Traveller's diarrhoea.

BACKGROUND

There has been little if any change in the incidence of traveller's diarrhoea over the past 20 years.

OBJECTIVE

This article aims to provide a basic understanding on why travellers are more likely to experience diarrhoea during travel.

DISCUSSION

In a 20 minute pretravel consultation time is precious, and providing information on traveller's diarrhoea often has a low priority over prescribing the necessary vaccinations and discussing antimalarials. Travellers do not follow the rules of eating and drinking safely, and diarrhoea is common. 'What to do in the event of illness' is an important consideration. Presumptive treatment should be offered to all travellers whose itinerary and activities put them at risk.
