People on lanta say that immigration is coming there soon to solve this problem. I also hope we may get an announcement tomorrow regarding issues like this. Good luck.
Well our experience at Makro was our small daughter was just over the temperature. Provably because she came out of air con onto the hot motorbike. She had to sit and wait for a few minutes until her temp dropped.
This is going to be a big issue soon and people will have to be allowed to stay. Thailand might end up a bit of an expat refuge from corona if things somehow stay under control here.
