Whenever a new community case comes to light, as we saw over the weekend, we do need to take stock. We need to take time to thoroughly investigate that particular case. Now, there are two parallel work streams that happen here, two parallel priorities. The first is to identify everybody that could be at risk because of that case. That is the first and foremost priority. Stamp it out, make sure it's not spreading, so identify that person's close contacts, make sure they are tested, make sure they are isolating. And our systems in that regard have improved exponentially. They continue to strengthen every day, and we've seen that in the fact that we have dealt with a number of cases where we've not needed to escalate alert levels. Our system is continuously improving. So that's the first priority.
