Research Project:
Incidence of traveler’s diarrhea among adult foreign travelers in Thailand
Background of the research
Diarrhea is the most common health problems reported among travelers during their trips in developing countries. Previous studies showed the reported attack rates was around 30-60%. However, many details informtaion of travelers' diarrhea are remain unknown especially the relation between the travel day and the first event of diarrhea. It is logical to assume that travelers who will eventually develop travelers' diarrhea are likely to experience first episode of diarrhea during the early phase of their trip. However this assumption has never been confirmed before. Therefore, this prospective research will be very important and will help us understand travelers' diarrhea better.
People who may participate in this research are as follows:
1. International travelers with age equal or more than 18 years
2. Arrived Thailand not more than 7 days
3. Can speak English
4. Did not have diarrhea in the first 6 hours after arrival in Thailand
