I wonder why he believes that 40-70% of the world population will get it within one year. Right now it doesn't seem like this will happen. Chinese numbers don't climb that fast anymore. You have some thousand new cases per day but that was the same a week or two ago.
And I also can't believe this will happen in Northern America, Europe, Australia and so on. I guess it could spread super fast in as example many African or other very poor countries, though (if it survives the temperatures there)
