All those epidemics happened before we had MS Teams and WebEx. The one change I see happening from this is that industries that were hostile to telework will learn to embrace it. No need to pay people to drive to a meeting location if you can just link them in from wherever they are (oh, and people will eventually learn how to 'mute' their microphone while they are on a conference). Our hospital cafeteria being a good example. The moment you get up, someone with a small bucket and a rag comes over to wipe down the table. I doubt that luxury will remain. Finally people keep a few steps of distance while you stand in line or even while you try to pour yourself a cup of coffee. Not sure why people have no sense of personal space.
