Thermal scanners are quite common in airports, and these are extraordinary times.
If the only people that will be flagged are those with clear symptoms then you don't need a temperature check. Large area thermal scanners that you see in the likes of HKG are managed by the airport, health or border authorities, not by the airlines, that is a huge difference. If somebody is coughing like crazy on an aircraft it could be for any number of reasons and a temperature check isn't going to help.
