We have become well used to having out temperature checked by means of an infrared thermometer.
Airports are deciding whether people can enter workplaces, or even fly
accross the globe, on the basis of the readings of these thermometers.
Of course most of these are based on a standard chinese model and
arrive with no calibration, and with most cases insufficient
documentation to allow vertified calibration.
We did a few tests and found errors of over 1.5C; which is clearly useless for checking fever.
A cycnical co-worker noted that the Chinese now control who works and
who doesn't, who flies and who gets quarantined.....and you can be
sure that these devices have built in face recognition connected by
You most likely confuse "a few inches away" thermometer with infrared
camera measuring human temperature.
Airport can get a few "higher class" infrared thermometer and conduct
temperature measure e.g. during security checks, can't they? It won't
_stop_ Covid-19. It will be one more step to _reduce_ infection rate.
Anyway it is "not a bad idea" even after Covid-19 pandemic. It should
help to reduce yearly influenza infections and may at least slow next
SARS/MERS/Covid-19 with policy "measure temperature always, (slightly)
lower no-pass temperature during epidemic".
Have you considered "bio-terrorists" using Covid-19?
Asymptomatic carriers are not too hard to find even if Covid-19
"lacks in deadliness".
