Traveller’s diarrhoea is a common condition that affects people visiting regions where food or water safety standards differ from those at home. It occurs when harmful bacteria, viruses, or parasites contaminate food or drinking water, leading to infection in the digestive system. Although usually mild, it can be unpleasant and temporarily disrupt travel plans.

Symptoms typically appear within a few days of arrival and include loose or watery stools, stomach cramps, nausea, bloating, and sometimes fever. In more severe cases, vomiting or dehydration may occur. Most people recover within a few days, but symptoms can last longer if the infection is caused by certain parasites.

The main cause of traveller’s diarrhoea is consuming contaminated food or water. Common sources include raw or undercooked meat, unwashed fruits and vegetables, and drinks made with untreated water. Ice cubes, salads, and street food are frequent culprits in areas where sanitation practices are poor.
