Armed internal conflict  in Sudan has created a humanitarian crisis with millions of people displaced both internally and to neighboring countries. Dr. Salim Mohamednour, a medical epidemiologist with expertise in emergency response and the national health coordinator at the WHO country office in Sudan, talks with Dr. Josh Sharfstein about the unfolding catastrophe and what needs to be done. Special thanks to Aseel Salih, Hassan Salih, and Laila Zomorodian, Johns Hopkins Bloomberg School of Public Health students who assisted with the production of this podcast. A note that Dr. Mohamednour is not representing the WHO on the podcast. Content warning: this episode contains depictions of violence. Listeners interested in contributing can consider supporting the World Food Program, the  Sudanese American Physicians Association, and Sadagaat.

The planetary health crisis can’t be ignored in hospitals where patients are sick from climate-driven things like asthma from air quality emergencies, COVID-19 from a zoonotic spillover event, and cardiovascular complications from heat waves. Chris Lemon, an ER doctor and Bloomberg Health Initiative fellow who focuses on the intersection of climate change and health, talks with Stephanie Desmon about his work bringing planetary health dialogue to hospital staff while also looking at ways health systems can lower their massive carbon footprints.

From mushrooms to microscopic organisms, fungi represent a serious—and still relatively unexplored—threat to human health. Dr. Arturo Casadevall returns to the podcast to talk about his new book, What If Fungi Win? which looks at why certain fungal infections take off, why they’re so hard to treat, and why we will most certainly see more of them with climate change and treatment-resistant strains.
