I'll start, and maybe Brigitte or Jennifer can pitch in on the aspect of where we are.
What we are talking about is in terms of the Auditor General looking at a whole spectrum of how many of those positives, which we could not tally, were actually contacted. There are a couple of pieces that I want to mention.
There were sometimes errors from the ArriveCAN app in terms of what they actually put into the electronic registration or the registration for the test, which did not enable us, at the very beginning, to immediately confirm that they were the same. Secondly, at times there were situations in which the results were received a little beyond the 96 hours, given that there was more of a virtual test, and it took time for us to really coordinate that.
However, we tried to reconcile the results as best we could in having an ability to really follow up, as I mentioned, through different layers, such as, for example, calls for all the others to do the right thing, to remind people that if they had been travelling, they needed to quarantine.
Brigitte, I don't know if you want to add anything to that.
