At this point it's highly unlikely that there remains a human in an urban center that has not caught covid once. Maybe they didn't have symptoms, maybe they didn't notice, but they've had covid.
I live in one of the largest US cities, attend concerts, use public transit, and fly internationally. No covid in this house, and we go through a box of RATs a week. Not immunocompromised, we just don't want covid.
The secret: we wear respirators everywhere and use nasal spray before & after risky situations.
