What Scientists Got Wrong About COVID-19
Mar 24, 2025•12 min•Ep. 1243
Summary
This episode of Short Wave discusses how early predictions about the slow mutation rate of the SARS-CoV-2 virus were proven wrong. It explores research suggesting that persistent infections in immunocompromised individuals may act as a 'training ground' for the virus, accelerating its evolution. The episode also touches on how COVID-19 has revolutionized virology research and disease surveillance.Episode description
Early in the beginning of the COVID-19 pandemic, scientists predicted the SARS-CoV-2 virus would mutate slowly. They were wrong. Hundreds of thousands of viral mutations and multiple seasonal waves later, we now know why. The answer changes researchers' understanding of viral evolution — and it could help predict the evolution of other viruses in the future. Emily talks about it all with Sarah Zhang, a health writer for The Atlantic.
