My brother had it very early on in the spring. He's in his mid-30s and in reasonably good shape with no comorbidities...he had a rough couple of days but is mostly fine now, though he says if he works out too hard he does get sort of winded faster. He's donated plasma I think 3 times since his diagnosis and still had antibodies as of November 28.
A month or two ago, it went through my aunt's (my dad's sister). Per my dad, they were still having family get togethers like everything was normal. My aunt went to the ER a few times but was turned away because she wasn't sick enough...she's recovered and has since tested negative. My uncle was in the hospital for awhile, as was his mother. His father passed away from it. I know others on that side of the family had it as well. Not sure if they have any lasting effects.
My mom tested positive for it 2 weeks after Thanksgiving (after that side of the family got together for Thanksgiving

) and had symptoms (headache and sore throat) but then got an email from the hospital a couple of days later saying the result was a false positive.
A teacher at my son's daycare had it at the end of November. Thankfully it did not spread to anyone else and I was impressed with how they handled it.
