Masks, if worn properly end of the correct type might make a difference but I have not seen concrete evidence. However, no one is wearing them properly they are constantly touching them taking them on and off, reusing them etc. always completely defeats the purpose of wearing one when you were just reused it or touched it with your hands and shoved it in your pocket.
Well plenty of people don’t do full face coverings. It makes me shake my head because I worked in genuinely dirty environments where the mask or respirator does not come off until you are out of the work zone.
My favorite is wearing them under the nose.
The whole thing is a joke.
