I also don't see how the system would work at scale. In
example (1),<br class="">
rooms 1 and 2 are marked as contaminated simply because

The rooms are marked contaminated as a result of a test, in the

Another one I forgot: what about asymptomatic
transmission, which seems quite big on this virus? (I
think recent estimates in the US give 5-20 unknown
infected for every known case; forgot the reference,
sorry). I don't see how the tact systems can help with
that; those people might never know they are carriers.<br class="">
