My perspective is someone in Seattle that had the worst asthma attack of my adult life a month ago. Literally couldn't breath well enough to talk for about a week with fever several nights. I've now seen my family get all symptoms but the breathing difficulty, fevers included. We can't get tested, as they are still mostly stonewalling. And I would likely be negative, even if I had it, at this point.
So, if I had it, and my family did too, why did I get severely hit, but they did not? Best I can fathom is baseline lung health.
Would love a better hypothesis. Or more tests I can look at.
