Yea, I know it is ~1.5% for confirmed cases. I just doubled it for the asymptomatic. Point stands, why OP is "surprised" they are part of the >95% who have not had Covid (confirmed or not) is bewildering.
And to take the analysis a step further, those are cases since they've been tracking (~ 5 months). The CDC is estimating that most cases are contagious for
up to 10 days, so if we accept that upper number as average to be conservative, it would mean (I think?) that the odds of a person being contagious at the time you meet them (using your 3% estimate above), would be 5 months ~ 21 weeks = 147 days, so then multiply the 3% times 10 days out of 147 days = 3*(10/147) ~ 0.2%.
So only 2 out of every 1,000 people you come across might be contagious, and you probably only come into close contact with a small % of that group.
EDIT: OK, some posted that
USGrant1962's doubling of the 1.5% might be too conservative, but even if add another 5x factor, that brings it to just 1 out of 100 people at any one point in time. And even if you got close enough to be exposed, that doesn't mean you will contract it.
I'm trying to be careful, but I'm not going to extremes (and that's not a judgement on those who are going to extremes, it's a personal, and often completely rational choice, especially if you are at greater risk). In the past few months there's about 15 people we've been in contact with for some extended time. We limit our shopping, wear masks when it makes sense and social distance as much as is practical. So our contact outside that group is minimal.
I'd be surprised if I did get it, not that I didn't! I'm guessing the media hype is getting though to people (not to say it isn't a serious concern, but the media does often go overboard on anything they decide to cover).
Heck, my DD is a nurse, has been assigned to the COVID floor for months now, and I think (I'll have to ask for an update to be sure), the only case among the workers there was an (singular, one) ICU nurse. DD's
in contact with people who have COVID19,
36 hours a week,
12 hours at a stretch,
inside,
for months now, and hasn't caught it. I think our odds are pretty good if we take precautions.
