COVID-19 USA--The Incredible Shrinking Mortality Forecast--TASK FORCE AWOL


IMMEDIATEREL//@TCNT//CD///URGENT//CMDMSGCTR//DECLASSFD



    (The Lobby)-- In something out of a ' 50's B-rated sci-fi cult movie, Erin Allday of the  SF Chronicle reports 10 hours ago;
     " 'Most of the public wants to know: Just tell me what happens at the end of the movie,' said Nicholas Jewell, a UC Berkeley biostatistician. He appreciates that desire, especially in a time of so much uncertainty. But that’s not what models are for."


     Like Scott Carey (Grant Williams)  in  The Incredible Shrinking Man (1957) who encounters the strange fog at the beginning that causes him to eventually disappear into the subatomic universe, so too the coronavirus casualty numbers are shrouded in a cloud of guesswork and data overload. Somehow the world is also hoping the virus will disappear into  microbeworld  before school is out for the summer.
     The Chronicle article then gives a breakdown of all of the predictions since China first shut its Wuhan doors and the disease swept across Italy and Spain. With numbers spiking in southern Europe and the California governor calling for a complete shutdown of the state's economy, the plot began to focus on the White House response. It came in the form of a new cast of characters led by the Vice-President and members of the disease control division of Health and Human Services.
     It wasn't long before the true scope of the epidemic began to sweep across America with New York City taking the lead in cases testing positive. That was only the medical aspect of the crisis. Depletion of the Strategic National Stockpile (SNS) didn't take long as there was little there to curb the daily rise in victims, especially the mortality rate. In spite of daily White House briefings, which many times ended in hostile accusations by the media and insulting responses from the podium, little was being done to give an effective answer to when the pandemic would pass. Certainly social restrictions were stabilizing the graphs and Congressional stimulus funding was working, but still the so-called apex hadn't been reached.
     In fact, the initial reports called for millions, then reduced to hundreds of thousands, and now down to tens of thousands. The graph was, incredibly, shrinking. In southern Europe the mortality numbers were dropping off even as some nations to the north didn't bother to order social restrictions at all. China reopened the Wuhan doors and so many tourists flooded the Great Wall, it was immediately closed again for fear of not reigniting the disease but just a basic mob stampede.

A.W.O.L: Where in the shelter-in-place world is the Task Force?

White House to skip coronavirus briefing for second day in a row

The White House is not expected to hold a press briefing on Easter Sunday, the second day in a row without one amid the coronavirus pandemic. The White House announced Sunday that President Trump would not appear before reporters on the holiday after he has hosted press briefings almost every day.


     The prediction business is full of components related to hard data to trends to percentages to exponents. To what degree each plays a role may be confusing but one doesn't have to be an economic adviser to understand the basics. If a given number are tested positive and a given number of those die, then that ratio is a good starting point. If that rate declines it means simply the curve is "flattening." An effort to complicate that trend can only lead to inaccurate predictions. If the CDC bases its model on what happened in Italy and Spain and the data doesn't hold up, there's a reason for it hidden somewhere in the population demographics and racial distribution.




That accounts for the sudden announcement that more African-Americans in the United States were falling victim.  The percentage of African-Americans in southern Europe might differ radically than locally. Even though the data from Europe didn't align with the U.S., still it became skewed according to an ethnic variable. Another spike is attributed to nursing home deaths.
     In addition, a coefficient in place to account for social distancing might have been considered a constant when in fact, it may change i.e., (dc/dt), so that the equation reads;

        F(M/P)= (dc/dt)[(dx1/dt)(dx2/dt)….(dxn/dt)]... (+/-)exp(whatever)...

     Where (dxn/dt) in its simplest form represents all the factors taken into account that would change the  ratio (M/P) where M=mortality and P=tested Positive. If "c," mitigation, was taken as constant (c=1) it would need to be dampened   (0.00<c<1.00) to adjust for the falloff of the social measures taken, distancing and sheltering-in-place. In fact, exponents may not be the best way to look at the data even though they are useful for large data sets.

     As irony goes, the author of the novel that was made into the film, The Incredible Shrinking Man,  Richard Matheson, also wrote the story behind The Last Man on Earth (1964), which has been redone several times and in its most compelling version, the Omega Man (1971) starring Charlton Heston.
