We know ~98% will recover. The problem is how many simultaneously are sick.
Yet another problem to ponder. From Iran we now have numerous videos of people who have collapsed in public. That certainly cannot be good for their head. Hitting concrete and all. The good news is ambulances and police were still running as of yesterday in most areas.
~98% will survive. One of the lessons from SARS and now COVID-19 is that those who suffer ARDS, one of the primary causes of the fatalities in SARS and COVID-19, are likely to have long term cardio-pulmonary damage.
