It’s hard to imagine what the world will look like when COVID-19 has passed. So in this episode, we look back to the years after 1918, at the political, artistic, and viral aftermath of the flu pandemic that killed between 50 and 100 million people and left our world permanently transformed. This episode was reported and produced by Rachael Cusick, Tad Davis, Tracie Hunte, Matt Kielty, Latif Nasser, Sarah Qari, Pat Walters, Molly Webster, with production assistance from Tad Davis and Bethel Habte. Special thanks to the Radio Diaries podcast for letting us use an excerpt of their interview with Harry Mills. You can find the original episode here.
