Because all the masks being worn do not filter out any virus'. Besides, if masks really worked and this virus was ohhh sooooo deadly, there would be these canisters at every store, (Entrances, Exits, Restrooms, etc.), least they be fined or shut down.

Why unemployment would decline so much as to be news worthy.
