Africa is already primed for a major epidemic, it is emerging in Egypt, and bafflingly they have not locked flights out of China and Korea yet. It's almost certainly too late now. Iran is currently in a rapidly expanding infection of particularly voracious infection with a higher than previously seen mortality ratio. Hopefully that isn't due to some additional mutation, that would be disastrous indeed.
The recent discoveries that almost certainly prove this thing is both airborne and can spread and atomize out from water sources, combined with the asymptomatic/delayed yet ultimately contagious carriers, means this initial wave is about to look positively tiny compared to the next waves. These factors make for an exponential spread, and many nations simply lack the infrastructure to provide critical care, clean water, oxygen, antibiotics, sub-2nm isolation, etc, for the pursuit of care and prevention.
I spent the last few weeks mostly dismissing this thing as yet another round of what we've seen time and time again, some nasty new illness that turns out to be logically self limiting for various reasons of practicality. Unfortunately for everyone, and to my sincere embarrassment, the case with this virus is definitely not so easily defeated. In point of fact, it's possibly far worse than anyone expected outside of 'crazy' circles.
We'll know a lot in the next 48-72 hours. If Iran, South Korea, and the other accelerating post-China zones continue to accelerate in a geometric fashion, and the mortality rate turns out to be closer to 10%+ than 2.x% as the ChiComm govt was espousing, then we may be looking at many millions of dead as the floor, and potentially tens or hundreds of millions killed.
