After SARS, Chinese health officials built an infectious disease reporting system to evade political meddling. But when the coronavirus emerged, so did fears of upsetting Beijing.
Aggressive screening might have helped contain the coronavirus in the United States. But technical flaws, regulatory hurdles and lapses in leadership let it spread undetected for weeks.
Will we endure 2.2 million deaths? Or will we manage to turn things around?
