Hepatitis A is a virus that can cause mild to severe symptoms, including fever and digestive issues. It
can cause complications such as liver failure. It is usually contracted via contaminated food or water and can also be passed on from person to person contact. It can be common in many foreign countries where sanitation and access to safe food and water is poor.
If you are travelling abroad, you can visit the UK NHS website Fitfortravel or the National Travel Health Network and Centre to find out if immunisation against hepatitis A is recommended. If you are at high risk, the most effective way is to protect yourself via the vaccine alongside practising good hygiene and lifestyle precautions.
