Someone else said they will use IR thermometers, but I don’t know how close to the target they have to be to get an accurate reading....
The ones I’ve used, you had to be within a few inches.
(Granted, those were food-service thermometers. I have no idea if medical IR thermometers are different.)
The one’s I’ve had used on me had actual contact with my skin, if I remember correctly. Therefore, my idea of incinerating each thermometer that registers a fever in Ebola country.
