Even with safe distances, if no one is masked, after 4 hours talking in a closed room, almost everyone can get infected.

If everyone wears a mask but spends 4 hours talking indoors with no ventilation, many are still at risk of infection.

If everyone is masked, and they cut the time spent talking together by 50%, and there is good ventilation, less than one will be infected.
