How Does A Person Get Hepatitis B

Can Hepatitis B Be Prevented

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

The hepatitis B vaccine is one of the best ways to control the disease. It is safe, effective and widely available. More than one billion doses of the vaccine have been administered globally since 1982. The World Health Organization says the vaccine is 98-100% effective in guarding against the virus. Newborns should be vaccinated.

The disease has also been more widely prevented thanks to:

  • Widespread global adoption of safe blood-handling practices. WHO says 97% of the blood donated around the world is now screened for HBV and other diseases.
  • Safer blood injection practices, using clean needles.
  • Safe-sex practices.

You can help prevent hepatitis B infections by:

  • Practicing safe sex .
  • Never sharing personal care items like toothbrushes or razors.
  • Getting tattoos or piercings only at shops that employ safe hygiene practices.
  • Not sharing needles to use drugs.
  • Asking your healthcare provider for blood tests to determine if you have HBV or if you are immune.

Who Should Be Vaccinated For Hepatitis B

All newborns should be vaccinated. Also, people who are under 18 who were not vaccinated at birth should also get the vaccine. Other groups who should be sure to be vaccinated are those in certain high-risk categories, such as:

  • People who have more than one sexual partner.
  • Men who have sex with men.
  • Adults with diabetes.
  • Sexual partners of infected people and people who share households with infected individuals.
  • People who are exposed to blood and other bodily fluids, including healthcare and public safety professionals, and people who work in jails and other places taking care of people who cant take care of themselves.

Hepatitis B Symptoms & Treatment

FAST FACTS

  • Hepatitis B is a virus found in infected blood, semen and vaginal fluids.
  • Its a sexually transmitted infection that can be passed on through unprotected sex. You can also get it from contaminated needles and syringes. Its also commonly passed on from a mother to her baby during birth.
  • There is a vaccine to prevent hepatitis B, which is routinely offered to infants as well as at-risk groups.
  • You can prevent hepatitis B by practising safer sex, never sharing needles and syringes, and avoiding unlicensed tattoo parlours and acupuncturists.
  • Most people dont need treatment for acute hepatitis B. If the infection becomes chronic, there is no cure, but it can be managed with treatment.

How Do I Avoid Getting Sick

These tips will help protect you and your family from Hepatitis A:

  • Wash your hands after using the washroom and changing diapers, and before preparing or eating food.
  • When travelling, especially to developing countries:
  • drink water from a safe supply
  • avoid ice cubes in drinks
  • eat only freshly cooked food
  • avoid non-peelable raw fruit or vegetables
  • Talk to your doctor about getting a Hepatitis A vaccination before travelling.
  • Cook food to a safe internal temperature using a digital thermometer.
  • If you think that you have been exposed to the Hepatitis A virus, see your doctor immediately. Vaccination can prevent the onset of symptoms if given within two weeks of exposure.
  • If you have been diagnosed with Hepatitis A, or any other gastrointestinal illness, do not prepare food or pour water for other people.
  • Also, these safe food practices will reduce your risk of contracting Hepatitis A and other foodborne illnesses.

    How Do I Get Hepatitis A

    Know The ABC

    Hepatitis A is spread through close contact with an infected person, or by eating hepatitis A contaminated food or drinking water. Because the virus is found in the stool of infected people, eating food prepared by an infected person, who does not wash his/her hands properly after using the washroom, is one way of getting the virus.

    Eating raw or undercooked seafood and shellfish from water polluted with sewage, or eating salad greens that are rinsed in contaminated water are other ways of becoming infected. Sharing drug-use equipment, or having sexual contact with an infected person can also give you hepatitis A.

    While often considered to be a travellers disease, hepatitis A can be contracted in Canada. Hepatitis A outbreaks or scares in Canada are most often associated with infected food handlers in restaurants and grocery stores or with contaminated produce.

    Diagnosis Of Hepatitis B

    Blood tests are available to determine if you are or have been infected with hepatitis B. It may take 6 months from the time of infection before a blood test can detect antibodies to hepatitis B, so follow-up testing may be required. During this 6-month period, until you know whether you are infected or not, take action to prevent potential infection of other people.

    There are also tests that can assess liver damage from hepatitis B. The interpretation of these tests can be complicated and specialist advice is needed, so talk to your doctor.

    All pregnant women are tested for hepatitis B. If you are found to have chronic hepatitis B, your doctor can help reduce the risk of transferring the infection to your newborn child.

    How Long Before I Have Symptoms

    Many people have mild symptoms or no symptoms, which is why hepatitis is sometimes called a √Ęsilent√Ę disease.

    Hepatitis A. The symptoms usually show up 2 to 6 weeks after the virus enters your body. They usually last for less than 2 months, though sometimes you can be sick for as long as 6 months.

    Some warning signs that you may have hepatitis A are:

    Hepatitis B. The symptoms are the same as hepatitis A, and you usually get them 3 months after you’re infected. They could show up, though, anywhere from 6 weeks to 6 months later.

    Sometimes the symptoms are mild and last just a few weeks. For some people, the hep B virus stays in the body and leads to long-term liver problems.

