Travellers' diarrhoea is a frequent problem for travellers. Access to a safe water supply when travelling, is undoubtedly a paramount issue. Water and food precautions are important for travellers to be aware of and followed, as is attention to general hygiene. In some situations, chemoprophylaxis and standby treatment with antibiotics may be needed. It is essential that travellers, especially those travelling with young children, be familiar with the use of oral rehydration solutions and the prevention of dehydration.
