On Wednesday, scientists in Demark published a "revolutionary" study that demonstrates mask-wearing does very little to mitigate the spread of COVID-19. By Friday, an Oxford University professor, citing the study in an article published on The Spectator, reported that he was flagged by Facebook for "false information" as he attempted to repost the article on the social media platform.
Before we begin, we want to remind readers that hours after the study's publication in Annals of Internal Medicine, titled "Effectiveness of Adding a Mask Recommendation to Other Public Health Measures to Prevent SARS-CoV-2 Infection in Danish Mask Wearer," we asked a straightforward question of how social media companies would respond to these new developments.
Well, that answer quickly appeared as director of the Center for Evidence-Based Medicine at Oxford University Carl Heneghan tweeted Friday that his article titled "Landmark Danish study finds no significant effect for facemask wearers," citing the new study, was flagged as false information by Facebook.

In the article, published in The Spectator, he spoke about the new study:
"Yesterday marked the publication of a long-delayed trial in Denmark which hopes to answer that very question. The 'Damask-19 trial' was conducted in the spring with over 6,000 participants, when the public were not being told to wear masks, but other public health measures were in place. Unlike other studies looking at masks, the Danmask study was a randomised controlled trial – making it the highest quality scientific evidence."
He continued:
"Around half of those in the trial received 50 disposable surgical face masks, which they were told to change after eight hours of use. After one month, the trial participants were tested using both PCR, antibody, and lateral flow tests and compared with the trial participants who did not wear a mask.
"In the end, there was no statistically significant difference between those who wore masks and those who did not when it came to being infected by Covid-19. 1.8 per cent of those wearing masks caught Covid, compared to 2.1 per cent of the control group. As a result, it seems that any effect masks have on preventing the spread of the disease in the community is small."
