> This would have entailed no one working at grocery stores, no deliveries, no travel, no global trade. I just don't buy that this was ever plausible for however long people suggest: 3 weeks, 6 weeks whatever.
The experiences of (at least) New Zealand and Australia are clear evidence it is absolutely possible, without the absurd extremes you are talking about.
If I had to guess, I would guess that COVID can be transmitted by fomites, especially if kept cold, but that it’s extremely rare. In a place like the US or Europe, this is insignificant: your chance of getting seriously sick due to touching something is negligible, and the rate of additional cases due to this effect is inconsequential for public health. But in AU or NZ, where the background rate is essentially zero, a single reintroduction is a big deal.
Right, so why would the US - with much more porous borders - somehow do better?
But, beyond the fact that the US has large land borders, the US has a genuine problem. We are economically dependent on legal and illegal cross-border seasonal migration. I personally think that, with actual political will, the borders could be made a lot less porous, but this would involve attacking the supply and demand sides. Neither party is interested.
I don't like the previous administration one bit, but this was a really hard problem. By the time covid was taken seriously I think it is confirmed it was a least spreading in Seattle and Bay Area.
This reads like Covid arrived in the US through uncontrolled land crossings from Canada or Mexico? I'm pretty sure like Australia and NZ, it came by land and sea mainly.
> Also US has different states with different rules, but no ability to restrict travel between the states
Also Australia never had seen states close borders before. Yet somehow each of the 6 states and 2 territories managed to get legislation passed to do this, get police mobilised, and just got community buy-in that was going to work.
