1. I have no idea what the typical interval is between onset of symptoms and death, for those that die.
The apparent discrepancy you mention in the numbers may be due to many of the infected currently being neither dead nor recovered.
I’m guessing we will know more about rate of recovery when it has been in other countries a while. I would think worse case scenario from a healthcare standpoint (other than high CFR obviously) is if it takes weeks in an ICU and/or on a ventilator.
