Hepatitis A symptoms
Introduction
Hepatitis A is a liver infection caused by the hepatitis A virus. It spreads mainly through contaminated food or water and close contact with an infected person. Understanding Hepatitis A symptoms helps Canadians recognise the illness early and seek proper care.
The infection often starts suddenly and can range from mild to severe. Many people recover fully without lasting liver damage. However, knowing the signs and how the virus spreads is important to prevent outbreaks and protect public health.
Hepatitis A is a vaccine-preventable disease, and awareness of its symptoms plays a crucial role in early detection and timely intervention. Prompt recognition can reduce transmission and improve patient outcomes.

Key facts
- Hepatitis A symptoms usually appear 2 to 6 weeks after exposure to the virus.
- Common symptoms include fatigue, nausea, abdominal pain, loss of appetite, and low-grade fever.
- Jaundice, or yellowing of the skin and eyes, often develops as the infection progresses.
- Most people recover fully within a few weeks to months without lasting liver damage.
- The virus spreads primarily through contaminated food or water and close personal contact.
- Good hygiene and vaccination are effective ways to prevent hepatitis A infection.
- Symptoms tend to be milder in children but can be more severe in adults and older adults.
- Hepatitis A does not cause chronic liver disease, unlike hepatitis B and C.
Symptoms
Hepatitis A symptoms usually appear two to six weeks after exposure to the virus. They can range from mild to severe and often last less than two months. Some people, especially young children, may show no symptoms at all, making it possible to unknowingly spread the virus.
Common Symptoms
- Fatigue and weakness
- Loss of appetite
- Nausea and vomiting
- Abdominal pain, especially near the liver
- Dark urine and pale stools
- Jaundice (yellowing of the skin and eyes)
- Fever and muscle aches
These symptoms often develop gradually and can mimic other illnesses such as the flu or gastrointestinal infections, which sometimes delays diagnosis.
Less Common Symptoms
Some people may experience joint pain, itching, or diarrhoea. These symptoms are less frequent but can still affect daily activities and quality of life. Itching, or pruritus, is thought to result from bile salt accumulation due to liver dysfunction.
Severity and Red Flags
Most cases resolve without complications. However, severe symptoms such as persistent vomiting, confusion, severe abdominal pain, or signs of liver failure require immediate medical attention. These red flags indicate a need for urgent care and possible hospitalisation.
Recognizing Hepatitis A symptoms early helps prevent spreading the infection and ensures timely treatment. In rare cases, fulminant hepatitis A can occur, leading to acute liver failure, which is life-threatening and requires specialised care.
Causes and risk factors
Hepatitis A symptoms result from infection with the hepatitis A virus (HAV). This virus spreads primarily through the fecal-oral route, often by consuming contaminated food or water. Close contact with an infected person also increases the risk of transmission, especially in households or among sexual partners.
Age and sex
Children under the age of 6 often experience mild or no symptoms, while adults tend to have more noticeable symptoms. Both males and females are equally susceptible to infection, but severity may vary with age. Older adults are at higher risk of severe disease and complications.
Comorbidities
People with chronic liver disease or weakened immune systems face a higher risk of severe illness from hepatitis A. Pre-existing conditions such as hepatitis B or C infection, cirrhosis, or immunosuppressive therapy can worsen the impact of the infection and prolong recovery.
Lifestyle factors
- Travel to areas with poor sanitation increases exposure risk.
- Living in crowded or unsanitary conditions facilitates virus spread.
- Consumption of raw or undercooked shellfish can lead to infection.
- Close contact with someone infected, such as household members or sexual partners, raises the chance of transmission.
- Working in childcare or healthcare settings may increase exposure risk.
Understanding these causes and risk factors helps in preventing hepatitis A symptoms and controlling outbreaks effectively. Public health measures targeting these risk factors are essential in reducing disease incidence.
Diagnosis
Diagnosing hepatitis A symptoms begins with a thorough clinical evaluation. Your healthcare provider will review your medical history and ask about recent activities that might increase your risk of infection, such as travel or exposure to contaminated food or water.
