Overview
The most potent risk factor in the development of traveler's diarrhea is history of recent travel to a developing country in the past 4 months (required for the diagnosis of traveler's diarrhea). Other risk (in addition to recent travel) include immunocompromised status, pregnancy, recent ingestion of uncooked or poorly handled vegetables, meat (e.g. hamburgers), poultry, raw milk, or poorly stored foods that require refrigeration (e.g. mayonnaise), drinking from untreated water, exposure to infected individuals, daycare, and healthcare settings, intake of H2-blockers, and recent sexual history of receptive anal or oral-anal contact.
