Zack, Jenn, and Alex talk about the global spread of the idea that hydroxychloroquine can treat coronavirus. Americans know it as Trump’s favorite drug, but the idea actually started with a famous contrarian doctor in France — and its most fervent acolyte in politics is the Brazilian president, not the American one. They talk about how faith in the drug spread globally, despite a lack of evidence and considerable reason to worry about its side effects, and how it exemplifies a style of politics that academics have termed “medical populism.” References: The Guardian has a great story on the origins of how hydroxychloroquine became a global phenomenon. Here’s that study on “medical populism” we talked about so much. Populists around the world are turning to hydroxychloroquine, reports the Washington Post. The New York Times has a thorough profile of French doctor Didier Raoult. You can find the video of Brazilians singing about the drug to President Bolsonaro here.
