Causes Of Hepatitis A
Hepatitis A is caused by a virus. The virus can survive for several hours outside the body but persists on the hands and in food for even longer. It is resistant to heating and freezing.
The virus is spread when it enters the mouth, which can happen when hands, foods or other items are contaminated with the faeces of a person with hepatitis A. The disease can also be spread sexually by oral or anal contact.
A person with hepatitis A is infectious from 2 weeks before they show symptoms to one week after they become jaundiced .
If an infected person has no jaundice, they may pass on the virus until 2 weeks after they first have symptoms . Caution is advised beyond this period as the virus can be shed in stools for longer periods.
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 .
How Is Acute Hepatitis B Treated
Acute hepatitis B doesnt always require treatment. In most cases, a doctor will recommend monitoring your symptoms and getting regular blood tests to determine whether the virus is still in your body.
While you recover, allow your body to rest and drink plenty of fluids to help your body fight off the infection. You can also take an over-the-counter pain reliever, such as ibuprofen , to help with any abdominal pain you have.
See a doctor if your symptoms are severe or seem to be getting worse. You may need to take a prescription antiviral medication to avoid potential liver damage.
Like acute hepatitis B, chronic hepatitis B may not require medical treatment to avoid permanent liver damage. In some patients, monitoring symptoms and getting regular liver tests is appropriate.
Treatment generally involves antiviral medications, such as:
- peginterferon alfa-2a injections
- antiviral tablets, such as tenofovir or entecavir
Antiviral medications can help to reduce symptoms and prevent liver damage. But they rarely completely get rid of the hepatitis B virus. Instead, the goal of treatment is to have the lowest viral load possible. Viral load refers to the amount of a virus in a blood sample.
Theres no cure for hepatitis B, but the condition is easily preventable by taking a few precautions. Hepatitis B is often spread through sexual contact, shared needles, and accidental needle sticks.
You can reduce your risk of developing hepatitis B or spreading the virus to others by:

What Causes Hepatitis A
Hepatitis A is caused by infection with the hepatitis A virus. You get the virus when you unknowingly eat a small amount of infected feces. This can happen through person-to-person contact, or through eating or drinking contaminated food or water.
A person can have and spread hepatitis A, even if that person does not have any symptoms. You are most likely to get hepatitis A from another person when:
- A person who has the virus does not wash their hands properly after going to the bathroom
- A parent does not wash their hands properly after changing the diaper of an infected child
- A caregiver does not wash their hands properly after cleaning up the stool of an infected person
- A person has sex with a person who has the virus
You can also get infected with hepatitis A by eating contaminated food or drinking contaminated water. Contaminated food and water are more common in developing countries. When traveling in areas where hepatitis A is common, avoid eating raw fruits and vegetables, shellfish, ice, and untreated water.
Managing Injection Site Discomfort
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.

How Do I Know If I Am Infected With Viral Hepatitis
The number of new HBV and HCV infections has been declining in recent years, but the number of people living with chronic hepatitis infections is considerable, and deaths associated with untreated, chronic hepatitis infections have been on the rise. This is because most people dont know they are infected until the disease has begun to damage the liver, highlighting why screening for viral hepatitis is so important. People with a history of drug use are generally at higher risk, and should discuss their substance use with their health care provider.
Initial screening for HBV or HCV involves antibody tests, which show whether you have been exposed to the hepatitis virus, although not necessarily whether you are still infected. A positive antibody test should then be followed up with a test that measures the amount of virus in your blood. If this follow-up test is positive, then you should seek advice from a physician that specializes in viral hepatitis treatment. Because screening for hepatitis is so critical for linking people who test positive to the care they need, NIDA is studying new rapid HCV antibody tests that can be used in drug treatment settings.
The CDC recommends that people who inject drugs be tested for hepatitis B and C as part of routine medical care. To determine if you are at risk for contracting hepatitis, HHS has created an online assessment tool to help you find out.
Hepatitis A And E Symptoms
Hepatitis A and hepatitis E present with similar symptoms. The diseases may develop without any signs or symptoms, or symptoms may be nonspecific. If you experience any of the symptoms below for more than two weeks, make an appointment with a gastroenterologist.
There are three phases of hepatitis A and E, and symptoms may differ depending on the stage. Early in the disease, called the prodromal phase, symptoms may include:

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.
Sometimes The Infection Goes Away On Its Own
Acute hepatitis is C is a short-term illness that occurs within the first six months after being exposed to the virus. Like the human papillomavirus , early acute hepatitis C can clear on its own without treatment this happens about 25% of the time.
However, it’s more likely that the virus will remain in your body longer than six months, at which point it’s considered to be chronic hepatitis C infection.
“Being younger or a woman tends to be a factor in whether the virus clears on its own, and genetics may play a role,” Reau says. “But we can’t determine with certainty which people are certain to clear the infection and which aren’t.”

