Yes, there are studies about this now. Basically, a FFP mask or (H)EPA filter gets clogged (i.e. no air flow anymore) before it gets ineffective in filtering viruses etc.

Unfortunately current generations of air cleaners do not measure air flow rate to warn you when it is dropping off because the filters are clogged with dust. That would be so useful. Probably expensive, though.
We remove dust every two weeks or so.

Das gilt für eine Reihe von Räumen in diesem spezifischen Krankenhaus.
Wahrscheinlich, weil lokal einfach viel zu viel Infektion läuft.

Die Folgen des Handelns der aktuellen Regierung werden noch nicht zu sehen sein.
Von daher dürfte das überwiegend Covid Folgen sein?

Finding what inside would have proven it is alive? Something squishy?

Wie immer: danke für die Updates. Wie ist es denn mit den Gesamtzahlen für 2025? So viel wie in 2024 oder signifikant weniger/mehr?

Dieses Jahr insgesamt weniger Infektionen? Oder nur verschoben?

I am seriously interested in good interpretations of this song. As a non-native speaker I am not sure I get it. The interpretations I find easily seem to less than skin deep.

you can't just add only computers, you also need blinking lights.

Thats the crux of the problem, we no longer have large blinky
light arrays that flicker suspiciously when something is not right.
