Bangkok hospital in Ratchaburi not very many of the doctors speak english fluently. Not even close to fluent. But this Bangkok hospital is cheaper than ones in other areas. I think when my wife had surgery there an ICU room was 12,000 baht per day. A far cry from what they are quoting in the article. My wife had a titanium plate put in her neck and the total bill was cheaper than what they are saying for about 2 days for him.
What is confusing about the story, as someone else already mentioned, if a mosquito bit him on a ride in a taxi to the airport he would have been out of the country before he turned ill. And what's up with them saying 'rare mosquito bite'. It's quite a common occurrence.
