Okay, let's use the world's population. The NIH estimates that approximately 9% of the world's population is infected with the flu each year. So, according to this report, we can expect about 2700% of the world's population to be infected with COVID-19.IMO we should use the world's population as the upper limit. The claimed number might be off but it's incredibly high because of the stealth onset of illness allows for highly contagious young, active asymptomatic people to mingle for long periods of time before we see a upward trend in initial symptoms in those at risk.
The claim makes no sense.
