Yes. Absolutely. On the 0.7%, some of it was related to people who were positive, who were non-infectious but still shedding, who went on a flight and got back to Canada, and who probably got infected in their place of origin, in that sense. Some who were caught there were actually infectious. Yes, that 0.3% got caught a little bit later. These people were incubating on that flight, were negative when they showed up, but after a couple of days back in Canada tested positive.
Yes, there is a part that's missed, which is why you do have to institute some period. Again, with day seven, if you're going to catch most of them, that's probably a much more tolerant period for everyone else. Plus, you're going to catch people who might even be symptomatic day nine or 10, because we know they start shedding on day seven in that sense too.