History and Physical Exam
The doctor will inquire about symptoms such as fatigue, nausea, and jaundice. A physical exam will check for signs like tenderness in the abdomen or yellowing of the skin and eyes. The provider may also assess for enlarged liver or spleen.
Common Tests
To confirm the diagnosis, blood tests are usually ordered. These tests detect antibodies specific to the hepatitis A virus, indicating a recent or past infection.
- Anti-HAV IgM test: identifies recent infection and is the primary diagnostic tool.
- Liver function tests: assess liver damage by measuring enzymes such as ALT and AST.
- Complete blood count: checks overall health and detects any associated abnormalities.
Patients can expect a straightforward process. The blood sample is typically drawn from a vein in the arm. Results often return within a few days, allowing timely management of the condition. In some cases, additional tests may be performed to rule out other causes of hepatitis.
Treatment and management
Treatment for Hepatitis A symptoms mainly focuses on supportive care. Since the infection usually resolves on its own, medical interventions aim to ease discomfort and prevent complications.
Conservative and medical treatments
Most patients recover without specific antiviral drugs. Doctors recommend rest and adequate hydration to help the body heal. Over-the-counter pain relievers such as acetaminophen can reduce fever and muscle aches, but aspirin should be avoided to prevent bleeding risks, especially in children and adolescents.
Lifestyle measures
Adopting healthy habits supports recovery and limits virus spread. Key lifestyle measures include:
- Eating a balanced diet rich in fruits and vegetables to support liver health.
- Avoiding alcohol and substances that strain the liver during recovery.
- Practising good hand hygiene, especially after using the washroom and before preparing food.
- Staying home from work or school until symptoms improve to prevent transmission.
- Getting plenty of rest to aid the immune system in fighting the infection.
Follow-up
Regular follow-up with a healthcare provider ensures symptoms improve and liver function returns to normal. Blood tests may be repeated to monitor recovery. Most people fully recover within a few weeks to months without lasting liver damage. In rare cases of severe hepatitis, closer monitoring or hospitalisation may be necessary.
Prevention and self-care
Preventing hepatitis A symptoms starts with good hygiene and safe practices. The virus spreads mainly through contaminated food or water and close contact with an infected person. Taking simple steps can reduce your risk significantly.
Practical prevention tips
- Wash your hands thoroughly with soap and water before eating and after using the bathroom.
- Drink bottled or boiled water when travelling to areas with poor sanitation.
- Avoid raw or undercooked shellfish and other high-risk foods.
- Get vaccinated if you are at higher risk or planning to travel to endemic regions.
- Clean and disinfect surfaces regularly, especially in shared spaces and kitchens.
- Practice safe sex and avoid sharing personal items like towels or toothbrushes.
Self-care strategies
If you experience hepatitis A symptoms, rest is essential. Stay hydrated by drinking plenty of fluids such as water, oral rehydration solutions, or clear broths. Avoid alcohol and fatty foods, as they can strain your liver. Follow your healthcare provider’s advice and attend all follow-up appointments.
Do not share personal items like towels, toothbrushes, or eating utensils. This helps prevent spreading the virus to others. Practising these dos and don’ts supports your recovery and protects those around you.
When to seek medical help
Recognizing when to get medical help for Hepatitis A symptoms is important. Some signs need urgent care, while others can be managed with routine visits. Knowing the difference helps you get the right treatment quickly.
Urgent care
Seek immediate medical attention if you experience any of the following:
- Severe abdominal pain
- Persistent vomiting or inability to keep fluids down
- Yellowing of the skin or eyes (jaundice) that worsens rapidly
- Confusion, drowsiness, or difficulty waking up
- Dark urine or pale stools
- Signs of bleeding such as easy bruising or bleeding gums
These symptoms may indicate serious liver problems and require prompt evaluation and possible hospitalisation.
Routine care
If you notice mild Hepatitis A symptoms such as fatigue, mild nausea, or low-grade fever, schedule a routine appointment with your healthcare provider. They can confirm the diagnosis and advise on managing symptoms at home.
Routine care is also important for follow-up to monitor recovery and prevent complications. Your provider may recommend lifestyle adjustments and provide information on preventing transmission to others.
