@RadCentrism China (+others) has demonstrated that dynamic lockdowns can eliminate. Probably also that frequent enough testing and isolation (as per Mina) can also eliminate. No one has really tried it with superb ventilation, but I bet that would be a third way to eliminate.
@RadCentrism 中国（其他）已经证明动态封锁可以消除。可能也可以消除足够频繁的测试和隔离（根据 Mina）。没有人真正尝试过它具有出色的通风效果，但我敢打赌这将是消除的第三种方法。
