Health Problems among short-term travelers from developed countries to Southeast Asia: A Prospective Study.


Background of the research:


         Southeast Asia is one of the most visited destination among travelers from developed countries. The incidence of health problems among travelers to this region is still unknown. Because most of the data were from ill returned travelers who seek for medical care, or focused on some specific diseases. Only few cohort studies had been done, with very small proportion of travelers visiting Southeast Asia.

         Therefore, this study will be conducted, follow the same cohort since they begin their travel to the end of the travel in order to determine the chance of getting sick while travel and also after return to their countries of residence. Not only that, but also how they manage with their health problems and how these problems impact on them.
