That will undoubtedly be the case but cheap and simple testing may change the game.
As I understand it, the incubation period is the time from exposure to becoming symptomatic. From my childhood it would be the time between the birthday party where an asymptomatic kid was hatching Chicken Pox and the appearance of my first spot.
The incubation for Covid leads to the cough, loss of taste and so on as symptoms after 7+ days.
An immune reaction may be present well before symptoms. If there's no immune response, as verified by a test, at the point one would be expected then the subject is not infected.
