Is Hepatitis A Virus Or Bacteria

Preventing Foodborne Illness At Home

Hepatitis | Pathophysiology of Viral Hepatitis

Hepatitis A can have serious health consequences. The CDC advises the post-exposure prophylaxis described above for unvaccinated persons who have consumed any products contaminated by the hepatitis A virus.

To prevent hepatitis A contamination or transmission, consumers should always practice safe food handling and preparation measures by following the steps below:

  • Wash hands with warm water and soap for at least 20 seconds before and after handling raw foods.
  • Thoroughly wash hands after using the bathroom and changing diapers for protection against hepatitis A, as well as other foodborne diseases.
  • Wash the inside walls and shelves of the refrigerator, cutting boards and countertops, and utensils that may have contacted contaminated foods then sanitize them with a solution of one tablespoon of chlorine bleach to one gallon of hot water dry with a clean cloth or paper towel that has not been previously used.
  • Wash hands with warm water and soap following the cleaning and sanitation process.
  • Consumers can also submit a voluntarily report, a complaint, or adverse event related to a food product.

Symptoms Of Hepatitis A

You can become ill any time between 2 and 4 weeks after coming into contact with the hepatitis A virus.

The average incubation period for the virus is 28 days.

Many infected people, particularly children less than 5 years old, show few or no symptoms.

For older children and adults, the symptoms of hepatitis A include:

  • yellow skin and eyes .

Symptoms may last for several weeks. Most people fully recover from hepatitis A infection.

A single infection of hepatitis A leads to lifelong immunity. Prior infection with hepatitis B or hepatitis C does not offer immunity for hepatitis A.

How Can I Prevent Spreading Hepatits A To Others

If you have hepatitis A, you can reduce your chance of spreading the infection by washing your hands with warm, soapy water after using the toilet and before fixing or eating food. While you are sick, avoid close contact with others, and donât prepare food or serve food to others. Also, tell your doctor, dentist, and other health care professionals that you have hepatitis A.

Talk with a blood donation center before you donate blood. If you had hepatitis A when you were younger than 11, you may be able to donate blood. If you had hepatitis A when you were age 11 or older, you should not donate blood.

You are most contagiousâable to spread the virus to othersâduring the 2 weeks before you have symptoms. You may be contagious for up to 3 weeks after you develop symptoms. Children are often contagious longer than adults.

Hepatitis A Immunisation Is Recommended For High

In Victoria, the vaccine is recommended for:

  • people travelling to places where hepatitis A is common
  • people whose work puts them at increased risk of infection including:
  • plumbers and sewage workers
  • people who work with children
  • people who work with people with developmental disabilities
  • people with developmental disabilities
  • people with liver disease or people who have had a liver transplant or have chronic hepatitis B or hepatitis C
  • people who have anal intercourse
  • people who inject drugs
  • inmates of correctional facilities .
  • Remember that immunisation against hepatitis A does not protect you against hepatitis B or hepatitis C.

    Managing Injection Site Discomfort

    Division of Viral Hepatitis Home Page

    Many vaccine injections may result in soreness, redness, itching, swelling or burning at the injection site for one to 2 days. Paracetamol might be required to ease the discomfort. Sometimes a small, hard lump at the injection site may persist for some weeks or months. This should not be of concern and requires no treatment.

    Treatment is vital to help improve the prognosis of a patient once they develop this bacterial infection. Since this disease is caused by a bacterium, the patient needs to be treated with an appropriate antibiotic to help kill off the bacteria, which will then help to ease the symptoms. The majority f patients who are treated with the right dose of antibiotics tend to make a full recovery within the first ten days following the initial development of their symptoms.

    Hepatitis A Vaccine And International Travel

    Who should get the hepatitis A vaccine before traveling internationally?

    All unvaccinated people, along with those who have never had hepatitis A, should be vaccinated before traveling to countries where hepatitis A is common. Travelers to urban areas, resorts, and luxury hotels in countries where hepatitis A is common are still at risk. International travelers have been infected, even though they regularly washed their hands and were careful about what they drank and ate. Those who are too young or cant get vaccinated because of a previous, life-threatening reaction to the hepatitis A vaccine or vaccine component should receive immune globulin. Travelers to other countries where hepatitis A does not commonly occur are not recommended to receive hepatitis A vaccine before travel.

    How soon before travel should I get the hepatitis A vaccine?

