In this episode of The Inflection Point, Dr. Dick Zoutman returns to unpack the science behind respiratory viruses, immune function, airborne transmission, and the ongoing impact of long COVID on individuals, health systems, and the global economy.
We break down how viruses mutate, why RSV and influenza remain so difficult to control, and why the air around us is a major—yet underestimated—driver of infectious disease spread. You’ll also learn how long COVID continues to strain workforce capacity, clinical operations, and societal functioning. Clear explanations, evidence-informed insights, and real-world examples make this episode essential for clinicians, leaders, and the public.
