What Causes Hepatitis B
The hepatitis B virus causes hepatitis B. The hepatitis B virus spreads through contact with an infected persons 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 werent 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 persons razor, toothbrush, or nail clippers
You cant 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 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
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 Do You Get Hepatitis B
The virus that causes hepatitis B lives in blood, semen, and other fluids in your body. You usually get it by having sex with someone who’s infected.
You also can get it if you:
- Have direct contact with infected blood or the body fluids of someone who’s got the disease, for instance by using the same razor or toothbrush as someone who has hepatitis B, or touching the open sores of somebody who’s infected.
- If you’re pregnant and you’ve got hepatitis B, you could give the disease to your unborn child. If you deliver a baby who’s got it, they need to get treatment in the first 12 hours after birth.

What Are The Medications For Hepatitis B
All of the following medications used to treat chronic hepatitis B are antiviral medications. They reduce the ability of the virus to reproduce in the body and give the liver a chance to heal itself. These drugs are not a cure for hepatitis B, but they do reduce the damage caused by the virus. Although these medications are similar in some ways, they differ in other important ways. Talk to your health care practitioner about the best medication for you.
Pegylated interferon alfa-2b
Pegylated interferon is used alone or in combination with other medications.
Nucleoside/nucleotide analogues
Nucleoside/nucleotide analogues are compounds that mimic normal building blocks for DNA. When the virus tries to use the analogues, it is unable to make new viral particles. Examples of these agents include adefovir , entecavir , lamivudine , Telbivudine and tenofovir .
Who Should Get The Hepatitis B Vaccine
All newborn babies should get vaccinated. You should also get the shot if you:
- Come in contact with infected blood or body fluids of friends or family members
- Use needles to take recreational drugs
- Have sex with more than one person
- Are a health care worker
- Work in a day-care center, school, or jail

What Is Viral Hepatitis
Viral hepatitis is an inflammation of your liver that’s caused by a virus. There are five types, but the most common ones in the U.S. are hepatitis A, B, and C. All of them affect your liver. Some of the symptoms are similar, but they have different treatments.
Hepatitis A. This type won’t lead to long-term infection and usually doesn’t cause any complications. Your liver heals in about 2 months. You can prevent it with a vaccine.
Hepatitis B. Most people recover from this type in 6 months. Sometimes, though, it causes a long-term infection that could lead to liver damage. Once you’ve got the disease, you can spread the virus even if you don’t feel sick. You won’t catch it if you get a vaccine.
Hepatitis C. Many people with this type don’t have symptoms. About 80% of those with the disease get a long-term infection. It can sometimes lead to cirrhosis, a scarring of the liver. There’s no vaccine to prevent it.
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 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 Is The Follow
If an individual has acute hepatitis B, a health care practitioner will draw blood and examine the person periodically to see if the infection is resolving. If the person develops chronic hepatitis B, they will need periodic examinations and blood tests on an ongoing basis. If these tests indicate that the virus is actively damaging the liver, the healthcare practitioner may suggest a liver biopsy or begin antiviral therapy. The individual will also be given a vaccine against hepatitis A, which is an unrelated virus that may cause severe liver disease in people who already carry hepatitis B.
Chronic hepatitis B is associated with hepatocellular carcinoma. Fortunately, this is rare cancer. A blood test can be used to detect a marker for this cancer, or cancer can be detected by abdominal ultrasound. Persons with chronic hepatitis B are usually screened periodically for hepatocellular carcinoma, although it is not clear if this screening improves survival.

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.
Do I Need To Pay For Hepatitis B Immunisation
Vaccines covered by the NIP are free for people who are eligible. See the NIP Schedule to find out which vaccines you or your family are eligible to receive.
Eligible people get the vaccine for free, but your health care provider may charge a consultation fee for the visit. You can check this when you make your appointment.
If you are not eligible for free vaccine, you may need to pay for it. The cost depends on the type of vaccine, the formula and where you buy it from. Your immunisation provider can give you more information.

When To See A Healthcare Provider
If you develop any of the symptoms of chronic hepatitis, liver damage, or liver cancer, see your healthcare provider. It takes only a blood test to detect the presence of a hepatitis virus in your body .
A blood test also can determine which hepatitis virus you’re infected with, which will determine what your treatment should be .
Eating Diet And Nutrition For Hepatitis B
If you have hepatitis B, you should eat a balanced, healthy diet. Obesity can increase the chance of nonalcoholic fatty liver disease , and NAFLD can increase liver damage in people who have hepatitis B. Talk with your doctor about healthy eating and maintaining a healthy weight.
You should also avoid alcohol because it can cause more liver damage.

