Icke has a decent theory on the relationship of Covid to 5G. Basically that 'any' G is exposing your body to increasing frequencies that have never been scientifically studied, but which seem to have a direct correlation to the body's ability to process oxygen. Hence it was worse in 5G cities, and would continue to get worse as they roll it out more. Even in 4G cities, the use of masks is accomplishing much the same thing, i.e. reducing oxygen levels, which exacerbates lung conditions.
