There's two critical cases, for all I know they could be hooked up to ECMO machines and dialysis at the same time, and have no chance of recovery - but even if they die, the stats from Germany are still an outlier.
To estimate this, you need to know the medical (pre-)history and their age. The permanent risk (in general for such kind of infections) for 80+ is still 15%.
>>> Coming back to the two mentioned critical cases - unfortunately they have died today.
- Age 89, female, pneumonia caused by the corona virus.
- Age 78, male, pre-existing conditions were diabetes and coronal heart disease.
Sad to say but those two cases are covered by the 15% statistical risk and/or the 2% risk for people with pre-existing condition and an age below 80yrs.
