Moreover, in Thailand, the health services are developed at a high level and you will always have expert medical help in case of need.

The most common among tourists are intestinal infections and diarrhea. And in 98% of cases it occurs because of failure to comply with the above rules of hygiene, and only 2% because of the poor quality of local water and food.
