This doesn't seem like news. The major purpose of masks is to vastly decrease the wearer's putting coronavirus spray in the air. Masks have been a big part of fighting the bug since Wuhan.
I think the new info here is the degree to which the virus can travel and be persistent. If 6 feet is simply not enough, and the virus hangs in the air for hours, we're in a new ballgame. Most of the indoor recommendations become moot, except for masking.
Ventilation may help for indoor places, reducing that persistence, so I heard.
