Re-introduction of the obligation to wear a face mask in NTNM-library

From 20 November 2021, stricter regulations apply regarding face masks:

Since 12 November 2021, wearing a face mask is mandatory wherever you can expect to encounter other persons at any time (e.g. in corridors, on stairs, in waiting areas and in lifts) and where you can therefore not safely maintain the physical distance; now you also need to wear a face mask during all in-person events and in buildings that are accessible to the public and can be classified as customer areas, irrespective of whether the physical distance of 1.5 m can be maintained.
