Going on holiday from an airport with mild temperature, can airport security detect this and think it is Coronavirus?

I am going on holiday very soon and I have a mild temperature, I feel quite well and in my honest opinion, I am fit to travel. I will take my medication with me etc. I also look quite well.

I have a worry though. Can airport metal detectors/x-rays in the UK or in any airport detect temperature? If so and they want to pull me over for a check I will allow more time for airport security.

Also, do you think they might have to test/quarantine me for coronavirus as the symptoms according to the NHS are:

• a cough
• a high temperature
• shortness of breath

I have a medium temperature and a mild cough (2 of 3 symptoms). It would be a pain and really upsetting to ruin my holiday.
