Lets say a person with the virus approaches a smallish store or enclosed building. Before they open the door they take a big drag on their cigarette and flick the cigarette away. They enter the building and exhale their smoke. If I’m in the building and smell their exhalation, am I also getting dosed with their virus? I guess I’m asking if the virus travels (in the air) the same distance and pattern as the particulates of the cigarette smoke.
My uneducated guess is that smoke particles are smaller and lighter than most of the droplets that carry Covid. I know I can defiantly smell smoke longer away than 6 feet, but we have been told that six feet is far enough away that most of the droplets have fallen or have dispersed enough to be less dangerous.
Bumping because I heard an expert address this.
