    Travellers’ diarrhoea is one of the most common illnesses in people who travel internationally, and depending on destination affects 20-60% of the more than 800 million travellers each year. In most cases the diarrhoea occurs in people who travel to areas with poor food and water hygiene.1 This review examines the approach to the prevention and treatment of diarrhoea in travellers.

The use of antibiotics for self treatment or chemoprophylaxis, however, remains debatable.

    Sources and selection criteria

Additional studies were sourced from the retrieved articles. We also reviewed our extensive collection of articles on the subject, as well as current national guidelines in travel medicine.

    • Evaluation and management of returned travellers with diarrhoea includes maintaining hydration during mild illness, bacterial culture of stools and empirical treatment during moderate to severe illness, and, in protracted cases, examination of stools for ova …