    You should get the first dose of hepatitis A vaccine as soon as you plan international travel to a country where hepatitis A is common. The vaccine will provide some protection even if you get vaccinated closer to departure. For older adults , people who are immunocompromised, and people with chronic liver disease or other chronic medical conditions the health-care provider may consider, based on several factors, giving an injection of immune globulin at the same time in different limbs.

    • Symptoms range from none to very severe.

    • Affected people may have a poor appetite, nausea, vomiting, fever, pain in the upper right part of the abdomen, and jaundice.

    • Doctors do blood tests to diagnose hepatitis and identify its cause.

    • Vaccines can prevent hepatitis A, B, and E .

    • Usually, specific treatment is not needed.

    After you discuss your symptoms with your doctor, they may order a blood test to check for the presence of a viral or bacterial infection. A blood test will reveal the presence of the hepatitis A virus.

    Some people have only a few symptoms and no signs of jaundice. Without visible signs of jaundice, its hard to diagnose any form of hepatitis through a physical examination. When symptoms are minimal, hepatitis A can remain undiagnosed. Complications due to a lack of diagnosis are rare.

    Pregnancy And Hepatitis A Immunisation

    Hepatitis A immunisation is not usually recommended for women who are pregnant although vaccination might be recommended in some situations.

    Speak with your doctor if you are not immune to hepatitis A and you are at increased risk of infection or if you have a pre-existing medical condition such as liver disease.

    Similarities Among Hepatitis A And Typhoid Fever

    Even though Hepatitis A is a viral infection and Typhoid is caused by a bacterium that infiltrates the human body, certain characteristics are shared among the two infections.

    Firstly, the methods of transmission for these two diseases share similar characteristics. In particular, it has been found that the virus that causes Hepatitis A and the bacteria that leads to the Typhoid infection can contaminate water and food. Thus, both of these infections can be transmitted to a person when they eat food that has been contaminated or when they drink water with traces of these pathogens.

    Furthermore, these two diseases also share the same vaccine. In Canada, the most commonly used hepatitis a and typhoid vaccine is known as Vivaxim. This particular vaccine is effective in preventing both Hepatitis A and the Typhoid bacterial infection. The vaccine is recommended only for patients that are over the age of 12. A single dose of the Vivaxim vaccine provides adequate protection, which should be administered to individuals before they travel to locations where these conditions are common.

    It should be noted however, that additional vaccines may be required to provide a patient with longer-term protection against the Hepatitis A viral infection.

    Hepatitis A Transmission

    Hepatitis A is a type of liver infection caused by a virus termed hepatitis A . Symptoms, if they occur, start about 2 to 6 weeks after exposure to HAV. About 80% of adults have symptoms while children seldom show symptoms. Symptoms of hepatitis A may include the following:

    • Nausea and/or vomiting
    • Jaundice
    • Joint pain

    Diagnosis Of Acute Viral Hepatitis

    What is Viral Hepatitis?
    • Blood tests

    Doctors suspect acute viral hepatitis based on symptoms. During the physical examination, a doctor presses on the abdomen above the liver, which is tender and somewhat enlarged in about half of the people with acute viral hepatitis.

    Doctors suspect fulminant hepatitis if

    • People are very ill and develop jaundice very quickly.

    • Mental function quickly deteriorates.

    • Blood tests to determine how quickly blood clotsâprothrombin time or international normalized ratio âare abnormal.

    • People who have liver disease start worsening rapidly.

    These blood tests can detect parts of specific viruses or specific antibodies produced by the body to fight the viruses. involves white blood cells that travel through the bloodstream and into tissues, searching for and attacking microorganisms and… read more â are proteins produced by the immune system to help defend the body against attack by viruses and other foreign invaders.)

    To determine whether the cause may be something other than a virus, the doctor may ask whether people take any drugs that can cause hepatitis and how much alcohol they drink.

    Occasionally, if the diagnosis is unclear, a liver biopsy is done: A sample of liver tissue is removed with a needle and examined.

    When To Contact A Medical Professional

    Seek care immediately if you:

    • Have symptoms from too much acetaminophen or other medicines. You may need to have your stomach pumped
    • Vomit blood
    • Have bloody or tarry stools
    • Are confused or delirious
    • You have any symptoms of hepatitis or believe that you have been exposed to hepatitis A, B, or C.
    • You cannot keep food down due to excessive vomiting. You may need to receive nutrition through a vein .
    • You feel sick and have travelled to Asia, Africa, South America, or Central America.

