"By adhering to strict hygiene measures, it can be expected that the virus concentration in a person infected can be reduced to such an extent that the severity of the disease is reduced, while at the same time immunity is developed. These favourable conditions are not given in the case of an exceptional outbreak event (superspreading event, e.g. carnival session, après-ski bar Ischgl). With hygiene measures, favourable effects with regard to total mortality can be expected."

This is the most interesting part of this and should be discussed more. There seems to be a lot of evidence that viral load is a factor. If social distancing and proper hygiene doesn't just lead to less infections but to more mild infections that's a big dea.
