctor to monitor your liver disease.
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.

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.
How Do Doctors Treat Hepatitis B
Doctors typically dont 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 persons liver, a doctor may prescribe antiviral medicines to lower the chances of liver damage and complications.
Medicines that you take by mouth include
A medicine that doctors can give as a shot is peginterferon alfa-2a .
The length of treatment varies. Hepatitis B medicines may cause side effects. Talk with your doctor about the side effects of treatment. Tell your doctor before taking any other prescription or over-the-counter medicines.
For safety reasons, you also should talk with your doctor before using dietary supplements, such as vitamins, or any complementary or alternative medicines or medical practices.

Can Hepatitis B Be Treated
If you know you have been exposed to the hepatitis B virus in the previous seven days or less, you can receive an injection of hepatitis B immune globulin that may prevent you from developing the disease. Besides this, there is no treatment for acute hepatitis B.
If you have chronic hepatitis B, two types of treatment exist interferon which is a medication administered by a needle, and antiviral medicines that are taken by mouth. Current approved hepatitis B oral medications include lamivudine, adefovir, telbivudine, tenofovir, and entecavir. These treatments do not provide a cure, but they offer control of the virus so that further damage to your liver can be prevented. When and how to treat your hepatitis B is a decision between you and your doctor. Availability of the medications listed above may vary from province to province based on provincial government drug plans and individual insurance plans.
Treatment For Suspected Exposure
Anyone who has had potential exposure to HBV can undergo a postexposure prophylaxis protocol.
This consists of HBV vaccination and hepatitis B immunoglobin . Healthcare workers give the prophylaxis after the exposure and before an acute infection develops.
This protocol will not cure an infection that has already developed. However, it decreases the rate of acute infection.

Treatment Options For Hepatitis B
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.
