Hepatitis A is a viral infection that causes inflammation of the liver. It can begin with tiredness, fever or loss of appetite before more recognisable symptoms, such as yellowing of the eyes, appear. Some people have a mild illness, while others feel unwell for several weeks.
Most people recover fully, and hepatitis A does not become a long-term infection. However, it can occasionally cause serious illness, so recognising symptoms and protecting close contacts are important parts of care.
How does hepatitis A spread?
The hepatitis A virus leaves an infected person’s body in their stool. Infection occurs when tiny amounts of the virus reach another person’s mouth, usually through contaminated food, water or hands. This is called the faecal–oral route.
For example, someone who has the infection may contaminate food if they prepare it without washing their hands properly after using the toilet. Water contaminated by sewage can also spread the virus. Close contact involving exposure to infected stool, including certain sexual activities, is another route.
Hepatitis A does not spread through ordinary coughing, sneezing or simply sitting beside someone. Understanding the route of infection helps families focus on useful precautions without treating the person who is unwell as someone to fear or blame.
What symptoms should you look for?
Symptoms usually develop around two to seven weeks after exposure. Early signs can include fever, tiredness, poor appetite, nausea, vomiting and abdominal discomfort. Some people also experience diarrhoea or joint pain, which can initially make the illness seem like another common infection.
Urine may become unusually dark, stools may become pale, and the whites of the eyes or skin may turn yellow. This yellowing is called jaundice. Not everyone develops every symptom, and the absence of jaundice does not rule out hepatitis A.
Young children often have few symptoms or none at all, while adults are more likely to feel noticeably unwell. A child who appears well can still have the infection and pass it to others, which is why symptoms alone cannot determine whether household contacts need advice.
When does it need urgent medical attention?
New yellowing of the eyes or skin needs prompt medical assessment. Go to an emergency department if someone with suspected hepatitis develops confusion, unusual behaviour, marked drowsiness or difficulty staying awake. Significant bleeding or severe abdominal pain also requires urgent attention. These can be signs of a serious complication rather than ordinary tiredness during recovery.
Repeated vomiting can make it difficult to replace lost fluids. Seek urgent help if the person cannot keep fluids down, passes very little urine or becomes persistently dizzy when standing. Children and older adults are particularly vulnerable to dehydration.
People who are pregnant, older adults and anyone with an existing liver condition should contact a doctor promptly if hepatitis A is suspected. The doctor can decide whether closer monitoring or hospital assessment is needed.
How do doctors confirm the diagnosis?
Your doctor will ask about symptoms, recent travel, food and water exposures, and whether anyone around you has been diagnosed with hepatitis A. An examination and blood tests help establish what is happening. Symptoms alone cannot reliably distinguish hepatitis A from other forms of viral hepatitis.
A blood test called IgM anti-HAV helps identify a current or recent hepatitis A infection. The result needs to be interpreted alongside your symptoms and history because, in some circumstances, a positive result can have another explanation.
A different antibody, called IgG anti-HAV, generally indicates protection from a previous infection or vaccination. It does not, by itself, mean that you currently have hepatitis A. This distinction is useful when a report simply appears to say that a hepatitis A antibody is “positive.”
Your doctor may also check liver blood tests, including ALT and bilirubin. These provide information about the effect on the liver, but they do not replace the specific testing needed to identify the virus.
What treatment is available?
There is no specific antiviral treatment routinely used to cure hepatitis A. Care usually focuses on rest, adequate fluids and balanced nutrition while the body clears the infection. Some people need hospital care because their illness is severe or they cannot manage safely at home.
Your doctor may prescribe medicines to ease symptoms such as nausea or itching. Follow the prescribed instructions and attend any recommended blood tests or follow-up appointments. Feeling better is encouraging, but your doctor may still need to check how the liver is recovering.
A practical home plan should make it clear what you can eat and drink, which medicines are suitable, and which changes require another assessment. Before leaving the appointment, ask whom to contact if vomiting increases, drinking becomes difficult or a new symptom develops.
Eating and drinking during recovery
The general aim is to maintain nourishment and hydration. A balanced diet can include familiar foods rather than an expensive or complicated recovery menu. Choose meals you can tolerate and tell your doctor if poor appetite is making it difficult to eat enough.
