There are fears that 5G wifi networks could be acting as an ''accelerator'' for the coronavirus pandemic.
A new conspiracy theory claims that the symptoms of the virus - high fever, coughing and shortness of breath - is the human body responding to exposure to 5G.
Tanja Rebel, an anti-5G activist and philosophy lecturer at the Isle of Wight College, said: ''Many studies show that Electro-Magnetic Radiation (EMR) suppresses the immune system and that it helps viruses and bacteria thrive.
''So EMR and in particular 5G could act as an accelerator for the disease. We do not know for sure, but common sense and the precautionary principle decree that we urgently need a moratorium on the roll-out of 5G until we can show that it is safe.''
The theory has been met with scepticism by experts, with the UK's independent fact-checking charity, Full Fact, saying: ''This is incorrect, the new coronavirus is a virus and there is no evidence that 5G is harmful to people's health.''
