How can we as a medical community be less dismissive of the renegade thinkers who are able to see the implications of a clinical problem early? What parallels did you find between what occurred during the early stages of the AIDS pandemic in the United States (based on the film!) and the early stages of the COVID-19 pandemic?

How can disinformation and rhetoric such as "fake news" result in harm in outcomes of controlling a pandemic? Finally, Bill Gates provided some insight regarding the work his organization has done as well as general observations of the COVID-19 pandemic. Consider his arguments, evidentiary value included, and offer a comparison between what Gates discusses as preventative measures to take for future pandemics and what you observed during the COVID-19 pandemic of the last few years.
