How false hope spread about Hydroxychloroquine to treat covid-19 and the consequences that followed Even before Trump started talking about the drugs, studies abroad sparked interest in them as a potential cure. News about the drugs spread quickly online, percolated to the media and the White House. Scientists have since pointed to major flaws in those original studies and say there is a lack of reliable data on the drugs. Experts warn about the dangerous consequences of over-promoting a drug with unknown efficacy: Shortages of hydroxychloroquine have already occurred, depriving lupus and rheumatoid arthritis patients of access to it. Doctors say some patients could die of side effects. Other potential treatments for covid-19 could get overlooked with so much concentration on one option. The Fact Checker video team has reconstructed how the claim spread online and illustrates the troubling consequences of such misleading hope in the drugs. The Facts Conversation around hydroxychloroquine and chloroquine as potential treatments for covid-19 started in China in late January. According to Kate Starbird of the University of Washington’s Center for an Informed Public, tweets from media organizations — including Chinese state outlets — and investors highlighted past studies in which the medications were tested as cures for severe acute respiratory syndrome. (The 2005 tests never made it to human trials.) They also pointed to statements from the coronavirus research center in Wuhan, China, suggesting the drugs could be used to fight covid-19. Renée DiResta, technical research manager at the Stanford Internet Observatory, found similar trends on Facebook and Instagram in February. The number of total posts and interactions increased, and Internet speculation spread beyond China to Nigeria, Vietnam and France. A large portion of activity online at the end of February and early March appeared in French and centered on a study published by French researcher and doctor Didier Raoult. The spread in the U.S. Raoult’s findings helped bring the theory … Read the remainder of the story and view the video here.
