Social media is awash in bad takes about the outbreak and platforms have begun to combat that misinformation.

Facebook said Thursday that people will begin seeing warning messages in coming weeks.

That hasn’t stopped the spread of bad information.

Conspiracy theories about the origin of the virus and the vaccines being developed to prevent it still pop up daily. Posts or videos that promote unverified treatments and cures have raked in thousands of views.

The group found more than 100 pieces of misinformation about the coronavirus on Facebook, viewed millions of times even after the claims had been marked as false or misleading by fact-checkers.

Facebook partners with news organizations around the world to provide fact checks of misleading content on its site. The Associated Press is part of that fact-checking program.

“Coronavirus misinformation content mutates and spreads faster than Facebook’s current system can track it,” Avaaz said in its report.

Last month, Iranian media reported more than 300 people had died and 1,000 were sickened in the country after ingesting methanol, a toxic alcohol rumored to be a remedy on social media. An Arizona man also died after taking chloroquine phosphate — a product that some mistake for the anti-malaria drug chloroquine, which President Donald Trump and conservative pundits have touted as a treatment for COVID-19. Health officials have warned the drug hasn’t been proven safe or effective as a virus therapy.

The side effects of chloroquine can be dangerous.
