Symptoms Of Hepatitis B
Many people with hepatitis B will not experience any symptoms and may fight off the virus without realising they had it.
If symptoms do develop, they tend to happen 2 or 3 months after exposure to the hepatitis B virus.
Symptoms of hepatitis B include:
- flu-like symptoms, including tiredness, a fever, and general aches and pains
- loss of appetite
- tummy pain
- yellowing of the skin and eyes
These symptoms will usually pass within 1 to 3 months , although occasionally the infection can last for 6 months or more .
Who Are Hepatitis B Carriers
Hepatitis B carriers are people who have the hepatitis B virus in their blood, even though they dont feel sick. Between 6% and 10% of those people whove been infected with the virus will become carriers and can infect others without knowing it. There are over 250 million people in the world who are carriers of HBV, with about 10% to 15% of the total located in India. Children are at the highest risk of becoming carriers. About 9 in 10 babies infected at birth become HBV carriers, and about half of children who are infected between birth and age 5 carry the virus. A blood test can tell you if you are a hepatitis B carrier.
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.

Hepatitis B In The United States
In the United States, about 862,000 people have chronic hepatitis B.6 Asian Americans and African Americans have higher rates of chronic hepatitis B than other U.S. racial and ethnic groups.10 Researchers estimate that about half of the people living with chronic hepatitis B in the United States are Asian Americans and Pacific Islanders.11 Chronic hepatitis B is also more common among people born in other countries than among those born in the United States.7
The hepatitis B vaccine has been available since the 1980s and, in 1991, doctors began recommending that children in the United States receive the hepatitis B vaccine. The annual rate of acute hepatitis B infections went down 88.5 percent between 1982 and 2015.12 In 2017, the annual number of hepatitis B infections rose in some states.13 Experts think the rise was related to increases in injection drug use. Injection drug use increases the risk of hepatitis B infection.
Reduce Your Chance Of Infection
You can reduce your chance of hepatitis B infection by
- not sharing drug needles or other drug materials
- wearing gloves if you have to touch another persons blood or open sores
- making sure your tattoo artist or body piercer uses sterile tools
- not sharing personal items, such as toothbrushes, razors, or nail clippers
- using a latex or polyurethane condom during sex

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 No Symptoms How Would I Know If I Have Hepatitis B
To confirm whether or not you have hepatitis B, you will need blood tests.
If you have at least one risk factor , you should ask your health care provider to be tested for hepatitis B. Also, you should be tested for hepatitis B if:
- you were born in a region where hepatitis B is more common, including Asia, Africa, southern and eastern Europe, the Pacific Islands, the Middle East, and the Arctic
- one or both of your parents immigrated from a region where hepatitis B is more common
- you live or travel to regions where hepatitis B is more common
- you have a family history of liver disease or liver cancer
- you have been in prison
- you are pregnant
- you have ever used injection drugs, even just once
- you have unexplained abnormal liver enzymes or if
- you receive medicines that suppress the immune system.

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 Can I Prevent Spreading Hepatitis B To Others
If you have hepatitis B, follow the steps above to avoid spreading the infection. Your sex partners should get a hepatitis B test and, if they arent infected, get the hepatitis B vaccine. You can protect others from getting infected by telling your doctor, dentist, and other health care professionals that you have hepatitis B. Dont donate blood or blood products, semen, organs, or tissue.

How Do Doctors Treat The Complications Of Hepatitis B
If chronic hepatitis B leads to cirrhosis, you should see a doctor who specializes in liver diseases. Doctors can treat the health problems related to cirrhosis with medicines, minor medical procedures, and surgery. If you have cirrhosis, you have an increased chance of liver cancer. Your doctor may order blood tests and an ultrasound or another type of imaging test to check for liver cancer.
If chronic hepatitis B leads to liver failure or liver cancer, you may need a liver transplant.
You Can Have It And Not Know It
What is hepatitis B?
Hepatitis B is a liver disease caused by the hepatitis B virus . HBV is far more infectious than HIV and can be prevented by a vaccine. People who have not been vaccinated may be at risk of getting infected.
About 95 percent of adults will recover within 6 months of becoming infected and as a result will develop lifelong protection against it. The remaining 5 percent are unable to clear the virus and will become chronically infected. Chronic hepatitis B infection is treatable.
It is estimated that less than 1 percent of Canada’s population is infected with either acute or chronic HBV. People who are infected before the age of 7 are at a higher risk of developing chronic infection. In 2011, the overall reported rate of acute hepatitis B infection in Canada was 0.6 reported cases per 100,000 people living in Canada.
Why is hepatitis B a health concern?
Many people infected with HBV do not know they have the virus because symptoms can take two to six months to appear and only about 50 percent of people develop symptoms. During this time, they can spread the infection to others. You may not know you have this infection until damage has already been done to your liver. Potential complications from chronic HBV infection include cirrhosis of the liver, liver failure, liver cancer and premature death.

