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.
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.
Side Effects Of Immunisation Against Hepatitis A
Immunisations against hepatitis A are effective and safe. All medications can have side effects.
For most people, the chance of a serious side effect from a vaccine is much lower than the chance of serious harm if you catch the disease.
Common side effects from the hepatitis A vaccine include:
- localised pain, redness and swelling at the injection site
- low-grade temperature

What Are The Signs And Symptoms Of Hepatitis A
- Many people with HAV infection have no symptoms at all.
- Sometimes symptoms are so mild that they go unnoticed.
- Older people are more likely to have symptoms than children.
- People who do not have symptoms can still spread the virus so it is difficult to know when a person has been exposed to the virus.
Symptoms of hepatitis A usually develop between 2-6 weeks after infection. The symptoms are usually not too severe and go away on their own, over time. The most common hepatitis A symptoms are as follows:
- Urine is dark brownish in color, like cola or strong tea.
- Pain in the area of the liver, on the right side of the abdomen just under the rib cage
If the vomiting is severe, dehydration may occur. Dehydration may become serious and life-threatening in some affected individuals, so symptoms of dehydration need to be quickly addressed, often by a medical caregiver. Symptoms of dehydration include the following:
- Feeling weak or tired
- Feeling confused or unable to concentrate
- Rapid heartbeat
- Urinating less frequently than usual
Symptoms of hepatitis A infection usually last less than 2 months, although they may last as long as 9 months. Some people infected with hepatitis A have symptoms that come and go for 6-9 months.
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
Remember that immunisation against hepatitis A does not protect you against hepatitis B or hepatitis C.

Looking After Yourself When You Have Hepatitis A
AlcoholSome people with acute hepatitis develop an aversion to alcohol in the acute phase. Previously people with this condition were told to avoid alcohol for six months following the illness. This advice is no longer thought necessary.
SmokingSmoking is dangerous to everyones health. Smoking can increase the severity of liver damage. People with liver disease are more vulnerable to infection and to poor health overall, so smoking or exposure to passive smoking is not advisable.
DietIf you have a short-term hepatitis infection, for example hepatitis A, you should try to eat a normal diet. However, some people may need extra nutrition to prevent unplanned weight loss, and may benefit from a high-energy and high-protein diet. A dietitian can advise on this.
If you develop nausea and vomiting, our coping with eating difficulties may help. Read more here.

Hurdles And Opportunities In Viral Hepatitis Treatment
In the last decade, rapid and significant advances in diagnosing and managing viral hepatitis were made and changed its treatment. These advances include the development of DAAs for the treatment of chronic hepatitis caused by HCV-with SVR rates greater than 95%, the improvement of HBV vaccination as well as enhancement of the immunogenicity of HBV vaccines, and the identification of antiviral therapies with low rates of viral resistance. Table summarises the current clinical management of viral hepatitis and areas of development for future treatments.

What Are The Symptoms Of Hepatitis A
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.
Medical Treatment For Hepatitis A B & C
Treatment for hepatitis A, B, or C is based on which type of hepatitis is present in the bloodstream and the severity of the resulting liver damage. Depending on the results of diagnostic tests, our specialists at NYU Langone may recommend antiviral medication to stop the virus from replicating and protect your liver from further damage.

Complementary And Alternative Medicines And Therapies
Many complementary and alternative medicines available suggest they can ease the symptoms of liver disease. As with any other medicine, you should use them with care before taking any medicine you should check with your doctor that it is safe to do so.
Most medicines are processed by the liver so they can be toxic to people with liver problems. Some can damage the liver and make you more severely ill. At present, healthcare professionals are not clear on the role and place of some complementary medicines in managing liver disease more research is needed on their use.
Licensing has been introduced for some traditional herbal medicines. However, many herbal products are not classified as a medicine and so can be legally sold as food or cosmetic this means there is no regulation of the product and so you cannot be sure how much of the active ingredient you are getting, or how pure it is. Unregulated products are not monitored or assessed for how effective or safe they are. Some remedies can damage the liver and make you more severely ill. It is wise to be cautious about the claims made about herbal remedies, particularly those advertised on the internet.

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 .
