“I had it at the beginning”
My experience matches your experience with other people
Of course I haven't run into the other people who are out, have had it, and aren’t leading with that
So we wouldn't know
Its like the silent vegans that prepare their meals and you just don't notice. They're out there, in theory.
My fam ended up with it. Was early enough we just did not do what we needed to do. So we all were down for that month.
Outcome?
Ended up being ultra conservative about it. Still am. Older people in my life are at risk. And our symptoms were no joke. Mine were the worst of the family.
That said, my experience is similar. I see way more people failing to be at least prudent about it.
Many just do not want to be bothered, and or feel strong motivation to grab onto any rationale that can keep them active.
I don't blame them. The lock down really sucks.
If one can work from home, has no children in public school, lives in the sticks and restricts themselves to necessary trips to the grocery store only, then your risk of getting it is rather lower than if your work is 2 minimum wage jobs with lots of customer contact (say you work at a grocery store in a densely populated part of a large city etc.), you have to take public transport across town to get there because you can't afford a car and your kids are at a public school in the worst district with huge class room sizes and less than ideal 'clientel'.
That's a big contributor to why I won't blame people for playing it differently.
That implicitly assumes equal opportunity for exposure for everyone. This seems rather implausible.
You have to be exposed to it to get it. Lifestyle influences who gets exposed.
That is, if you have had it then you start out susceptible to it. So the cohort studied for this number may differ from that studied for vaccines studies, particularly those performed selectively on people who have not contracted covid.
Of course, I'm assuming here that people have different likelyhoods of contracting the virus given similar exposures. That seems reasonable but I don't know how large the effect is.
