That implied that people would still be negative because of the incubation period, but I am willing to write it off as poor English.

Regardless, no-one knows how long it takes for a test to pick up infection.

Also, even during the closure of the borders, an estimated 15,000 people are arriving into the country daily. How this will be policed when we have even more people arriving will be challenging.
