Protect Yourself with the Hepatitis A Vaccine Before Your Next Trip

Travelling abroad? Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus (HAV). It spreads through contaminated food, water, or contact with infected individuals, making it a common concern for travellers visiting regions with poor sanitation like Africa and India. Don’t take risks — ensure you are protected with a hepatitis A vaccine before travelling.

 

What is Hepatitis A? Understanding the Infection

Hepatitis A, also known as Hep A disease, is a viral infection that inflames the liver, causing symptoms such as fatigue, nausea, stomach pain, and jaundice. The hepatitis A infection symptoms can vary from mild to severe and typically appear 2 to 6 weeks after exposure. Although the disease doesn’t usually cause long-term liver damage, it can be dangerous for individuals with pre-existing liver conditions.

Signs and Symptoms of Hepatitis A Infection

Hepatitis A is a viral infection that primarily affects the liver, causing a range of symptoms that can develop within 2 to 6 weeks after exposure. These symptoms vary in severity, with some individuals experiencing mild discomfort while others endure more intense signs. Understanding these symptoms early can help reduce the risk of complications and prevent the spread of the hep A virus.

 

Fatigue and Weakness

Fatigue and a persistent feeling of weakness are common early indicators of hepatitis A disease. As the liver struggles to perform essential functions, such as detoxifying the blood and producing energy, patients often feel drained and may find it hard to carry out daily activities. This exhaustion can linger for weeks, even after other symptoms subside.

Nausea, Vomiting, and Loss of Appetite

The hep A infection disrupts digestion, leading to nausea, vomiting, and a decreased appetite. Many individuals find it difficult to eat, resulting in unintended weight loss and dehydration. This symptom is particularly problematic if vomiting becomes persistent, as it may require medical attention to prevent further complications.

Abdominal Pain and Diarrhoea

Patients with hepatitis A often report upper-right abdominal pain, where the liver is located. This discomfort can be accompanied by cramps and diarrhoea, as the infection affects bile production—critical for digesting fats. These gastrointestinal issues are often early signs that indicate liver stress, particularly in children who are more likely to experience mild symptoms that mimic a stomach bug. 

Dark Urine and Pale Stools

One of the more noticeable signs of hep A virus infection is dark urine and pale or clay-coloured stools. These changes are due to the build-up of bilirubin, a substance usually processed by the liver. When the liver is impaired, bilirubin leaks into the bloodstream and is excreted through urine, making it appear darker. At the same time, reduced bile flow leads to pale stools. 

 

Yellowing of the Skin and Eyes (Jaundice)

Jaundice, the yellowing of the skin and whites of the eyes, is a key indicator of hepatitis A infection. It occurs when bilirubin builds up in the bloodstream due to the liver’s inability to process it effectively. Although not everyone with hepatitis A develops jaundice, it is more prevalent in adults than in children. Patients may also experience itchiness due to the accumulation of bile salts in the skin. 

When to Seek Medical Advice

If you experience any of the above symptoms—especially if you have travelled to a high-risk area or consumed contaminated food—it is essential to seek medical advice promptly. A blood test can confirm the presence of the hep A virus, and healthcare professionals can provide guidance on managing symptoms and preventing further spread of the infection. 

Preventing the Spread of Hepatitis A

Hepatitis A is highly contagious and spreads through direct contact with infected individuals or through contaminated food and water. If diagnosed, patients should practise good hygiene, such as regular handwashing, and avoid preparing food for others to limit transmission. Vaccination remains the most effective way to prevent infection, particularly for travellers and individuals at high risk of exposure.

Recognising these hepatitis A symptoms early can aid in timely treatment and prevent the disease from spreading further.

Why Get the Hepatitis A Vaccine?

Vaccination is the best way to protect against hepatitis A infection. The hepatitis A immunisation helps your body build immunity, preventing illness if you come into contact with the virus. The hepatitis A vaccine is available in two forms:

• Single-antigen hepatitis A injection (e.g., Havrix or Vaqta) – Two doses six months apart
• Combination hep A shot (Twinrix) – Three doses over six months, protecting against both hepatitis A and B

Even if you can’t complete the full series before travel, receiving at least one hep A shot offers partial protection. 

 

Who Should Get the Hepatitis A Vaccine?

Certain groups are at higher risk of contracting hepatitis A disease and should prioritise vaccination including:

• Travellers to areas with high rates of hepatitis A infection
• Individuals with chronic liver disease or compromised immune systems
• Childcare and healthcare workers in contact with vulnerable populations
• Plumbers, engineers, water and wastewater operators
• Close contacts of infected individuals

If you are travelling on short notice, ask about accelerated vaccination schedules to ensure you’re covered in time.
