My 94 yr old MIL just died of it...so they say...NOT ONE PERSON at her assisted living place (staff or residents) tested positive...and yes, she had other issues. A neighbor couple both had it (68 & 69 yrs old) It lasted 24 hours.
I tested positive to COVID, had a VERY low grade fever for 5 days. My wife tested positive with a prick of the finger and a nasal swab. She had NO symptoms. I think a LOT of people have had this, and have never been tested to prove it.
