Our family just went through this shindig. The wife (early 40s) got sick with what at seemed like a sinus infection the weekend after Thanksgiving, and then seemed to progress to bronchitis. She went in, got diagnosed as suspected, received a prescription for some antibiotics, and got told to not fill the 'script until her Covid test results came back. She popped hot which came as a bit of a surprise, and was told instead to go fill a prescription for an Albuterol inhaler (which is pretty good shit when it comes to opening airways for short duration).
The kids (grade school) and I (mid-40s) went in for testing the next day. Both boys immediately popped positive on the antigen rapid test; I tested negative
PCR test results came back a few days later and all three of us were positive. At no time did the three of us have any symptoms beyond my oldest boy's usual allergies (so maybe his sniffles were actually Covid, but they were indistinguishable from literally every other day of his recent life). No fevers, no fatigue, nothing of the sort; they had 100% of their normal energy, and I continued my daily workouts at home. They got 10 days off from school per the health department. I was never officially quarantined, but with a sick wife and two very energetic kids at home, it's not like I was going anywhere fun.
My wife's progression was not as simple. On Day 6 (assuming that we know the actual date of onset; it's just a guess) she got monoclonal antibody treatment due to worsening symptoms, and Days 7 & 8 were pretty good - she still had fatigue and a cough, but much improved. Days 9 & 10 were rougher as she regressed - the cough got much worse, and her energy sank. On Day 11 she went back due to a suspected secondary infection; the doctor yelled at her for waiting too long to return, and then more or less admitted there's not much that they can do for what was determined to be "Covid bronchitis"
She ended up getting a prescription for some sort of cough suppressant and for Flovent (a longer-acting inhaler) - these medications seemed quite beneficial (particularly in helping her get a full night's rest). We're now at Day 16; she's back to light daily activity and is tapering off the medication, but certainly isn't yet in any sort of condition for serious physical work or rigorous exercise.
So, in summary - one person fairly sick for over two weeks, three people completely asymptomatic
Did our part to flatten the curve (right up against the Y-axis).
