I find "Plain and simple" a huge generalization of total incompetence in this matter. First, we create a syndrome (CSS) to cover the symptoms of Long Covid and label it an incurable illness that people will have to live with because no one wants the liability of treating it. Then we blame it on our immune system (Mother Nature creating cytokine storms with our immune system. ) Not asking Why? Not testing to diagnose, or for that matter just considering its potential causes. Why not call it Long Covid Syndrome - Don't Bother Me With Your Complaints - Because I Don't Know and Don't Want To.
