Corona Virus, later identified as COVID 19, further shortened to just Covid . . infected America in late 2019 (I contracted SOMETHING powerful in the third week of November that didn't clear up sufficiently for me to "feel" normal until late March/early April, 2020) and I have conversed with three or four personally as well as communicated with a dozen or so, OTHER senior saints (I was 72 at the time) who also declare a severe flu they had never known before.
ALL of us (as I remember) were the type to have never had a flu shot and other etcetera's.
The lame stream didn't REALLY start to talk about it and scare the stupids, unto Jan/Feb 2020