Causes Of Hepatitis B
Hepatitis B is spread through contact with blood that contains the hepatitis B virus. If infected blood or body fluids enter another persons bloodstream, that person may become infected.
The time from exposure to the hepatitis B virus to the appearance of the illness is 45 to 180 days.
Risky activities that can cause infection include:
- Sharing unsterile or unclean equipment for injecting drugs.
- Piercing the skin with equipment that is not properly cleaned, disinfected and sterilised.
- Sharing razor blades or toothbrushes.
- Coming into contact with infected blood through open cuts or the mucous membranes of another person.
- Having unprotected sex , especially if there is blood present.
Mothers who have hepatitis B can pass the virus to their babies or children at the time of birth or after birth. If the newborn baby is quickly immunised with 2 vaccines, they can be protected from getting hepatitis B.
All blood and blood products produced for medical purposes in Australia are carefully screened for hepatitis B and other blood-borne viruses. The risk of getting infected with hepatitis B from a blood transfusion is extremely low .
If I Have Hepatitis How Can I Avoid Giving It To Someone Else
For hepatitis A, one of the best things you can do is wash your hands a lot. That will keep the virus out of food and drinks.
If you have hepatitis B and C, you need to find ways to keep others from making contact with your blood. Follow these tips:
- Cover your cuts or blisters.
- Carefully throw away used bandages, tissues, tampons, and sanitary napkins.
- Don’t share your razor, nail clippers, or toothbrush.
- If your blood gets on objects, clean them with household bleach and water.
- Don’t breastfeed if your nipples are cracked or bleeding.
- Don’t donate blood, organs, or sperm.
- If you inject drugs, don’t share needles or other equipment.

What Should You Know About Pregnancy And Hepatitis B
A pregnant woman who has hepatitis B can pass the infection to her baby at delivery. This is true for both vaginal and cesarean deliveries.
You should ask your healthcare provider to test you for hepatitis B when you find out you are pregnant. However, while it is important for you and your healthcare provider to know if you do have hepatitis B, the condition should not affect the way that your pregnancy progresses.
If you do test positive, your provider may suggest that you contact another healthcare provider, a liver doctor, who is skilled in managing people with hepatitis B infections. You may have a high viral load and may need treatment during the last 3 months of your pregnancy. A viral load is the term for how much of the infection you have inside of you.
You can prevent your infant from getting hepatitis B infection by making sure that your baby gets the hepatitis B vaccine in the hours after they are born along with the hepatitis B immunoglobulin. These two shots are given in two different locations on the baby. They are the first shots needed.
Depending on the type of vaccine used, two or three more doses must be given, usually when the baby is 1 month old and then 6 months old, with the last by the time the baby is 1 year old. It is critical that all newborns get the hepatitis B vaccination, but even more important if you have hepatitis B yourself.
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.

How Is Hepatitis B Treated
Your healthcare provider will treat you based on what type of hepatitis B you have, acute or chronic.
Acute hepatitis B infections
If you develop an acute form of the condition, you probably wont need medical treatment. Instead, your doctor will likely suggest that you get plenty of rest, drink lots of fluids and maintain a healthy diet to support your body as it fights off the infection.
Chronic hepatitis B infections
If you have chronic hepatitis B, you might be a candidate for drug therapy. Usually, drug therapy is used only if you have active liver disease. There are seven drugs that are approved by the U.S. Food and Drug Administration to treat hepatitis B. Two are injectable forms of interferon, while the five other antivirals are tablets.
You will need to take these medications every day. They help by slowing the viruss ability to multiply in your system. This helps reduce swelling and liver damage. Youll need to be regularly monitored for early signs of liver damage and liver cancer. Your healthcare provider will want to see you once or twice a year.
When Should I Call The Doctor For Hepatitis B
- Nausea and vomiting that does not go away in 1-2 days
- The inability to keep down liquids
- A high fever or fever that persists more than 2 days
- Dark-colored urine
- Pain in the abdomen.
For severe symptoms including confusion or delirium go to a hospital emergency department.
You should also contact your health care practitioner if you think you may have been exposed to the hepatitis B virus.
If you have chronic hepatitis B infection and think you might be pregnant or if you are pregnant and think you have been exposed to hepatitis B inform health care practitioner right away.

Is Surgery A Treatment For Hepatitis B
There is no surgical therapy for hepatitis B.
If liver damage is so severe that the liver starts to fail, liver transplant may be recommended:
- Liver transplant is a major process and surgery with an extended recovery period.
- It also depends on the availability of a matching donor liver.
- If liver transplant becomes a possibility for an individual, a health care practitioner will discuss the risks and benefits with them.
How Do You Prevent Hepatitis C
Researchers have yet to develop a vaccine that prevents hepatitis C .
Just as you might not know you have hepatitis C, other people with the condition may not know they have it, either. But you can take a few key precautions to avoid contracting it:
- Avoid sharing needles.
- When getting piercings or tattoos, check to make sure the piercer or tattoo artist uses only sterile, unopened needles and ink.
- Avoid sharing nail clippers, razors, and toothbrushes.
- Use sterile gloves when caring for someone elses wound.
Since hepatitis C is transmitted through blood, you wont get it by sharing food and drinks with someone who has the condition or by hugging, touching, or holding hands.
Hepatitis C is not commonly transmitted through sexual contact. But using a condom or another barrier method when having sex can always help lower your chances of contracting a sexually transmitted infection.
Keep in mind that you can contract hepatitis C again, even if youve had it already.

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 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.
