(and as a disclaimer - I have had asthma on and off since I was a kid and have an as-needed albuterol inhaler and one of my nieces has a nebulizer)
--is her statement of being "asymptomatic except for... <fill in a common symptom>" knowing that she has tested positive. I.e., she is experiencing a known symptom of COVID-19 which is different from someone who might be having an exacerbation (I have been there done that and IV steroids really do help). I would prefer seeing the use of a term like "mildly symptomatic" rather than claim to be "asymptomatic", which it seems the media has insinuated to the public means "no symptoms at all" (because you're not being carried out of the house on a stretcher and shoved into an ambulance).
The scarier thing about COVID-19 is that the symptoms cut across many of the major organs of the body, where in some cases the lung issues become the last thing it impacts. Depending on the viral load, your own body's biology, and where the entry point is and where the landing points are when the virus gets inside, the virus could end up in your digestive tract, causing one of the common symptoms of what my family calls "double bucket" (nausea, vomiting, diarrhea). Or it could end up on your kidneys (in extreme cases, causing kidney failure).
At this point, I think that anyone who is "out and about" (whether by requirement like a public official or frontline worker) or by choice (because they are "bored at home" ), they need to re-calibrate their idea of how bad this thing can be and how it can be spread.
