This is a first analysis on documented cases of the LEOSS study on the epidemiology of SARS-CoV‑2.
More than 20 research teams working on comprehensive analyses using the LEOSS data. A public data set is now available. All scientists are invited to register to get access to the more extensive scientific data set.
Note, in the following diagrams, we present descriptive analysis. This means, in the graphs, the distribution of values is pictured for each clinical phase separately. The data of one patient is e.g. included in the distribution for the uncomplicated phase AND the complicated phase. A cause-effect analysis is not yet performed.

* Recovery phase in outpatient settings can be achieved by uncomplicated patients after 14 days of observation without disease progression.
We excluded cases with ongoing documentation in the following graphics.
