Travellers' diarrhoea (TD) is the most common health problem encountered by travellers, effecting 60 to 80 per cent of those travelling to high risk destinations such as Africa, South and South East Asia, South and Central America, and the Middle East. 1,2 Individuals who remain close to locals, engage in low-budget travel, or backpack are at higher risk compared to older travellers on an organised tour or business trip. 1
Travellers' diarrhoea is contracted predominantly through the ingestion of contaminated food or beverages or from person-to-person due to poor hygiene. 1,2
