Probably both.
"Warmer weather" [I]might[/I] only slow it down a bit but not necessarily stop it in its tracks. (Think Singapore.)
Whichever way the wind blows.
Airport staff running around with "temperature sensors" is OK, but has its own limitations.
Someone [I]has[/I] a fever, (maybe from a common cold). "Alert".
Someone [I]with[/I] COV-19 but [I]no[/I] symptoms yet isn't detected. "No Alert".
Doesn't quite make sense for me.
But better than nothing, I guess.
