    Traveler’s diarrhea is diagnosed primarily based on clinical symptoms and travel history. A diagnosis requires at least 3 unformed stools in 24 hours, plus at least one of the following: abdominal cramps, fecal urgency, fever, nausea, or vomiting.[1][2] To be considered traveler’s diarrhea, the condition must occur while traveling or within 10 days of returning home.[1] In severe or unresolved cases, stool samples may be taken to identify the causative pathogen.[1]
