Yes.
The concept is that you go to lower-epidemiology or lower-instance countries, and therefore your risk is not dissimilar to my risk of driving to Toronto and then driving to Hamilton on a daily basis in that sense.
Certainly, with regard to countries like New Zealand and Australia, I think there's some validity there. The problem is that you have to be very in tune with the epidemiology of what's going on. There are regional outbreaks that occur in many different places. There are countries where we just don't know the epidemiology. It's interesting; some of the work from the McMaster study is starting to reveal some of these travellers coming back from countries that claim very low incidence but that are actually probably higher than we expect.
The reality, as well, is that I can't fly to New Zealand on my own from Pearson. I have to hop off at an airport, probably in Hong Kong or Dubai or somewhere along those lines. Fine, you were in a low-incidence country, but you stepped into a high-incidence country in an airport and hung out there for 12 hours and then came back.
