People are touching all kinds of surfaces and touching their face and eyes and mask etc. All the plexglass and masks and distance little good if everyone is touching the same gas station pumps, atm machines, counters tops, etc without proper hygiene / sanitization.
I am thinking it is more likely to “catch” something by touching things then breathing it in.
Most studies are showing the virus doesn’t last long on outside surfaces though. Especially in the sun.
