Not a cause of the virus like one or two are suggesting but the media have in their clumsy way have made the issue all about conspiracy theorists claiming that to be the case.
Most people who protest about 5g don't claim it is linked to the virus either. They say there are health issues surrounding the effects of 5g. Others say there should be more testing. Others say put it to the vote. 200 scientists in 2017 also petitioned governments to look into the matter.
I don't know if it is safe or not. All i am saying is it would have been nice to be consulted first.