    How Do Doctors Diagnose Hepatitis A

    Doctors diagnose hepatitis A based on symptoms and a blood test. A health care professional will take a blood sample from you and send the sample to a lab. A blood test will detect antibodies to the hepatitis A virus called immunoglobulin M antibodies and show whether you have acute hepatitis A. If the blood test finds antibodies to the hepatitis A virus that are not IgM antibodies, then you are immune to hepatitis A, due to either past hepatitis A infection or hepatitis A vaccination.

    How Is Hepatitis A Diagnosed

    Hepatitis A can only be diagnosed through a series of blood tests. While a physician can conduct a physical examination and ask the patient about their symptoms, they will not be able to diagnose the patient with the infection without requesting blood tests. The blood tests will look for Immunoglobulin M antibodies against the Hepatitis A virus. When these antibodies are found in the patients blood, and their symptoms correspond with the symptoms associated with the infection, then the physician can diagnose the patient with Hepatitis A.

    What Do I Do If I Find Out I Have Viral Hepatitis

    After learning from your doctor that you have hepatitis, your first step will be to learn more about the virus. Read government resources, like the websites listed below, to find current, scientific information. Adopting a healthy lifestyle is important to prevent the virus from becoming serious. Dont drink or misuse drugs because they are hard on your liver. Get plenty of rest, eat healthy foods, and exercise. Work to protect others by not donating blood or participating in risky behaviors, including sharing needles when using drugs or having unprotected sex.

    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.

    How is hepatitis B spread?

    HBV is spread through contact with infected blood and body fluids including semen and vaginal fluid.

    Symptoms Of Acute Viral Hepatitis

    Acute viral hepatitis can cause anything from a minor flu-like illness to fatal liver failure Liver Failure Liver failure is severe deterioration in liver function. Liver failure is caused by a disorder or substance that damages the liver. Most people have jaundice , feel tired… read more . Sometimes there are no symptoms. The severity of symptoms and speed of recovery vary considerably, depending on the particular virus and on the person’s response to the infection. Hepatitis A and C often cause very mild symptoms or none at all and may be unnoticed. Hepatitis B and E are more likely to produce severe symptoms. Infection with both hepatitis B and D may make the symptoms of hepatitis B even more severe.

    Symptoms of acute viral hepatitis usually begin suddenly. They include

    • A poor appetite

    People with acute viral hepatitis usually recover in 4 to 8 weeks, even without treatment. However, some people infected with hepatitis B or C develop chronic infections.

    Who Is At Risk

    The ABCs of Viral Hepatitis

    Anyone who has not been vaccinated or previously infected can get infected with the hepatitis A virus. In areas where the virus is widespread , most hepatitis A infections occur during early childhood. Risk factors include:

    • poor sanitation
    • living in a household with an infected person
    • being a sexual partner of someone with acute hepatitis A infection
    • use of recreational drugs
    • travelling to areas of high endemicity without being immunized.

    How Long Does It Last

    Hepatitis A can last from a few weeks to several months.

    Hepatitis B can range from a mild illness, lasting a few weeks, to a serious, life-long condition. More than 90% of unimmunized infants who get infected develop a chronic infection, but 6%10% of older children and adults who get infected develop chronic hepatitis B.

    Hepatitis C can range from a mild illness, lasting a few weeks, to a serious, life-long infection. Most people who get infected with the hepatitis C virus develop chronic hepatitis C.

    What Are The Other Health Challenges For People With Hepatitis Who Inject Drugs

    People with hepatitis who inject drugs often have several other health conditions at the same time, including mental illness and HIV/AIDS, thus requiring care from multiple health care providers. This is sometimes referred to as co-occurring disorders. Substance use disorder treatment is critical for PWID, as it can reduce risky behaviors that increase the chance of transmitting hepatitis. Research has shown that patients with hepatitis receiving medication-assisted treatment for their opioid addiction can be safely treated with antiviral medications.5

    To enhance HCV care, NIDA is examining coordinated care models that utilize case managers to integrate HCV specialty care with primary care, substance use disorder treatment, and mental health services so that these patients get treatment regimens that address all of their health care needs. The Health Resources and Services Administrations Ryan White HIV/AIDS Program developed a free, online curriculum about HIV/hepatitis C for healthcare providers and healthcare staff to increase knowledge about co-infection among people of color in the United States.
