I had a flu last year while in Thailand. I went to Bamrungrad hospital (google it, look at the pictures!) - total payed for visit to the doctor and medications, 1200 baht (35$). That IS cheap, no matter where from are you. People come there from other countries just because service is good and cheap.
Where in Europe would you get doctor and medicine for cheap like that if you didn't have social medical plan? Only a routine examination costs double that amount in most of european countries if you don't have medical insurance.
