No idea.
Doug:
The numbers can tell you the story.
If the virus was allowed to work its will uninterrupted it would take a month and a half to infect anyone that could be infected.
To the extent social distancing slows that down, it will take longer.
At this point my guess is that the school year is over for this year.
These two or three week shutdowns seem silly to me because nothing will get resolved in such a short amount of time.
I expect these initial shutdowns will be extended four weeks and then another four weeks at which point people will say "Screw it. I can't live like this." Things will begin to slowly get back to normal. But, the disease could catch fire again, which I think is probable because "herd immunity" won't be established yet.
