I have once or twice. It used to be joked about in movies and sitcoms. I thought it was pretty much common knowledge until this year. I couldn't tell you how many times i have heard. "I tested negative, but I lost my sense of smell, so i am pretty sure I had it." Maybe people are rationalizing, why they tested negative, but were told to quarantine anyway.
I was struck yesterday, while shoveling compost, by something else. When I was young, 5 or 6, my mom got pneumonia. We don't really know what from. "Unidentified respiratory infection." Pretty common also. It left her with asthma for the rest of her life. This year, that same situation would be touted as permeant damage from COVID-19.

"There is nothing new under the sun."
On a side note, she is darn near 70 now. She has been treating her asthma holistically, and has been off an inhaler, she was told she could never stop using in her 30s, for almost 5 years now. She is teacher, and she was pissed last year when they closed schools. She is pissed this year about the stupid shit. She can't wear a mask due to her asthma. She hasn't missed day. We have been full-time in person, full staff and student since about 2 weeks into the school year.
