I know some people think they have had this but there are tons of respiratory colds and illnesses besides this going around. I know a practitioner who says there are two strains of the flu and numerous colds and viruses, so do not overthink this. I have not been sick this winter but last year I had a major bug twice which made me feel at the edge of death the second time, but I am not sure that would have been it either. I am just not sure so many people have had this without some more tangible evidence.
I hear what you are saying and its important to be cautious regardless, BUT
they even admit most people who have it will have MILD SYMPTOMS
So far
my wife got more sick than ever in her life (headache, shortness of breath, fever) 3 weeks ago
my mother got sick 3 weeks ago, very bad she said
a friend told me he caught flu for first time in his life around January
another friend told me him and wife were badly sick 3 weeks ago
a guy in a class of mine missed class for 3 weeks roughly a month ago
a friends father passed away around late december of unknown causes at the time
Plus I've heard other people on line make similar claims. Yes this could very well all just be the flu, but if all of these celebrities, sports players, politicians have tested positive, despite there being a very low positive rate per population, then it must be that there are far more positive people out there, and even they admit many people likely do not know, and their symptoms will simply pass.
My speculation is that yes many people have this, I cannot conclude but that is my belief.
