The coronavirus has upended most of the world, but there were key warnings about pandemics in general, and the virus specifically, that were often ignored, downplayed or even punished.

Melber also discusses a "Cassandra effect," where some experts who got it right were sidelined and faced alleged retaliation by the Trump Administration.
