On the official website of the World Health Organization there is a section on such rumors in which the social media claims about Corona are explained in detail. From the website, there is a post named 'FACT: 5G mobile networks DO NOT spread COVID-19'.
This post clearly states that viruses do not spread through radio wave and mobile networks. COVID-19 is also spreading in countries where there is neither testing of 5G nor 5G mobile network. The corona virus is spread by the infected person's breath droplets when he sneezes, talks or spits. In addition, if the infected person's breath drops on a surface, the corona spreads by touching it and then touching the nose, mouth and eyes.
