(“Large number of invalids" is my interpretation.){like I said, a clear exaggeration}
I have a friend who is a nephrologist who has been working with COVID patients since March 2020.
Those who have major kidney issues (related to COVID) {notice the word “related” which not the same as “caused by”}. and manage to survive often do not regain kidney function. Many will be on dialysis for the rest of their lives and will not be good candidates for kidney transplants. (I just confirmed this with him last night).
Yes, that's the most common problem. But (brain fog (mental acuity issues) remains for an indefinite, possibly permanent basis.) {notice the undefined “possible” as well as undefined % of people who experience the “brain fog”.}
(If one has lung issues from COVID, there is a reasonable chance the lungs can be permanently scarred. No one knows what the long-term effects from COVID will be, but scarring doesn't go away.) {notice the “if” and undefined “reasonable chance”}
And so, throughout, the fear mongering of “possible” hurried long term effects designed to scare everyone into compliance.
He referred me to this Lancet article that came out two days ago.
