ANd then, there is still hope infection can be cut off at source, so general population risk from quick single exposure is low. And as far as I remember, a few people were taken off the planes and later tested positive, but no large clusters of cases from those. AC had one such event 2 weeks ago; but no follow-up cases.
You cannot have it both ways. Either it is highly contagious and border closures and quarantines are warranted, or it is not.
Unless we are absolutely sure about HOW the virus is transmitted, any statement for or against wearing masks, banning this or that, and locking up people or not is premature.
If as you say a few people on the AC plane were infected, but subsequently all the others on the same plane were and are healthy...then the preliminary conclusion must be that the virus is NOT highly contagious. To give a counter example, just imagine if a few people on that plane had Ebola. I am sure everyone on that plane on arrival at the airport would be dead.
There is no true boundary between "highly" and "not too much". So far, estimates are that average patient infects 3 people over the course of infection. Which is bad - but think about it... most of us interact with more than 3 people a week, so instant infection is not the thing. 3, or maybe 4, is still bad enough, so that serious steps are required. Some people want extreme steps (did anyone suggested to nuke Wuhan yet?). My impression is that a lot of what is done is an overkill. But I am afraid to say that - I am afraid to be proven wrong by future events.
https://montreal.ctvnews.ca/air-canada- ... -1.4824097 is the event I am talking about - and I didn't see any follow-up. It is close to 2 weeks by now, most infections should be recognized.
More information is needed about the AC passenger. Did she simply contract the virus by sitting next to an already infected passenger? Or did she used her finger to shove food into her mouth at an unsanitary restaurant in Asia? And why is everyone else not sickened on that same flight?
