When we talk about El Niño, we often think of rains, floods, or droughts. But its effects go far beyond the weather. In this episode of *Hablemos de Salud* (Let’s Talk Health), we speak with Daniel Buss and Ciro Ugarte—two PAHO specialists—who explain how this phenomenon can increase the risk of disease, intensify heatwaves, affect food security, and put pressure on health systems. Learn about the main health risks, which populations are most vulnerable, and the measures countries and communities can take to prepare for and protect themselves against the impacts of El Niño.
