On: U.S.-Funded Scientist Among Three Who Fell Ill Amid Early Covid Outbreak

I flew through Hong Kong airport in November 2019 and they had a permanent temperature screening station set up. I even took a photo thinking, how strange is this. Like a massive desk and camera equipment in the middle of the major arrival walkway, it was clearly new

I lived in Macau for 7 years (2009 to 2016) and traveled to Hong Kong frequently from the US. There were always temperature scanners at the airport along with cameras. Travelers had to remove hats when approaching them.

So they were always prepared since SARS

Those things are useless as far as I've read. Feeling of security but walk a bit faster/slower and the results change enough.

Mainland China has had those for as long as I can remember (going back at least as early as 2010).

I’ve seen those in other airports. Pretty sure Narita had them back in early 2019.