Families can help by preparing food, offering drinks regularly and allowing time to rest. If another condition affects your usual diet or fluid intake, ask how to adapt the recovery advice to that condition. The plan should be manageable for the person who is unwell, rather than based on pressure to eat or drink a particular item.
If nausea makes drinking difficult, small, frequent sips may be easier than a large glass at once. Continue watching for reduced urine, dry mouth or dizziness, and seek help if fluids are not staying down.
Be careful with medicines and supplements
Tell your doctor about everything you take, including regular prescriptions, painkillers, vitamins, herbal products and products sold as liver tonics. Some medicines and supplements can harm an inflamed liver or need a different approach during the illness.
Do not start a new product because it is described as natural or recommended by someone who previously had jaundice. Check with your doctor before taking it, and ask for advice before changing any regular prescription medicine. Avoid alcohol until your doctor confirms that you have recovered.
What should family members do after exposure?
Contact a doctor promptly if someone in the household has hepatitis A, even if everyone else feels well. Vaccination given within two weeks of exposure can help prevent illness. Depending on the exposed person’s age, health and vaccination history, the doctor may also recommend immune globulin, which provides temporary protection.
Do not wait for jaundice or fever before asking about protection. Explain when the diagnosis was made, when close contact occurred and whether previous hepatitis A vaccinations are documented. The doctor can determine who needs preventive treatment and how quickly it should be arranged.
Someone with hepatitis A can spread the virus before symptoms begin. This means exposure may already have happened before the family realised that anyone was ill. Prompt advice is more useful than trying to identify exactly which meal or interaction caused the infection.
How can you reduce spread at home?
Wash hands thoroughly with soap and water after using the toilet, after changing nappies or helping someone with toileting, and before preparing or eating food. Help children with these steps rather than assuming they can manage them consistently on their own.
The person who is infected should avoid preparing food or drinks for others while infectious. Ask the doctor when it is appropriate to return to school, childcare or work, especially if the work involves handling food. Feeling well enough to resume normal activities does not automatically establish that the infectious period has ended.
What about food and water outside the home?
Safe food and water remain important, particularly when travelling or when sanitation is uncertain. Contamination can happen during growing, processing, preparation or serving, so the appearance of a restaurant or food item cannot provide complete reassurance.
Choose reliably safe drinking water and food that has been properly cooked and handled. Be cautious about ice when its water source is uncertain: freezing does not reliably destroy the hepatitis A virus. These precautions complement vaccination rather than replacing it.
If travel is planned, discuss hepatitis A protection before departure. Take your vaccination record to the appointment so the doctor can assess what protection you already have and whether anything further is needed.
Can vaccination prevent hepatitis A?
Vaccination offers effective protection against hepatitis A. In India, the Indian Academy of Pediatrics includes hepatitis A vaccination in its recommended childhood schedule, beginning at around 12 months. The number of doses depends on the vaccine used.
An inactivated hepatitis A vaccine requires a two-dose course, while the recommended live attenuated vaccine uses a single-dose schedule. Ask your child’s doctor which vaccine was given and whether the course is complete. A record of the vaccine name and date is more useful than remembering only that a “hepatitis injection” was received.
Adults can also discuss vaccination with their doctor, particularly before travel or if they have chronic liver disease. Previous vaccination, past infection and current health all matter when deciding what protection is needed. Advice after a recent exposure is more urgent than a routine vaccination discussion.
How long does recovery take?
Most people’s symptoms settle within about two months, although some remain unwell for several months. Recovery can feel uneven, and a minority experience symptoms returning after initial improvement. Report renewed symptoms to your doctor rather than assuming that every setback is harmless.
Most people recover without lasting liver damage. Serious illness is uncommon but is more likely in older adults and people with underlying liver disease, which makes individual follow-up important. Give your doctor a clear account of changes in appetite, energy, vomiting and daily functioning.
After recovery, a confirmed hepatitis A infection generally provides lifelong protection against hepatitis A. It does not protect against other hepatitis viruses, so future symptoms or other vaccination needs still require their own assessment.
