For much of the past century, a strategy known as elimination was the gold standard for dealing with deadly new viruses. But China’s abrupt reversal of its "zero-COVID" policy, which took it to an extreme, has cast doubts over the approach and left a gaping hole in the world’s game plan for the next pandemic.
