Kind of like the temp testers, at the airports.
Hope they are actually TESTERS and SCREENERS, versus SPREADERS. 🦠
If the temp monitor touches the foreheads, they are spreaders.
Maybe even if the ‘testee’ breathes on it.
We have no clue how to really shut down viral transmission wrt movement.
Clearly ‘no travel’ for a cpl incubation periods is the only real answer.
