The world continues to learn about this sometimes deadly new zoonotic virus. We know now from NYC that it is disproportionately serious in males (61% of tested symptomatics), more fatal in people over 65 (63%), and is disproportionately lethal (84%) in people with especially the comorbidities hypertension (55%), diabetes (35%) and obesity (50% of serious/critical [s/c] hospital admissions in NOLA, under 60 years old 2x s/c in NYC). More on the significance of these facts is developed below.
We know from two inadvertent extreme ‘lack of social distancing’ “experiments”, Diamond Princess (DP) and CVN71 (Theodore Roosevelt, TR), that only about 15% (TR) to 19% (DP, with several more weeks of exposure) ever test positive for the virus. That means that something like 80-85% of people have an immune system that seems to handle the virus effortlessly even in highly infectious, high viral titer circumstances–so that not even a positive viral shedding test develops. This could just be a very good innate immune system; it could also be a primed active immune system (i.e. the population was NOT naïve). A very plausible explanation hypothesis is developed below with important ramifications for opening countries from extreme lockdown measures.
