What are health risks if living in a developing country in se asia?

Some, but GO visit!: The field of travel medicine is dedicated to encouraging travelers, but educating, immunizing, and preparing them to have a safe and healthy trip. Risks depend on specific location, activities, and travel duration. Think food/water concerns, perhaps malaria, other infections (dengue, typhoid), and less obvious things like trauma (rent a helmet with your bike), and std's. But all preventable!
