Not really, China just had unexpected quarantines with no info on end dates and letting the public figure out how they were going to get supplies to keep alive for the duration.

I think there are several issues, it can be done but it would require massive amount of planning, which like you said would make it almost impossible.

If we look at the COVID response and past pandemics, its very sudden and catches people out and causes mass panic (everyone going out to buy toilet paper). As no one knows/knew how long the lock downs would be.

However, if we announced it beforehand, informing the public of the duration of the quarantine. Set up supply drop offs, re-assure the public that there won't be supply issues, account for basic contingencies, it could be done, but it would require an almost militaristic amount of planning and logistics.

I know it's unrealistic, asking as a hypothetical because there will always be an exception.

I do wonder, in a perfect world if everyone adhered to a three-week quarantine, just how many different strains of viruses or bacterial diseases we could have eliminated.
