In my family the only ones that have gotten it in the last year or less is one daughter and one granddaughter. Neither one of them got very sick, just tired and achey a few days.
I’m pretty sure both my grandsons got it when I was in California for the holidays 2019/20 my granddaughter friend had come over whose parents had just come back from China, sick. One grandson was so sick I kept checking him to see if he was breathing. Fortunately I didn’t catch it, even though I was close to them.
My mother stays with my Dad for 24 hrs. Sleeps in the same bed. Take care of him. And she escaped infection. At that time my brother, SIL, niece, and house help all were sick. This infection is very picky.
