Conspiracy theories claiming a connection between 5G technology and the coronavirus have been around since the pandemic’s early days and apparently they’re still going strong.

So strong, in fact, that Twitter began applying a label to some tweets about COVID-19 and 5G, encouraging users to “get the facts” about the virus. As Business Insider reported, clicking through the label leads to a page collecting sources debunking claims with links to pages like the BBC and Snopes. Earlier this year, the conspiracy was linked to a series of arson attacks on 5G towers.
