Multi-billionaire software savant, Bill Gates—hardly the infectious (or any other) disease expert he fancies himself—commented with acid hysteria, several weeks ago (3/24/20), on the mere prospect of lifting draconian “covid19”, Wuhan coronavirus-related shutdowns, to reduce the economic havoc they have wrought:
“It’s very tough to say to people, ‘Hey, keep going to restaurants, go buy new houses, ignore that pile of bodies over in the corner. We want you to keep spending because there’s maybe a politician who thinks [gross domestic product] GDP growth is what really counts.”
Mr. Gates’ self-righteous fulmination, notwithstanding, his morbid, grotesque exaggeration, captures a widely prevalent, critical ignorance of the actual SARS-Cov2 (Severe acute respiratory syndrome coronavirus 2 of the genus Betacoronavirus, which causes Covid19 disease) virus’ lethality embodied in what is known as the infection, or case-fatality ratio (CFR).
Simply and accurately defined, the CFR is the ratio of the number dying from a severe infectious illness, the “numerator,” to the total number infected, the “denominator.” Clear evidence of infection, no matter how severe or mild (even unnoticed by the infected person), is determined, typically, by “immunoassay”, ablood “seroprevalence” test that measures the presence of so-called “antibodies” to an infectious agent such as SARS-Cov2. It is understandable, during the early throes of an outbreak like covid19 disease, that rapid tests which detect (ostensibly) “live virus antigen” (i.e., specific fragments of its genetic code “RNA”), in readily accessible body fluids (eg., from the throat, or mouth), among the most ill, are prioritized, often to the exclusion of blood seroprevalence antibody testing.
However, this viral antigen methodology, and testing scheme, overrepresenting the severe cases, introduces profound biases which may vastly underestimate the “denominator” of total cases, especially the mildest, required for determining an actual CFR. Accordingly, as of 4:30pm, Saturday, 4/18/20, accepting at face value the gross over-counting of covid19 fatalities, absent appropriate validation by Centers For Disease Control(CDC), and individual state (glaringly, out of hospital deaths in New York, and Massachusetts) “guidelines”, the widely referenced Johns Hopkins Corona Virus Resource Center (JHCRC) tallied 37,938 deaths. Applying the concurrent JHCRC enumeration of covid19 cases relying solely on selective “live virus” testing, i.e., 4,690,482, yielded 37,938 deaths/ 4,690,482 cases, a CFR of 1.03%.
