There is no large pressure on the US hospital system. Data is limited though as HHS only started to publish aggregate US hospital capacity last month.
While no doubt there is a Covid surge in the US, it is not as large nor as stressing as the initial surge March to May.
Hospitalization is a main focus and deriving currently hospitalized from excess deaths disaggregated from weeky to daily (last published date 2021-01-01), reported by COVID Tracking Project, the CDC hopsital admissions survey COVID-NET, and derived from headline reported deaths, (using a infection Fatality Rate of 0.5%, Infection Hospitalization Rate of 3.9% and hopsitalized Length of Stay (LoS)of 5 days) indicates that hospitalization is dropping and the US Covid infection has peaked.
Headline hospitalizations from the COVID Tracking Projest are grossly overtstated if not fallacious which raises concern for the veractiy of the reported headline deaths data.
SIR models using CDC/NCHS excess deaths and headline daily deaths (JHu) to derive active “Infections” and thereby “Susceptible” and “Resolved”.
The R(0) is given from both death series.
The general perception of how Covid 19 has progressed is not reality as the epidemic was fierce in March to April then having two phases, first in August as Florida and Arizona peaked, then in November to January as Upper Midwest, Eastern Rockies, and finally California peaked and are concluding.
A 30% susceptible is used to build the SIR models.
United States is mapped against Swe_den. Swe_den is the ‘base case’ where there is only mitigation and no suppression such as quarantine or lock-downs. Given the relentless infectiousness of Covid 19 and while treatment is improving there is still no cure; it is thought all countries will replicate Sweden status, especially deaths to percentage infected - that supression only serves to pause this process. Of course this does not consider a vaccine.
The cumulative integral, f(x) of normalized daily deaths to percentage of the population that have been infected seeks to summarize the current status of United States.
It is assumed that United States is the ‘base case’ and without suppression all countries will to various degrees replicate the Swedish case.
Of concern is how low the cumulative f(x) using excess deaths is currently.
