What this Trial Is About
Researchers are studying the frequency and causes of travelers' diarrhea among Australian adult tourists visiting Southeast Asia countries such as Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Thailand, Timor-Leste, and Vietnam. This observational study aims to gather information that will help design future clinical trials focused on preventing or treating travelers' diarrhea in this group. The study will observe 1200 healthy adult Australian tourists planning to travel to Southeast Asia for 14 to 28 days. Participants will be monitored during their travels, and diagnostic tests, including the TAQMan Array Card real-time PCR test, will be used to identify diarrheal pathogens when symptoms occur. Participants will be involved for about 28 days post-travel and must have access to a smartphone and mobile phone service while traveling. Researchers will collect data on diarrhea episodes, including their frequency and causes, over an 18-month period. The study includes follow-up activities to ensure comprehensive data collection and safety monitoring throughout the travel and post-travel period.
