The World Health Organisation (WHO) has thoroughly debunked the "crazy conspiracy theory" that coronavirus can be spread by 5G.
Fake news stories and rumours incorrectly suggested that COVID-19 was spreading via 5G mobile phone networks, with even Eamonn Holmes appearing to back the strange theory.
There were reports of criminal vandalism against 5G masts and telecoms workers being threatened and abused.
Numerous experts have explained that the story was false - with NHS England's national medical director, Stephen Powis, calling it "complete and utter rubbish, it's nonsense, it's the worst kind of fake news."
Now the World Health Organisation has also addressed the 5G story.
Facebook users who have interacted with the "harmful" misinformation concerning 5G and coronavirus are being directed to a "mythbusters" page on the WHO website.
It says: "Viruses cannot travel on radio waves/mobile networks. COVID-19 is spreading in many countries that do not have 5G mobile networks.
"COVID-19 is spread through respiratory droplets when an infected person coughs, sneezes or speaks. People can also be infected by touching a contaminated surface and then their eyes, mouth or nose."
As part of its latest efforts to tackle fake news, Facebook is warning users who have interacted with false claims, and directing them to the WHO mythbusters page.
It debunks various false stories, explaining that catching coronavirus does not mean you have it for life, that being able to hold your breath for ten seconds does not mean that you don't have coronavirus, and that drinking alcohol does not protect you from coronavirus.
