Look at the entire continent of Africa. A high seroprevalence of SARS-COV-2 antibodies, and yet these mostly underdeveloped nations have a much lower death rate even if you count excess deaths due to poor reporting than the US with supposedly all the best to fight it. My thought is that statistically Africans are thinner and get outdoors more than their obese, diabetic, and hypertension-suffering peers in the US and Europe sitting on their couches. I tested 113 a full year after my COVID-19 infection on an IgG test when 15 or over is considered a positive antibody test. I am going to get tested again when I return from Saudi back to the US a full two years after my infection. I bet I am still in the 80s or thereabouts. And I have not had a second infection. I am fit, do not suffer from hypertension or diabetes, and I had COVID. These are solid, scientific factors that put me in a lower risk category even if I get COVID again.