History And Physical Exam
To diagnose hepatitis, first your doctor will take your history to determine any risk factors you may have for infectious or noninfectious hepatitis.
During a physical examination, your doctor may press down gently on your abdomen to see if theres pain or tenderness. Your doctor may also feel to see if your liver is enlarged. If your skin or eyes are yellow, your doctor will note this during the exam.
What Is Hepatitis
Hepatitis is a disease that can cause inflammation of the liver. There are many causes of hepatitis, both infectious and non-infectious.
Infectious hepatitis can be caused by several different Hepatitis viruses. The most common in Canada are A, B and C, though of these three, only Hepatitis A can be transferred through contaminated food and water.
Hepatitis A can range in severity from a mild illness lasting a few weeks to a severe illness lasting several months. You can get the Hepatitis A virus by eating contaminated food or water or through contact with an infected person’s feces .

How Is Hav Spread
- Food handlers with HAV did not wash their hands after they used the bathroom.
- Drinking water that was not clean or eating raw shellfish that came from water that was not clean.
- Travel to areas in the world where hepatitis A is common or has an active outbreak.
- Daycare workers did not wash their hands after they changed a diaper.
- Sexual contact with someone who has hepatitis A, especially men who have sex with other men.
The 5 Types Of Viral Hepatitis
Viral infections of the liver that are classified as hepatitis include hepatitis A, B, C, D, and E. A different virus is responsible for each type of virally transmitted hepatitis.
Hepatitis A is always an acute, short-term disease, while hepatitis B, C, and D are most likely to become ongoing and chronic. Hepatitis E is usually acute but can be particularly dangerous in pregnant women.

Complications Of Hepatitis A
Around 10% of people who have had hepatitis A experience a relapse . Most people who have a relapse fully recover.
Hepatitis A does not cause chronic liver disease.
The severity of the disease is more severe in older age groups.
Complications of hepatitis A are rare, but the infection can lead to fulminant hepatitis. This is an acute form of hepatitis that can cause liver failure. The risk of death from fulminant hepatitis increases with age.
Can Bleach Or Cleaner Kill Hepatitis A
Disinfectant that contains bleach can kill the hepatitis A virus on hard non-porous surfaces like toilet seats. However, freezing does not kill HAV.
If you cook food that is contaminated for one minute at cooking temperatures higher than 185ºF , it will kill HAV. However, food can be contaminated after cooking, so it is very important to wash your hands well with soap and water.

What Are The Treatments For Hepatitis
Treatment for hepatitis depends on which type you have and whether it is acute or chronic. Acute viral hepatitis often goes away on its own. To feel better, you may just need to rest and get enough fluids. But in some cases, it may be more serious. You might even need treatment in a hospital.
There are different medicines to treat the different chronic types of hepatitis. Possible other treatments may include surgery and other medical procedures. People who have alcoholic hepatitis need to stop drinking. If your chronic hepatitis leads to liver failure or liver cancer, you may need a liver transplant.
What Is Hepatitis A
Hepatitis A, also called hep A, is a contagious liver infection caused by the hepatitis A virus. Some people have only a mild illness that lasts a few weeks. Others have more severe problems that can last months. You usually get the disease when you eat or drink something contaminated by poop from a person who has the virus.
The hepatitis A virus usually isnât dangerous. Almost everyone who has it gets better. But because it can take a while to go away, youâll need to take care of yourself in the meantime.