    Hepatitis C. The early symptoms are the same as hepatitis A and B, and they usually happen 6 to 7 weeks after the virus gets in your body. But you could notice them anywhere from 2 weeks to 6 months later.

    For about 25% of people who get hep C, the virus goes away on its own without treatment. In other cases, it sticks around for years. When that happens, your liver might get damaged.

    Remember, it’s possible to spread all the types of hepatitis even if you don’t show any signs of being sick.

    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.

    How Common Is It

    In 2006, the Public Health Agency of Canada reported the incidence of HBV as 2.0 cases for every 100,000 or about 650 cases reported annually in Canada. In the year 2013, the incident rate was 0.5 per 100,000 . Incidence of the disease varies from region to region but has been declining due to increasing use of the vaccine and universal immunization programs.

    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.

    How long does HBV survive outside the body?

    HBV can survive outside the body and remains infectious for at least 7 days .

    What should be used to clean environmental surfaces potentially contaminated with HBV?

    Any blood spills should be disinfected using a 1:10 dilution of one part household bleach to 10 parts of water. Gloves should be worn when cleaning up any blood spills.

    Who is at risk for HBV infection?

    The following populations are at increased risk for becoming infected with HBV:

    • Infants born to infected mothers
    • Sex partners of infected people
    • Men who have sex with men
    • People who inject drugs
    • Household contacts or sexual partners of known people with chronic HBV infection

    • having vaginal, anal, or oral sex

    • sharing toothbrushes and razors

    • sharing needles for shooting drugs, piercings, tattoos, etc.

    • getting stuck with a needle that has the Hep B virus on it.

    Hepatitis B can also be passed to babies during birth if their mother has it.

    Hepatitis B isnt spread through saliva , so you CANT get hepatitis B from sharing food or drinks or using the same fork or spoon. Hepatitis B is also not spread through kissing, hugging, holding hands, coughing, sneezing, or breastfeeding.

    How Hepatitis B Is Spread

    Symptoms of Hepatitis B

    The hepatitis B virus is found in the blood and bodily fluids, such as semen and vaginal fluids, of an infected person.

    It can be spread:

    • from a mother to her newborn baby, particularly in countries where the infection is common
    • within families in countries where the infection is common
    • by having sex with an infected person without using a condom
    • by having a tattoo, body piercing, or medical or dental treatment in an unhygienic environment with unsterilised equipment

    Hepatitis B is not spread by kissing, holding hands, hugging, coughing, sneezing or sharing crockery and utensils.

    What Does The Government Do To Protect Me

    Hepatitis B: Explained

    In Canada, several government organizations work together every day to keep your food safe:

    • Health Canada makes food safety standards and policies to help minimize the risk of foodborne illnesses.
    • The Canadian Food Inspection Agency enforces these policies and standards and carries out inspections to make sure the food industry meets its food safety responsibilities. The CFIA works with Health Canada to make sure that foodborne illness is detected early and warnings go out to the public quickly.
    • The Public Health Agency of Canada studies the incidence and causes of diseases in Canada, conducts outbreak surveillance, and coordinates outbreak response.

    The Government of Canada works very hard to protect your health and safety:

    • We are carrying out a five-year Food and Consumer Safety Action Plan, to strengthen and modernize Canada’s safety system and make sure you can have confidence in the quality and safety of the food, health and consumer products you buy.
    • We are investing $75 million more in Canada’s food safety system to hire more inspectors, update lab technology, and improve communication with Canadians.
    • We support and participate in public awareness campaigns about safe food practices, like the Canadian Partnership for Consumer Food Safety Education’s Be Food Safe program, which encourages Canadian consumers to think of food safety at every step of the food handling process, from shopping for groceries to re-heating leftovers.

    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.

    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.

    Can You Be A Blood Or Organ Donor

    People with hepatitis C cant currently donate blood. The American Red Cross eligibility guidelines prohibit people who have ever tested positive for hepatitis C from donating blood, even if the infection never caused symptoms.

    According to the Department of Health and Human Services , information on organ donation, those with underlying medical conditions shouldnt rule themselves out as organ donors. This reflects new guidelines for organ donation announced by the HHS.

    People with HCV are now able to be organ donors. This is because advances in testing and medical technology can help the transplant team determine which organs or tissues can be safely used for transplantation.

    What Are The Symptoms Of Hepatitis A

    Hepatitis B vaccine: Safety and side effects

    Not all people infected with hepatitis A virus will have symptoms. Pre-school children often have no symptoms, and, in general, children will have milder symptoms than adults. Symptoms may occur 15 to 50 days from the time you first come in contact with the hepatitis A virus.

    When you first become infected with the hepatitis A virus it is called acute infection. Typical symptoms of an acute hepatitis A infection include fatigue, nausea and vomiting, abdominal discomfort, jaundice , dark urine, low-grade fever and loss of appetite.

    The older you are when you get hepatitis A, the more likely that you will experience more severe symptoms. Some people feel sick for one to two weeks, while in others the symptoms may last several months. Hepatitis A rarely causes death. However, persons with pre-existing chronic liver disease, including chronic hepatitis B and C, are at increased risk of serious complications from this infection.

    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.
