(Relevant) Stella Immanuel is a Houston doctor who’s become a minor celebrity on more conspiratorial internet corners, largely for espousing her contrarian views about the effectiveness of masks in stopping the spread of the coronavirus and praising the use of hydroxychloroquine to treat COVID-19. Both of beliefs have been debunked by the overwhelming majority healthcare experts, but that hasn’t stopped Immanuel’s videos from racking up millions of views and even getting praise from Donald Trump Jr. (“must watch!”) and a retweet from President Donald Trump himself.
