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.

That or they’re a hermit.

There are plenty of immunocompromised folks who have continued to be vigilant and likely haven’t caught it.

But generally, yeah. If you are in a city and haven’t been taking precautions you had it, you were just asymptomatic.
