Thai quarantine of 6 countries and territories (South Korea, Italy, China including Hong Kong and Macau, and Iran)

We still have no news from Richard Barrow
But i-Cable just led with the following (on live stream, I can't find the segment in the app)

i-Cable tracked two tourists leaving HKG at 10a and arriving BKK 12p local time
On arrival, health officials identified them as HK arrivals and led them to "Health Counter". Other Caucasian arrivals were also there, presumably because they transited HKG.

They had to fill in health form, and declare their itinerary and contact details. Their temperatures were taken.

They were then advised to self-quarantine for fourteen days. They were told this is not a mandatory order and they can still leave their accommodation or the kingdom before the end of fourteen days.
