The wastewater monitoring reminds me of the maximum allowed levels of Cesium, Strontium and background radiation in berries, mushrooms and reindeer-meat.
I was a child of 4-5 years back then, and I 'recall' some of the madness, which went like this: 'don't play in the sandbox' or the like, because Chernobyl.
Any comparison with Covid about the sheer nonsense, esp. to children, makes me shiver.
A mask (or a scarf or a bandanna or pretty much anything) held before the mouth when sneezung will of course stop droplets flying about - remarkable science that, I expect a Nobel any day now.
But against virus-sized particles? Does nothing. Not FFP2-masks.
Need a full bio-hazard mask with separate I/O-airflow and overpressure for that.

They didn't exist /before/ Chernobyl.
Very keen observation.
