WHO reports globally 3.3 billion. Is that enough for you?
WHO can argue with someone WHO has been to the North and South Poles?
WHO reports 3.3 billion what?? Covid cases, deaths? Whatever that figure, it would represent about 40% of the totaal world population of around 8 billion people.
According to a recent list at worldometers there have been a little under 7,000,000 deaths, and a little under 700,000,000 Covid cases worldwide. See:
