The idea that there is a link between COVID-19 and 5G networks looks like a conspiracy theory to me. The article in the link uses many impressive-sounding "sciencey" words in ways which are meaningless though many of the usual villains get a mention (Big Pharma, etc).

COVID-19 has been sequenced in many labs. There is nothing remarkable about its sequence. It poses a potentially very serious public health problem world-wide, including in countries which do not have 5G networks.
