Whatever your view of PCR testing, if we assume it's applied consistently among travelers and non-travelers, then only 1.5% of returning travelers tested positive, which is a fraction of the overall poisitivity rate in Canada. So, the question is, should Canadians now be urged to travel abroad? https://torontosun.com/news/local-news/only…
keep in mind that 1.5% is not what it looks like. you had to take a PCR test to get ON the plane as well, and anyone with trace/viral fragments would have failed.
so this is the positivity number for people who passed a test a couple days earlier and therefore likely represents the flay out false positivity rate of the test, not the false clinical positive rate (which WOULD be in the domestic numbers)
makes for very different math. these are not independent variables.
