Face coverings that are fitted and worn properly can and will reduce transmission.

Prob like a 10mill research.. Me with 10 volunteers; 5 with masks 5 w/o; Everyone into the cold box, breathe normally; You all see how much your stank breath travels without a mask. Ok now let’s all get houses with the 9,999,900 left.
