And figuring for the 60% of youth who show no symptoms and the large preportion of mildly symptomatic who are playing "Ring Around The Rosie" hiding their symptoms to maintain a degree of socioeconomic functionality xx the 3% you cite is likely really 10% or higher. Who wants to be a focus of quarantine pressure?
So it's: "Ring around the Rosie (the red ring around the bubonic plague buboe), pocket full of posies (hiding the stench of infection), ashes, ashes,(what you turn into when burned), all fall down.
The really bad thing is that if you or I were to discover miraculous simple treatments today, they wouldn't get published, tested nor commonly used, and in a year or two would be remembered as old wives tales and myth. Our "science" would repress and suppress the science, prevent information dispersal in the name of disinformation busting along with the real disinformation, and even that which was revealed as truly useful experimentally and epidemiologically behind the scenes would be willfully ignored due to powerful conflicts of interest which would conflate whatever it was that was truly efficacious with homeopathic nonsense. Such truth as is determinable is doomed to be ignored, denigrated and forgotten. That is the truth about the quasiscience of modern medicine.
