> The math tells us that ~95% people will get through this with a week or two of downtime, rendering them immunized against this virus, and then they'll be right back to work.

I don't think this is right. 80% of people should get through this fine if they contract it, given numbers I read recently. The other 20% will have some level of big problems, and if too many of these happen in a given area, hospitals will be overwhelmed and more would die than otherwise.

Furthermore, from what I have read, there is no known long-term immunity to CoV, but maybe a 4-month window of some level of immunity.
