Season 1, Episode 8: The Black Death: history's most famous pandemic.

In this episode of 4Ps, Dr. Kate Martin reflects on the lingering personal cost of COVID—and then travels back to history’s most infamous pandemic: the Black Death. How did plague spread so fast, what does infection look like in the human body, and why does it still matter today? We’ll follow Yersinia pestis through fleas, lungs, quarantine islands, and trade routes—and end with the haunting question of whether the Black Death left fingerprints in our genes.
