We would be just as safe without this. I agree with Dr. Douville.
As far as erring on the side of caution goes, my concern would be that if we set up a process that had many advance calls to quarantine officers or others, which then required public health professionals to be diverted from what they were currently doing or to get up at 2 o'clock in the morning, the downside risk is that we would take away scarce resources and basically be diverting them for no additional benefit. I think we'd end up with a net loss to the system rather than a net gain.
