Millions of Tweets Spreading Conspiracy Theories About Coronavirus

Roughly 2 million tweets peddled conspiracy theories about the coronavirus over the three-week period when the outbreak began to spread outside China, according to an unreleased report from an arm of the State Department, raising fresh fears about Silicon Valley’s preparedness to combat a surge of dangerous disinformation online. The wrongful, harmful posts floated a number of hoaxes — suggesting, for example, that the coronavirus had been created by the Bill and Melinda Gates Foundation or was the result of a bioweapon.
