Some preliminary numbers are being put together, but time will tell.

3. The median incubation period is 5 days. So without symptoms after a close exposure for a week or so, you likely aren't infected.
4. In the US you can see numbers of cases (+ tests) rising rapidly. That doesn't mean the numbers of cases are increasing that rapidly. It means more people are getting tested.
5. This germ does not appear to be spread as easily as feared, but I were elderly (80+), frail, overweight, or with significant pre-existing ailments, I would self-quarantine for a while. Not sure what "a while" means, yet.

7. My expert medical friends tell me we'll have a good idea of when the infection rate will plateau or begin its downturn in the next 5-10 days. Can't go by "cases," though.
Addendum: For those who chose to be quarantined at home, we recommend several activities: Sex, home workouts, taking hikes or runs outdoors, reading Maggie's, doing one or two of The Great Courses, getting some outdoor clean-up done, doing an hour of paperwork, cleaning some closets and getting rid of junk, and having civilized cocktail hours. All sorts of ways to make the most of it. Churches are live-streamed now, so that too.
