I'm "pure blood" and I had it pretty early on, unless we count those childhood vaxxes decades ago for polio and the like because I don't even get tetanus or the flu shot.

I actually ended up with it three total times, because my job involved travelling a lot, and by the third one it barely even registered. But the original hit was enough to knock me down for 4 days with coughing until I puked multiple times an hour.

But if you never mentioned Covid prior, I'd have assumed it was bronchitis or something and moved on with life. Which I still did because even the "Long Covid" symptom I got passed in a few months, and I already had compromised lungs enough to assume that would happen anyway.
