Paul Nicolazzo of the Wilderness Medicine Training Center brings us Part 2 of a two-part series on COVID-19. While Part 1 examined the epidemiology of COVID-19, Part 2 takes a close look at the pathophysiology of COVID-19 and how it relates to its signs and symptoms. After you watch this video, you should understand why some people have only mild symptoms while others require hospitalization, and still, others die.
