“Most will laugh at this scientifically unproven claim, but we should not underestimate public worry about potentially adverse health impacts of 5G due to radiation, and thus a possible drag on the 5G progress in democratic countries,” analysts led by Edison Lee at Jefferies Financial Group Inc. said in a note on Sunday.

While there’s absolutely no evidence to support the idea that 5G technology contributes to Covid-19’s spread, the conspiracy is being shared widely on social media. Mast fires were reported in Belfast, Liverpool and Birmingham, according to local media. A video of a telecom tower on fire was circulated on a Birmingham community webpage, and Facebook removed a group which encouraged users to share footage of equipment being destroyed, the Guardian reported Friday.
