Facebook, Twitter, and YouTube removed a viral video this week because it featured a group of doctors making controversial claims about COVID-19 and its treatments.

In the video, which racked up more than 14 million views before it was taken down, a woman identified as Houston Dr. Stella Immanuel, argued against the government-mandated shutdown and pressed for the use of hydroxychloroquine, an antimalarial drug that may or may not be an effective treatment against the coronavirus. Studies saying otherwise are “fake science” sponsored by “fake pharma companies,” she said. She then discouraged people from wearing face masks, reiterating that we already have a “cure”: hydroxychloroquine.
