Episode 21: Dying of Thirst - Cholera in the Age of Abundance
In this episode, Heather unpacks one of 2025’s most urgent and underreported global health crises.
Cholera—an ancient disease we know how to prevent and treat—is resurging across dozens of countries. But this isn’t about biology alone. From Sudan’s displaced families to Angola’s overcrowded clinics and the gold fields of the DRC, people are dying not from mystery—but from neglect.
You’ll learn what cholera is, how it spreads, how communities are stepping up where systems have failed and why that isn't enough.