How Do Doctors Treat Hepatitis A
Treatment includes resting, drinking plenty of liquids, and eating healthy foods to help relieve symptoms. Your doctor may also suggest medicines to help relieve symptoms.
Talk with your doctor before taking any prescription or over-the-counter medicines, vitamins or other dietary supplements, or complementary or alternative medicinesany of these could damage your liver. You should avoid alcohol until your doctor tells you that you have completely recovered from hepatitis A.
See your doctor regularly to make sure your body has fully recovered. If you have symptoms for longer than 6 months, see your doctor again.
Are Alternative Medicines Available
Some people believe certain forms of alternative medicine help cure hepatitis C.
However, the National Center for Complementary and Integrative Health reports that there are no effective, research-proven forms of alternative treatment or complementary medicine for hepatitis C.
Silymarin, also known as milk thistle, is an herb commonly suggested to help cure hepatitis C liver disease. But a rigorous did not find any beneficial effects from this supplement.

But Even If You’ve Been Cured It Can Have Lifelong Health Implications
“Hepatitis C is a lot more than just a liver disease,” Reau says. “It has been associated with many medical conditions, such as an increased risk of developing diabetes, kidney disease and cancer.”
While curing hepatitis C significantly reduces the risk of serious complications, like liver failure, liver cancer and the need for transplantation, it doesn’t completely eliminate the health risks associated with the disease.
“Hep C is linked to scarring of the liver or cirrhosis and the more scar tissue that develops, the greater the likelihood of complications,” Reau says. “If there is a lot of scarring, you will need lifelong monitoring.”
Reau also recommends leading a healthy lifestyle to help prevent re-infection and further liver damage: Limit alcohol consumption, control your weight, avoid high-risk activities and manage diabetes if you have it.
How Do You Get Hepatitis A
Hepatitis A can be spread by sexual contact with an infected person or close personal contact . However, it is most often spread by what scientists call the fecal-oral route. This happens when one person eats or drinks something that has small amounts of fecal matter from another person who has hepatitis A. This can happen by touching something that has the virus on it and then putting your hands in your mouth. It can happen when food is grown, picked, processed or served. Water can also be contaminated.
Mothers do not pass on hepatitis A in breast milk. You cannot be infected with HAV by sitting near to or hugging someone with hepatitis A. It does not spread through coughs or sneezes.

Is There A Way To Prevent Hepatitis C
Although currently theres no vaccine to protect people from contracting hepatitis C, there are vaccines for other hepatitis viruses, including hepatitis A and hepatitis B.
If you receive a hepatitis C diagnosis, your healthcare provider may advise you to get vaccinated against hepatitis A and B.
The vaccinations are recommended because these hepatitis viruses can lead to additional health and liver complications, especially in those with preexisting liver disease.
Since you cant prevent hepatitis C through a vaccine, the best prevention is to avoid exposure. Hepatitis C is a bloodborne pathogen, so you can limit your chances of exposure through these healthy lifestyle practices:
- Avoid sharing needles, razor blades, or nail clippers.
- Use proper safety precautions if youll be exposed to bodily fluids, such as when performing first aid.
- Hepatitis C isnt usually transmitted through sexual contact, but its possible. Limit your exposure by practicing sex with a condom or other barrier method. Its also important to openly communicate with sexual partners and to get tested if you suspect youve been exposed to the hepatitis C virus.
Because hepatitis C is transmitted through blood, its possible to contract it through a blood transfusion.
However, since the early 1990s, blood product screening tests have been standard protocol for minimizing the risk of this type of transmission.
Subsequent testing is based on risk. Talk to your doctor about your needs.
How Is Hepatitis A Diagnosed
The health care professional will ask questions about the illness and symptoms, and about any possible exposures to other people diagnosed with hepatitis, especially the type of hepatitis .
If the health care professional determines that the patient may be at risk for contracting hepatitis, then it is likely the patient will undergo blood tests.
- The blood will be tested to determine how well the liver is functioning.
- A test will be ordered to detect antibody to hepatitis A. The results of this test will also determine if the patient has been recently exposed to HAV.
- Blood probably will be tested for the hepatitis B and hepatitis C viruses, and others. For example, if a patient has had a large amount of vomiting or has not been able to take in liquids, the blood electrolytes may be out of balance. Blood chemistry may be tested to check electrolytes.

There are no specific medicines to cure infection with hepatitis A. Most people require no treatment except to relieve symptoms. However, if symptoms become severe or dehydration develops, the person should seek medical care emergently.
There is a vaccine for hepatitis A . If you have been exposed to someone who is infected with HAV, a treatment called immune serum globulin is available and may prevent you from becoming infected. Immune serum globulin is more likely to be effective when given within 2 weeks of exposure.
