This is why you should not shoot your mouth off on social media and talk about things you don’t know about.

Yesterday, Vox Media deleted a tweet from January that assured followers the coronavirus would not be “a deadly pandemic.”

“We have deleted a tweet from Jan 31 that no longer reflects the current reality of the coronavirus story,” tweeted Vox’s account, linking to the rest of the site’s more current and accurate coronavirus coverage.

The Wrap writes that Vox wasn’t the first media company to address a coronavirus-related tweet’s deletion on Tuesday.

MSNBC, too, issued a correction and retracted a tweet that misquoted host Chris Hayes as saying the coronavirus pandemic had the potential to kill “50% of the population.” The Monday tweet linked to an article on MSNBC.com, tagging Hayes’ account and misquoting him: “There is no option to just let everyone go back out and go back to normal if a pandemic rages across the country and kills 50% of the population.”

The network later removed the erroneous post and explained why it was inaccurate. “Correction: The quote tweeted is incorrect due to an editing error,” tweeted the account Tuesday, featuring a screenshot of the original tweet. “It should read: ‘if a pandemic rages across the country and infects 50% of the population, and kills a percentage point, at the low end’.”

“Editing error”? OK….let’s go with that.
