This isn’t about over-reaction or under-reaction, but mis-reaction. For example, sending janitors rushing into closed schools and other buildings to sanitize them poses much more risk to those janitors — and anyone they later come in contact with — than leaving the buildings empty.

And if you leave your apartment building to go running, there’s more danger in your shared elevator than in the great outdoors.

Such distinctions are important. There’s abundant evidence that we are going to be contending with this thing not for days or weeks, but for months.
