Supplement

Traveler's diarrhea is a form of gastroenteritis. Gastroenteritis is an acute inflammation of the stomach and the intestines due to an infection with a pathogen. It is characterized by anorexia, diarrhea, vomiting, and abdominal pain. The most common causative agent is the toxigenic Escherichia coli. Other bacterial pathogens are Campylobacter, Shigella, 'Staphylococcus aureus, Salmonella, Vibrio parahaemolyticus, Rotavirus, Giardia, and amoebae. Traveler's diarrhea is contracted through travel to developing countries, particularly where there is poor hygiene and sanitation. Travelers mainly from the developed world are often affected (hence, the name). These travelers are the ones at risk rather than the local residents since the latter are exposed constantly or repeatedly to these pathogens that they eventually develop immunity against the pathogens.

The common route is the ingestion of contaminated objects, food, and water. Thus, prevention is essential and can be done by observing proper hygiene and sanitation, proper cleaning and cooking of food, drinking bottled water, etc.
