>> What I'm curious is about is the percentage of people (younger or otherwise) who either develop no symptoms or develop symptoms so mild as to not be attributed to the virus. Do such people exist?

My spouse and I both work in a hospital. She got covid and so did one of our two siblings. Neither of them had any symptoms (spouse is in her 50's, our sibling is twenty plus.) I never got it nor did our other sibling. I also don't have antibodies. Go figure... it makes no sense to me.

As a side note: we are not in patient care, however when this was at it's early peak here in the States--I don't know how the nurses, aides, and doctors were able to do their jobs everyday. It was fricken scary walking through the halls and passing workers dressed in plastic; what with all the unknowns at that time, and the news reports of death throughout the world. Those workers deserve respect if not outright awe and a Huge Cash Bonus... Huge.
