Traveler's diarrhea or traveller's diarrhoea, abbreviated to TD, is the most common illness affecting travelers^[1]. Traveler's diarrhea is defined as three or more unformed stools in 24 hours passed by a traveler, commonly accompanied by abdominal cramps, nausea, and bloating.^[2] It does not imply a specific organism, but enterotoxigenic Escherichia coli is the most common.^[3]

Most cases are self-limited and the pathogen is most often not identified.
