Hepatitis A risk factors: what to know

Hepatitis A is an infection of the liver that can spread when very small amounts of infected stool reach the mouth. This may happen through unsafe water, food handled without careful handwashing, or household and sexual contact with someone who has the infection. People who work in settings involving childcare, food preparation, sanitation, or healthcare may need tailored advice. Travel plans, living with someone recently diagnosed, and some liver conditions can also affect whether vaccination or testing should be discussed. Risk depends on the situation; having a risk factor does not prove that you have hepatitis A.

Wash hands with soap and water after using the toilet, changing nappies, and before preparing or eating food. Take care with drinking water and food hygiene when travelling, and ask a clinician about Hepatitis A Vaccination before travel or after a known exposure. If illness is suspected, avoid preparing food for other people and arrange medical advice. A clinician may consider a Liver Function Test alongside other checks when symptoms or exposure history point toward liver inflammation.

Contact a clinician promptly after close contact with a confirmed case, especially if you are pregnant, have liver disease, or have a weakened immune system. Seek urgent care for severe vomiting, confusion, unusual sleepiness, bleeding, or rapidly worsening yellowing of the skin or eyes. Earlier symptoms can include Nausea, Loss of Appetite, Feeling Generally Unwell, or Dark Urine; these symptoms have many possible causes, so they do not by themselves establish hepatitis A.

Ask whether your exposure calls for vaccination, testing, temporary food-handling precautions, or follow-up. Bring the date and type of contact, recent travel details, your vaccination record, and a list of medicines or supplements.
