The idea is that PEOPLE WHO DON’T HAVE TO TAKE THE SUBWAY SHOULD NOT TAKE THE SUBWAY, thus allowing the subway-dependent folks more room to physically distance themselves from each other.
For example, one of the FOX News medical contributors, Dr. Jeannete Neshwat, who is on the front line treating Chinese FrankenCOVID patients, keep complaining about how the subways are so crowded. I’m thinking, you’re a doctor, couldn’t you afford to take a cab or drive home or even walk home - the last one an admittedly tall order, given what De Blah Blah Blah has done to the city. Furthermore, after treating COVID patients all day, in spite of whatever precautions she takes before leaving her office or the hospital, she could still have gotten a snootful and could shed it on the subway during subsequent days before showing any symptoms.
Nobody takes the subway right now except people who really have to. People basically hate the thing.
You are right about the possible contagion. My SIL was an ob/gyn nurse and always went straight to the shower when she got home from work, even though she did not work in a contagious part of the hospital.
Every time I start to feel weird about this whole thing I remember that I am not on the front lines.
