How Is Hepatitis B Diagnosed
There are three main ways to diagnose HBV infection. They include:
- Blood tests: Tests of the blood serum shows how your bodys immune system is responding to the virus. A blood test can also tell you if you are immune to HBV.
- Abdominal ultrasound: An ultrasound uses sound waves to show the size and shape of your liver and how well the blood flows through it.
- Liver biopsy: A small sample of your liver tissue is removed though a tiny incision and sent to a lab for analysis.
The blood test that is used to diagnose hepatitis B is not a test that you get routinely during a medical visit. Often, people whove become infected first learn they have hepatitis B when they go to donate blood. Blood donations are routinely scanned for the infection.
The virus can be detected within 30 to 60 days of infection. About 70% of adults with hepatitis B develop symptoms, which tend to appear an average of 90 days after initial exposure to the virus.
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.
Immunisation Against Hepatitis A
Immunisation is the best protection against hepatitis A infection and is recommended for people in high-risk groups, and for unvaccinated people who have been in close contact with someone who has hepatitis A.
Immunisation against hepatitis A includes a course of injections over a 6 to 12-month period. Healthy people 12 months of age and over receive 2 doses of hepatitis A vaccine, or 3 doses if the hepatitis A and hepatitis B vaccines are given as a combination.
You can complete any missed vaccine doses, even if the recommended time frame has passed. You do not need to start the vaccine course again.
If you are in close contact with someone who has hepatitis A be sure to have the hepatitis A vaccine if you have not already completed a vaccine course.
Babies under 12 months of age and people who have a weakened immune system who are also in close contact with a person with hepatitis A can have an injection of normal human immunoglobulin instead of the hepatitis A vaccine.
Protection against hepatitis A is available free of charge under the National Immunisation Program Schedule for Aboriginal and Torres Strait Islander children who live in high-risk areas .

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
Reducing The Risk Of Hepatitis A
Protecting yourself from hepatitis A
The most important action you can take to protect yourself against hepatitis A is to get vaccinated.
Practising strict personal hygiene is also essential to reducing the risk of hepatitis A. Steps you can take include:
- Wash your hands with soap and hot running water before handling food, after going to the toilet and after handling used condoms or having contact with nappies or the anal area of another person. Use a clean towel to dry your hands.
- Use barrier protection when engaging in oral-anal sex and avoid sex with someone who is infected with the hepatitis A virus.
- Vaccination may prevent illness if given within 2 weeks of contact with an infectious person.
- Clean bathrooms and toilets often, paying attention to toilet seats, handles, taps and nappy change tables.
- Boil your drinking water if it comes from an untreated source, such as a river.
- If you are travelling overseas, particularly to countries where hepatitis A is widespread, take special care to avoid hepatitis A. Before travelling, talk to your doctor about immunisation for protection.
Protecting others from hepatitis A
If you have hepatitis:
- Wash eating utensils in soapy water, and machine wash linen and towels.
Household contacts and sexual partners of an infectious person may need to be immunised.
All people who have hepatitis A should check with their doctor before returning to work or school.

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
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.

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.
Managing Fever After Immunisation
Common side effects following immunisation are usually mild and temporary . Specific treatment is not usually required.
There are a number of treatment options that can reduce the side effects of the vaccine such as giving extra fluids to drink and not overdressing if there is a fever.
Although routine use of paracetamol after vaccination is not recommended, if fever is present, paracetamol can be given check the label for the correct dose or speak with your pharmacist, especially when giving paracetamol to children.

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 partly 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 and an ultrasound or another type of imaging test to check for liver cancer. Finding cancer at an early stage improves the chance of curing the cancer.
Why Is The Hepatitis B Vaccine Important
Because of the vaccine, cases of acute hepatitis B have decreased by a lot in the United States. But chronic hepatitis B is still common up to 2.2 million people in the United States have it. Chronic hepatitis B can lead to serious liver problems and even death.
Getting vaccinated is the best way to prevent hepatitis B.
Hepatitis B is a liver disease caused by a virus. There are 2 types of hepatitis B:
- Acute hepatitis B
- Chronic hepatitis B
Many children who get acute hepatitis B dont have any symptoms, but most adults do. Symptoms may include:
- Fever
- Dark pee or clay-colored poop
- Pain in the muscles, joints, and stomach
- Jaundice
Acute hepatitis B symptoms usually last a few weeks but they can last as long as 6 months.
If the acute hepatitis B infection does not go away after 6 months, its considered a chronic hepatitis B infection. Most people who have chronic hepatitis B dont have symptoms at first. But chronic hepatitis B is a lifelong illness that can lead to serious and possibly deadly liver problems, like:
- Cirrhosis
- Liver cancer
- Liver failure
Hepatitis B spreads through blood, semen, or other body fluids. Hepatitis B can spread from mother to child during birth and when someone:
- Has sex with a person who has hepatitis B
- Touches the blood or open sores of a person who has hepatitis B
All children need to get the hepatitis B vaccine and some adults may need it, too.
Infants and children
Children need 3 doses of the vaccine at the following ages:

What Is Hepatitis B
Hepatitis B is a contagious liver disease caused by the hepatitis B virus. When a person is first infected with the virus, he or she can develop an acute infection. Acute hepatitis B refers to the first 6 months after someone is infected with the hepatitis B virus. This infection can range from a very mild illness with few or no symptoms to a serious condition requiring hospitalization. Some people are able to fight the infection and clear the virus.
For others, the infection remains and is chronic, or lifelong. Chronic hepatitis B refers to the infection when it remains active instead of getting better after 6 months. Over time, the infection can cause serious health problems, and even liver cancer.
Who Should Be Immunised Against Hepatitis B
Hepatitis B immunisation is recommended and funded for the following groups:
- all children up to their 18th birthday
- babies born to mothers with hepatitis B infection
- people who live in close contact with someone infected with hepatitis B
- anyone undergoing renal dialysis
- people who have hepatitis C infection, or who are HIV positive, or who have had a needle stick injury.
- anyone who has received immunosuppression therapy of at least 28 days or has had solid organ or bone marrow transplant.
Hepatitis B immunisation is also recommended, but not funded, for:
- workers who are likely to come into contact with blood products, or who are at increased risk of needlestick injuries, assault, etc.
- people who change sex partners frequently such as sex workers
- people who regularly receive blood transfusions such as people with haemophilia
- prison inmates
- current or recent injecting drug users
- migrants and travellers from or to areas with intermediate or high rates of hepatitis B such as the Asia and Pacific region.

Likehepatitis A, hepatitis B is an infectious, viral disease of the liver. Unlike hepatitis A, hepatitis B is primarily spread through sexual contact with an infected partner. Perinatal transmission of the disease from an infected mother to her unborn child is another major source of transmission in developing countries. Around the world, an estimated 350 million people are chronic carriers of hepatitis B.
Hepatitis B vaccinations have been commonplace in the United States since the early 1990’s. Ninety-five percent of children who receive a hepatitis B vaccination are sufficiently immunized against the disease and will remain largely protected for the rest of their lives. Children who are born to a hepatitis B infected mother are generally immunized at birth.
Several inactivated virus vaccines, including Recombivax HB, GenHevac B, Hepagene, and Engerix-B, can prevent hepatitis B. Twinrix is a vaccine against both hepatitis A and B. Hepatitis B vaccine may be given by itself or in the same shot with other vaccines. In the United States, infants receive 3 doses of hepatitis vaccines. CDC recommends anyone through 18 years of age who did not get the vaccine when they were younger should also be vaccinated. However, these vaccines can also carry serious consequences.
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.

Vaccination And Other Prevention Measures
Vaccination is a safe and effective way of preventing the spread of hepatitis B. Since 1985, the hepatitis B vaccine has been part of the national immunisation schedule. In 1988, New Zealand was one of the first countries to introduce universal infant hepatitis B immunisation.The vaccine is given to babies at age six weeks, three months, and five months. Babies born to mothers with hepatitis B receive an extra dose of the vaccine at birth as well as a dose of hepatitis B-specific immune globulin.In children and adolescents who did not receive the hepatitis B vaccine in the first year of life, the full three-dose course is recommended.Hepatitis B immunisation is recommended and publicly funded for all infants and children up to their 18th birthday, household and sexual contacts of people with acute or chronic hepatitis B, and certain other high-risk populations. Measures that can help prevent the spread of the hepatitis B virus include:
- Teaching children not to touch the blood or wounds of others
- Covering cuts, scratches, and grazes
- Not sharing personal items such as razors and toothbrushes
- Never sharing needles or syringes if you use intravenous drugs
- Practising safe sex, including the use of condoms
- Seek assurance that body piercing and tattooing needles and equipment are sterile.
