> Why _doesn't_ an ultra-strict lockdown for this long prevent spread (and allow existing cases to resolve)? It works, but 3 weeks is too optimistic. You need to deal with noncompliance, spread within apartments, and essential employment which adds additional time to achieve to 0-COVID. I live on the Isle of Man, which successfully introduced a 0-COVID policy in 2020 (imprisonment for breaching restrictions) and subsequently removed all COVID restrictions once 0-COVID was achieved. > Throughout 2021, I had sort of told myself that most of the harms of the pandemic were optional ... evidently that's not true. Why not? Since it's infeasible to enforce a 0-COVID policy globally, strong border restrictions are required. With strong border restrictions, 0-COVID isn't economically viable long-term as it permanently affects any industry relying on tourism or travel which causes structural unemployment if left unchecked; very few visitors are going to accept a 2/3 week quarantine on arrival unless there's a large incentive.