Adults Recommended To Receive Hepb Vaccine:
- Persons at risk for infection by sexual exposure
- Sex partners of hepatitis B surface antigen positive persons
- Sexually active persons who are not in a long-term, mutually monogamous relationship
- Persons seeking evaluation or treatment for a sexually transmitted infection
- Men who have sex with men
How Can I Prevent The Spread Of Hepatitis B Virus
There are vaccines available to prevent HBV infection. The hepatitis B vaccine is provided free to babies, people born in 1980 or later and to specific at-risk groups, such as sexual and household contacts of someone living with HBV.
You can reduce the chance of passing this virus to others by doing the following:
- Talk to your health care provider if you are pregnant, as there is a risk of passing the virus on to your baby. This risk can be greatly reduced by giving your baby HBIg and the first dose of the hepatitis B vaccine series at birth. Antiviral medications may be recommended for you before you give birth to further reduce the risk of passing the virus to your baby
- Do not share equipment for drug snorting, smoking or injection, such as straws, pipes, spoons, cookers and needles
- Use a condom during vaginal or anal sex
- Do not donate your blood, semen, body organs or tissues
- Do not share razors, toothbrushes, dental floss, nail files or other personal care items or medical devices that could have tiny amounts of blood on them
- Keep all open cuts and sores bandaged until healed
- Ensure any equipment that comes in contact with your bodily fluids, such as those used for tattooing or piercing, is properly sterilized
- Use a bleach solution to clean areas of your home or personal items that could have blood on them. Mix 9 parts water to 1 part bleach

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.

How Is Hepatitis B Virus Spread
HBV is spread through contact with the blood and other body fluids of someone with HBV infection. Blood, semen and vaginal fluid contain the highest amounts of virus. Transmission can occur through the following:
- Sharing items that may have blood on them such as a toothbrush, dental floss or razor
- Unprotected vaginal or anal sex with a person living with HBV
- Sharing equipment for drug snorting, smoking or injection with someone living with HBV, such as straws, pipes, spoons, cookers and needles
- Being bitten by a person living with HBV when blood is present
- From a mother living with HBV to her baby before or during delivery
- Skin-piercing events such as tattoos, body piercing, acupuncture or electrolysis, if the equipment is contaminated with the virus
- Medical care received in places without proper infection control practices
- Blood transfusion or medical procedures done before 1970 in Canada

What Are The Types Of Hepatitis B
There are two types of hepatitis B infection: acute and chronic.
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.
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.
What Are Clinical Trials For Hepatitis B
Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.
Researchers are studying many aspects of hepatitis B, such as
- progression of hepatitis B and long-term outcomes
- new treatments for hepatitis B
- prevention of reactivated or worsening hepatitis B in people receiving cancer treatment

Extrahepatic Manifestations Of Hepatitis B
Extrahepatic manifestations of hepatitis B are present in 110% of HBV-infected patients and include serum-sicknesslike syndrome, acute necrotizing vasculitis , membranous glomerulonephritis, and papular acrodermatitis of childhood ., Although the pathogenesis of these disorders is unclear, immune complexmediated injury related to high level of HBV antigenemia is thought to be the cause.
The serum-sicknesslike syndrome occurs in the setting of acute hepatitis B, often preceding the onset of jaundice. The clinical features are fever, skin rash, and polyarteritis. The symptoms often subside shortly after the onset of jaundice, but can persist throughout the duration of acute hepatitis B. The course of this syndrome often parallels the duration and level of HBV viremia: rapid clearance of the virus leads to rapid resolution of the illness. This disorder resembles experimental serum sickness, in which immune complexes activate the complement pathways leading to complement-mediated injury. Patients with this syndrome have low complement levels and high-level circulating immune complexes containing HBV antigens and complement components.
Other immune-mediated hematological disorders, such as essential mixed cryoglobulinemia and aplastic anemia have been described as part of the extrahepatic manifestations of HBV infection, but their association is not as well-defined therefore, they probably should not be considered etiologically linked to HBV.
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 alcoholic beverages and tobacco products are crucial components in managing the disease.
You should also visit a doctor familiar with hepatitis B at least annuallythough 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.

Transmission Symptoms And Treatment
How is HBV transmitted?
HBV is transmitted through activities that involve percutaneous or mucosal contact with infectious blood or body fluids , including
- sex with an infected partner
- injection-drug use that involves sharing needles, syringes, or drug-preparation equipment
- birth to an infected mother
- contact with blood from or open sores on an infected person
- exposures to needle sticks or sharp instruments and
- sharing certain items with an infected person that can break the skin or mucous membranes , potentially resulting in exposure to blood.
