There’s no way to keep infallible track of people here, let alone outside the borders of the USA.
I’m surprised in the other direction... that it is not WORSE.
I will surprised if it doesn’t end up worse. It seems that there are only a certain amount of beds for isolation and a certain amount of Hazmat type suits for those beds. In other words the world is not awash with preparations for this and don’t seem in that much of a hurry to prepare better or exclude/quarantine those who are a risk. I wonder if once the numbers get above the spaces available for high quality healthcare then will a lot of countries be any better off than West Africa.
