The term Traveller's Diarrhea is used to describe gastrointestinal infections affecting travellers caused by ingesting bacteria, viruses, and protozoa. These microorganisms are found worldwide and are typically transmitted from person to person via the fecal-oral route – an infected person who does not practice proper hand or body hygiene passes on the infection to another person when handling food and water. Traveller's Diarrhea is one of the most common illness among travellers.
Traveller’s Diarrhea can happen when:
The golden rule to prevent gastrointestinal infections is: Boil it, Cook it, Peel it, or Forget it! However, it’s not just about what you eat, it’s also important to consider where you eat. It’s not always easy to know if a restaurant or food vendor follows proper food handling and hygienic practices (separating raw from cooked ingredients, properly cleaning cutting boards, utensils, sink to wash hands, refrigeration). Be cautious of food that has been stored uncovered, has been improperly refrigerated, or has been standing out for a long time such as buffets.
Consult your doctor for the best diarrhea treatment options tailored to your needs. Travellers who have pre-existing health conditions and are more susceptible to gastrointestinal infections may consider taking preventive medication.
