The study proposed here will determine the frequency and etiology of diarrhea in Australian adult tourists traveling to Southeast Asia, including Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Thailand, Timor-Leste, and Vietnam. The results from this study will inform the feasibility and design of subsequent clinical trials of travelers' diarrhea interventions in this population.
