“It is a real challenge in terms of trying to get the message to the public about what they can really do to protect themselves and what the facts are behind the problem," said Michael Osterholm, head of the University of Minnesota’s Center for Infectious Disease Research and Policy.
He said the fear is that “people are putting themselves in harm’s way because they don’t believe the virus is something they have to deal with.”
Rather than fade away in the face of new evidence, the claims have flourished, fed by mixed messages from officials, transmitted by social media, amplified by leaders like Trump and mutating when confronted with contradictory facts.
“You don’t need masks. There is a cure,” Dr. Stella Immanuel promised in a video that promoted hydroxychloroquine. “You don’t need people to be locked down.”
The truth: Federal regulators last month revoked their authorization of the drug as an emergency treatment amid growing evidence it doesn’t work and can have deadly side effects.
Even if it were effective, it wouldn’t negate the need for masks and other measures to contain the outbreak.
None of that stopped President Donald Trump, who has repeatedly praised the drug, from retweeting the video.
Twitter and Facebook began removing the video Monday for violating policies on Covid-19 misinformation, but it had already been seen more than 20 million times.
Many of the claims in Immanuel’s video are widely disputed by medical experts.
She has made even more bizarre pronouncements in the past, saying that cysts, fibroids and some other conditions can be caused by having sex with demons, that McDonald's and Pokemon promote witchcraft, that alien DNA is used in medical treatments, and that half-human “reptilians” work in the government.
